Tunnel construction is one of the most interesting and also one of the most difficult engineering tasks in civil engineering. Concrete in tunnel construction must fulfil stringent demands in terms of strength, durability and impermeability to water. Invariably joints are necessary and must, despite high loads, be able to ensure the structure is permanently watertight. Injectionworks are indispensable in order to construct a defect free object. This is due to the fact that the building process takes placein a hard to predict interaction of design, mountain and water.

MC-Injekt 2700 stops pressurized water reliably during the construction of the start shaft and simultaneously stabilizes the soil.Sealing the contact area of a TBM (Tunnel Boring Machine) between shaft and subsoil can be ensured by building a sealing ring with MC-Injekt GL-95. This also saves time and money if the downtime of the TBM is minimized. MC-Injekt 2300 top is used for concrete, when the ingress of water and pollutants must be prevented permanently. The special hydro-structural resin MC-Injekt GL-95 TX is a proven technology in retro sealing of voids, cracks and joints in structures, concrete segments or in-situelements. The flexibility and swelling properties meet the highest demands in terms of penetration and permanent sealing requirements.

Tunnels

Whether made from pre-stressed concrete, reinforced concrete, compressed concrete, natural stone or masonry, bridges are animportant part of infrastructure. Increasing traffic volumes, higher axle load limits and aggressive environmental stresses putheavy operational demands on the structure. The protection and reinforcement of bridges are therefore important tasks for whichinjection systems provide innovative solutions.

Force transmitting injection works on load bearing components made from pre-stressed and reinforced concrete under both tension and compression, can be executed safely using MC-Injekt 1264 TF. The low-viscose duromer resin reaches the injectiontarget even when under the influence of dynamic loading. Static cracks and larger cavities are injected with Centricrete UF.This suspension has the typical properties associated with cement based products and is particularly suitable for reinforced concrete and brickwork. For an elastic sealing of cracks, joints or cavities to restore functionality and durability MC-Injekt 2300 topis used. The re-establishment of water tightness can be solved optimally using this elastomer resin. Dampness and water seepage over wide areas of old bridges made of masonry or newer structures made of concrete can be sealed effectively withMC-Injekt GL-95. Waterproofing of the structure can also be performed by injecting of the surrounding subsoil.

Bridges

Roads

Roads, runways and other traffic surfaces experience high dynamic loads and chemical stress such as petrol, oil, or de-icing chemicals etc. Concrete surfaces can only withstand such high stresses if the permissible crack widths and joint distances areadhered to. Individual concrete plates have to be in an even and stable state in order to transfer the rolling loads into the subsoil.

Force transmitting and sealing injection works on load-bearing components made from pre-stressed and reinforced concrete under both tension and compression, can be executed safely using MC-Injekt 1264 TF. Dowel bars, shear connectorsand similar ancillary elements can be permanently bonded to the concrete. A particular advantage of this duromer resin is its performance even under dynamic cycling. For an elastic sealing of cracks or cavities to protect against ingress of pollutants MC-Injekt 2300 top is used. For the injection of voids and static cracks in concrete the mineral suspension Centricrete UF is idealas it strengthens the concrete. Slabs on an unstable foundation can quickly be stabilized with MC-Injekt 2700 in that the substratecan be transformed into a firm, load bearing structure. It can also be used for levelling of the not equally settled concrete slabs.

Hydraulic Engineering

Hydraulic structures are important for shipping, energy production and the regulation of ecological water balance. They are ofgreat significance to the population, industry and the environment. The materials used in these structures, concrete or masonrymust meet special requirements in terms of stability and water impermeability. Protection, reinforcement and sealing of suchstructures are thus important tasks for which injection systems offer innovative solutions.

MC-Injekt 2700 stops strong water ingress during the manufacture and use of hydraulic structures reliably. At the same time MC-Injekt 2700 ensures the stabilization of the subsoil. If cracks and voids are present in the construction material MC-Injekt 2300 top is used to prevent penetration. To prevent water ingress under pressure MC-Injekt 2300 top is used in conjunc-tion with the foaming elastomer MC-Injekt 2033. For sealing of expansion joints the hydro-structural resin MC-Injekt GL-95 TX hasproven on projects around the world to be effective. A rapid and controllable reaction time plus excellent injection properties formthe basis of this effectiveness. All above named products are non toxic, non hazardous and are certified as being suitable for usein contact with potable and ground water.

Drinking Water Structures

Drinking water, our most valuable resource, must be protected from contamination during treatment, transportation and storage. In addition to the lining of facilities, pipelines and tanks, the basic structure of these buildings, must also meet thefunctional requirements to be safe, stable and waterproof.

Classical tasks of concrete injection in terms of sealing are achieved safely with the powerful elastomer resin MC-Injekt 2300 top.The injection parameters of this resin are excellent. The highly elastic reactive resin has been certified for use in contact withdrinking water. MC-Injekt GL-95 is an equally suitable injection system for drinking water, groundwater and soil. It therefore provides the solution for hygienically and technically safe two dimensional external waterproofing. In exceptional cases wherethe foundation has become unstable due to flowing water or ground settlement, MC-Injekt 2700 offers a quick and permanentsolution. This sealing, and at the same time reinforcing resin, also meets the high demands that are required from repair systemsused in areas which come in contact with drinking water, groundwater or the soil.

n Waterproofing of the structure against infiltration and exfiltration

n Closing of cracks to prevent the growth of bacteria and plant life and to ease the cleaning of drinkingwater plants

Wastewater Treatment Plants

Long service life, under conditions of high mechanical and chemical loads, is a requirement for structures in the waste water sector. This requirement can only be fulfilled with regular maintenance and repair activities. Doing so, the high physical and chemical loading of the construction parts and repair products have to be taken into account.

Classical tasks of concrete injection in terms of sealing are achieved safely with the powerful elastomer resin MC-Injekt 2300 top.The injection parameters of this resin are convincing. The highly elastic reaction resin has the chemical resistance needed in typical waste water environments. For injection of brickwork structures MC-Injekt GL-95 offers an interesting alternative. Eventhe finest capillaries can be sealed with this particularly low viscose hydro-structural resin. In the exceptional case that thefoundation has become unstable, MC-Injekt 2700 offers a quick and durable solution. This duromer resin seals and strengthensat the same time. All these injection systems fulfil the requirements for injection products that cure in contact with groundwaterand subsoil.

Residential & Commercial Properties

Property is a long term investment. Properties also represent a status symbol for their occupants. A visitor’s first impression islikely to influence how they feel about their business partner or host. This impression is often formed when the visitor is in theparking area. Damp walls, cracked ceilings and unstable floors generate negative impressions. The causes for such unsightlyappearances can often be eliminated by using injection systems.

Force transmitting injection works on load bearing components made from pre-stressed and reinforced concrete under both, tension and compression, can be executed safely using MC-Injekt 1264 TF. As a result, the stability and durability of structures isrestored. If water is negatively affecting the durability and functionality of structures, MC-Injekt 2300 top is used to prevent pollutants from infiltrating the reinforced concrete. MC-Injekt GL-95 TX can be used for subsequent sealing of leaking joints whereas MC Injekt GL-95 is used to eliminate moisture penetration of surfaces. A foundation with insufficient bearing capacitycan be stabilized using MC-Injekt 2700. In case of fine grained subsoil which is injectable only with materials of low, water likeviscosity, MC-Injekt TS-07 can extend the field of application of MC-Injekt 2700. MC-Injekt TS-07 can also be used in order toincrease the load bearing capacity of masonry structures.

Industrial Structures

Our Solutions:

Industrial buildings are planned and built for intensive use. Such buildings must meet various requirements as a protective and supporting construction. Floor areas are subjected to the highest stresses. Cracks and voids are here, as in the whole construction, not acceptable. If they occur, a remedy must be found quickly, safely and without interfering with the ongoing production. Injection technologies are an efficient remedy for this task.

Force transmitting and sealing injection works on load bearing components made from pre-stressed and reinforced concrete under both tension and compression, can be executed using MC-Injekt 1264 TF. The low viscose duromer cures evenunder the influence of dynamic loading. Furthermore, steel components can also be fixed to the concrete using this resin. Centricrete UF is suitable for the injection of cracks and voids in concrete which are under compression. Mineral suspensionstrengthens the structural concrete. Loose slabs on unstable soil can be stabilized again by forming the subsoil into a solid, highload bearing construction ground. This particular performance is provided by MC-Inject 2700. When other injection products have reached their limits, fine grained soil of a poor injectability can be strengthened using MC-Inject TS-07.

Objectives:n Force transmitting filling of cracks and cavities in

load bearing construction parts such as columns, beams and slabs

n Sealing of cracks, joints and cavities in externalcomponents against water penetration

n Bonding of dowel bars in transverse joints

n Stabilize load bearing subsoil and levelling of floor panels

Building Pits andFoundations

Our Solutions:

Tight building pits create working space for the construction of structures in water and soil. Sudden water ingress into theseareas requires immediate action to prevent delays to the progress of the project and avoid expensive dewatering. Other consequences such as settlement of the surrounding ground or adjacent structures can also be avoided or at least minimised.Ground movement or changing groundwater levels frequently lead to cracks and water damage in existing buildings. In thesecases an injection technique tailored to the individual project provides the right solution.

Bored pile walls, diaphragm walls, slotted walls and secant piles are the main areas of application for injection technologies inrespect of strengthening and sealing. Particular solutions using special injection resins has to be tailored individually accordingto the specific conditions at different sites. The product system MC-Injekt 2700 is an adjustable system which can fulfil a varietyof different requirements. Through the use of additives MC-KAT 27, MC-Additiv ST and MC-Additiv FS, the resin can be optimizedto the given task. The diversity of possible modifications enables you to simultaneously seal and strengthen subsoil, building pitsand structures using just one system. Fine grained subsoil which is not injectable using other injection materials can still bestrengthened using MC-Injekt TS-07.

MC-Injekt 2300 top consists of two components. To mix theresin for application using a one component pump the hard-ener (Part B) is added to the base (Part A) and they are mixedto a streak free homogeneous condition.Suitable mixing devices are a paddle and slow speed (max200 rpm) mixing tools. The mixed resin is poured into thereservoir of the MC-I 510 injection pump and again mixedbriefly.When applied using the MC-I 700 preliminary mixing is un-necessary. The individual components are directly sucked inby the two component pump and are automatically mixed inthe mixing head. Consider mixer type and length in the datasheet for the MC-I 700!MC-Injekt 2300 top is injected with the injection pump MC-I 510 or MC-I 700. Depending on the type of pump, a com-pressor of sufficient capacity should be provided.For suitable packer selection, humidity and thickness of thecomponent are crucial. Most common elastomer resins areinjected by bore packers as these can also be used in waterbearing cracks or voids. MC-Injektionspacker are packerswhich are braced in bore channels with 14 mm diameter. Thebore channels are generally alternately drilled at an angle tothe crack, so that the crack is crossed (see page 38/39).Cavity injections require the component specific placementof the packers in the grid scheme.

Surface sealing is generally not required for injections usingbore packers. The exceptions are when applying to very thinelements or very wide cracks. In such cases MC-FastpackPU solid is a convenient sealing material. The preconditionsare largely dry component surfaces. On wet surfaces therapid setting mortar MC-Fix ST can be used. Against highinjection pressure MC-Fix ST has limited loadability.Unforeseen leaks may occur on almost any site. Rapidsetting mortars such as MC-Fix ST may be used to seal thesequickly.Tools and machines can be cleaned with special cleaningagents. For polyurethane based elastomer resins MC-Verdün-nung PU is available.Once the injection material has hardened, all packers areremoved; injection holes are sealed with mortars and sealingmaterial is removed with a hammer and chisel.When working with reactive resins and high pressure pumps,the appropriate safety precautions must be taken. Theinstructions in the safety data sheets and/or the instructionmanuals must be followed.

Taking the product specific properties into account, as analternative MC-Injekt 2300 flow or MC-Injekt 2300 can beused.

When application is onto a dry and solid substrate, MC-Klebepacker may be used for injection. Adhesionpackers are fixed directly onto the crack. The spacing between the packers should be approximately equal to the thickness of the element to be injected. The remainingcrack length between the packers is sealed (see page 38/39).

Alternatively to the high pressure injection MC-Fastpack 2300top may be injected over MC-Hammerpacker LP 12 orMC-Surfacepacker LP (on dry parts) by the MC-FastpackPower Tool in cracks > 0.2 mm.

Sealing Injection against Pressurised Water

MC-Injekt 2300 top /MC-Injekt 2033

The high foaming factor of MC-Injekt 2033 makes its use veryeconomical. Pressurised water is stopped quickly.

The very low viscosity of MC-Injekt 2300 top enables a securepermanent injection of the pre-injected areas by the elasto-mer foam. Nevertheless, the inevitable pre-injection of theelastomer foam has to be limited only to the application areaof pressurised and strong flowing water.

For cavity injection in construction parts the use of MC-Injekt 2033 should be avoided. Otherwise the importantpermeability of cavities for the successful permanent sealingwill be limited.

MC-Injekt 1264 TF consists of two components. The hardener(Part B) is emptied into the base component (Part A) andmixed until a streak free consistency is achieved.

Suitable mixing devices are a paddle and slow speed (max 200 rpm) mixing tools. The mixed resin is poured into thereservoir of the MC-I 510 injection pump and again mixedbriefly.

MC-Injekt 1264 TF can be injected with the injection pumpMC-I 510. A compressor of sufficient capacity should be provided.

For the suitable packer selection, humidity and thickness ofthe component are crucial. Frequently duromer resins are injected via adhesion packers because usually dry crackedges are required for the injection resin. Under these con-ditions, the use of adhesion packers is economical. For injection with MC-Klebepacker it is necessary to prepare theconcrete surface along the crack. The substrate must be dryand stable. Adhesion packers are applied directly onto thecrack. The remaining crack length between the packers issealed (see page 38/39).

MC-Fastpack PU solid is particularly suitable as adhesive andsurface sealing. MC-Fastpack PU solid is applied from readyto use cartridges.

Unforeseen leaks may occur on almost any site during injec-tion. The rapid setting mortar MC-Fix ST may be used to sealthese quickly.

Tools and machines can be cleaned with special cleaningagents. For epoxy based duromer resins MC-Verdünnung EPis available.

Once the injection material has hardened, all packers areremoved and any unnecessary or unsightly sealing materialsare removed with a hammer and chisel.

When working with reactive resins and high pressure pumps,the appropriate safety precautions must be taken. Theinstructions in the safety data sheets and/or the instructionmanuals must be followed.

Taking the product specific properties into account, MC-Injekt 1264 compact can be used as an alternative. MC-Injekt 1264 compact offers the special advantage of moisture compatibility.Alternatively to the high pressure injection MC-Fastpack 1264compact may be injected by the MC-Fastpack Power Tool incracks > 0.3 mm.

Centricrete UF


Centricrete UF consists of the powder component CentricreteUF and the liquid, Centricrete Additiv.

To mix the suspension the liquid component is poured into themixer with water and the powder component is slowly addedwhile mixing. After mixing for about 10 minutes at the appro-priate mixing speed the cement suspension becomes homo-geneous and is ready for use.

Suitable mixers are, colloidal mixers with high shear energy.The mixed suspension is transferred to the hopper of the MC-I 910 injection pump and is mixed continuously.

Centricrete UF is injected with the injection pump MC-I 910. A compressor of sufficient capacity should be provided.

The selection of a suitable packer depends on the moisturecontent and the thickness of the element or structure to beinjected. Packers with strong pressure reducing check valves(> 5 bar) are not suitable. Most suitable are packers with largevents, such as the MC-Schlagpacker or MC-Surfacepacker LP.

Mineral suspensions are frequently injected into cavities.Here MC-Schlagpacker are preferred. MC-Schlagpacker arebore packers with seven seals and are hammered into 18 mmdiameter holes. The holes are usually drilled at a defined angleto the crack, so that the crack is crossed in the centre of thestructure. Cavity injections require spacing of the packers in agrid pattern (see page 38/39).

Surface sealing is recommended when injecting cement suspensions. MC-Fix ST is suitable for use as sealing mate-rial. Against high injection pressure MC-Fix ST is only limited loadable.

Unforeseen leaks during injection may occur on almost anysite. The rapid hardening material such as MC-Fix ST may beused to seal these quickly.

Tools and machines may be cleaned with water.

Once the injection material has harden, all packers are removed and if necessary, injection holes are sealed withmortar. Any excess, unnecessary or unsightly sealing mate-rial is removed using a hammer and chisel.

When working with alkaline substances the appropriatesafety precautions should be taken. Please refer to the rele-vant material safety data sheets.

When application is onto a dry and solid substrate, MC-Surfacepacker LP may be used for injection. Adhesionpackers are fixed directly onto the crack. They must belocked with a ball valve with a large pass through opening.The spacing between the packers should be approximatelyequal to the thickness of the element to be injected. Theremaining crack length between the packers is sealed (seepage 38/39).

Wider cracks or large cavities may be injected with Centri-crete CS.

Taking the product specific properties in account, as an alter-native Centricrete MS can be used for injection in masonry.

The holes are usual-ly drilled at a defined angle to the crack, so that the crack iscrossed in the centre of the structure (see page 38/39).

Cavity injections require spacing of the packers in a grid pattern.

Surface sealing is recommended when injecting cement suspensions. MC-Fix ST is suitable for use as sealing mate-rial. Against high injection pressure MC-Fix ST is only limitedloadable.



Once the injection material has harden, all packers are removed and if necessary, injection holes are sealed withmortar. Any excess, unnecessary or unsightly sealing mate-rial is removed using a hammer and chisel.

When working with alkaline substances the appropriatesafety precautions should be taken. Please refer to the rele-vant material safety data sheets.

When application is onto a dry and solid substrate, MC-Surfacepacker LP may be used for injection. Adhesionpackers are fixed directly onto the crack. They must belocked with a ball valve with a large pass through opening.The spacing between the packers should be approximatelyequal to the thickness of the element to be injected. The remaining crack length between the packers is sealed(see page 38/39).

Cracks, rigid joints and cavities in concrete and masonrymay be injected with Centricrete CS.

Taking the product specific properties into account, as analternative Centricrete MS can be used for injection in masonry.

n Cracks, rigid joints and cavities in masonryArea of Application


System Variations

Due to its water like viscosity MC-Injekt TS-07 penetrates eventhe finest pores. Substituting the air and the water in the mediait creates a dense and water tight structure.

After curing MC-Injekt TS-07 is viscoplastic rigid. Injected in aporous media it forms a hard and durable filling material, whichincreases the strength of the structure. Injected into loose soilsit forms a solid and strong compound with the soil particles.

The application time of MC-Injekt TS-07 can be controlled bythe adjustment of the concentration of the sub component A2.In this way the pot life of the material can be tailored to the specific site requirements which depend on temperature, permeability of the substrate and other parameters.

MC-Injekt TS-07


MC-Injekt TS-07 is a multi-component acrylic based resin. Thetwo injection components A and B are prepared from severalsub components on site.

The mixing of the injection components A and B must be carried out in separate containers and separated by open ground, so that neither subsets nor splashes can get in theother component.

Component A is mixed from sub components A1 and A2. Theconcentration of A2 in this mixture determines the product’sreaction time. Component B is mixed from sub components B1and B2, where the powder component B2 is dissolved in a defined volume of water and then added to sub component B1.

Suitable mixing tools are mixing paddles made of wood, plasticor non ferrous metals. The reactivity can be assessed bymixing a small sample of material and measuring the time frominitial contact to gel formation. Due to the material’s high reac-tivity the sample size however must not exceed 100 ml.

The mixing of the reactive resin components is performed inthe mixing head of the injection pump.

MC-Injekt TS-07 is injected with the two component injectionpump, MC-I 700. A compressor of sufficient capacity should beprovided.

The injection is carried out through packers in structures orlances in the structure or construction ground. In the case ofinjection into the structure, we recommend MC-Schlagpacker.Depending on the site specific conditions MC-HammerpackerLP 12 may be also used.

MC-Schlagpacker are hammered into 16 mm diameter holes.MC-Hammerpacker LP 12 are hammered into 12 mm diameterholes. The bore holes are drilled in a grid of about 200-400 mmspacing (see page 38/39).

Surface sealing is usually not required as the fast reactingresin quickly seals off any leakage.

Within the material’s application time tools and machines maybe cleaned with water. Partially or fully reacted material canonly be removed mechanically.

After curing of the material, the packers can be removed andthe injection holes closed, e.g. with the rapid setting mortarMC-Fix ST.

When working with reactive resins the appropriate safetyprecautions should be taken. Please refer to the relevant material safety data sheet.

For injections into flowing water usually the higher viscoseand fast reacting MC-Injekt 2700 is the ideal solution. With MC-Injekt 2700 significantly higher strengths can beachieved.

Without strength requirements the hydro-structural resinsMC-Injekt GL-95 and MC-Injekt GL-95 TX meet the sealingtasks.

Area of Application


System Variations

MC-Injekt GL-95 is particularly low viscose. It can close andseal the finest flow path of water.

The soft elastic hydro-structural resin can withstand veryhigh levels of deformation without damage. After curing,small damages can be sealed by the limited post swelling ofthe hydro structural resin itself.

For the permanently constant function of MC-Injekt GL-95,constant contact to water or dampness is necessary. This is sufficient in order of the water content of subsoil or the compensation moisture content of masonry.

MC-Injekt GL-95


MC-Injekt GL-95 is a multi component hydro-structural resin. The two injection components A and B are prepared fromseveral sub components on site.

The mixing of the injection components A and B must be carried out in separate containers and separated by openground, so that neither subsets nor splashes can get in theother component. Component A is mixed from sub compo-nents A1, A2 and A3, wherein the sub components A2 and A3 are poured one after another in the container of the sub component A1.

Sub component B is dissolved in water. The concentration ofthe solution determines the reaction time which is dependenton ambient temperatures. Using a curing trial the reactivity ischecked

Suitable mixing tools are mixing paddles made of wood, plastic or non ferrous metals. The mixing of the reactive resincomponents is performed in the mixing head of the injectionpump.

MC-Injekt GL-95 is injected with the two component injectionpump MC-I 700. Pay attention to the specified type and number of mixing elements (see technical data sheet of MC-I 700). A compressor of sufficient capacity should be pro-vided.

The level of the individual components must be constantlymonitored, to ensure evenly constant material usage.

Injection is generally carried out through bore packers. For masonry injections we recommend MC-Stahlpacker18/300. These packers are placed into 18 mm diameter holes.The drill holes and bore packers are distributed in a regulargrid pattern over the surface to be sealed. For injection intostructures a packer spacing of 200-400 mm is recommended.In order to carry out a curtain injection in structure near ground, special packers with equivalent length to the com-ponent thickness are required. Depending on the perme-ability of the subsoil the packers are usually placed at 400-800 mm spacing (see page 38/39).

Surface sealing is usually not required as the resin quicklyseals off any leakage. If necessary, the injection process maybe delayed or interrupted to allow time for the resin to sealthe leaks.


Once the injection material has cured, all packers are removed and all drill holes are sealed component deep withmortar.

When working with reactive resins and high pressure pumpsthe appropriate safety precautions should be taken. Pleaserefer to the relevant material safety data sheets.

Taking the product specific properties into account, as analternative MC-Injekt GL-95 TX can be used. The polymer-enhanced version of the MC-Injekt GL-95 has significantlybetter characteristics for the sealing of joints and areas witha high pressure gradient.

Significantly longer reaction times are offered by the products MC-Injekt GL-95 TR and MC-Injekt GL-95 TX-TR. Inaddition, all MC-Injekt GL resins can be set to longer reactiontimes using the MC-Inject Retarder GL.

Area of Application


System Variations

Due to the very low viscosity MC-Injekt GL-95 TX can beinjected both into large voids and fine porous media.The polymer reinforced MC-Injekt GL-95 TX features an extremely high degree of reversible deformability. It also hasexcellent adhesion to concrete and a wide range of otherconstruction materials. This makes it the ideal product forsealing joints and areas with high water pressure.The polymer reinforcement makes MC-Injekt GL-95 TX lessprone to dilution in water than traditional hydro-structuralresins. Therefore this material is also the right choice forinjection into large waterlogged voids.

For the permanently constant function of MC-Injekt GL-95 TX,constant contact to water or dampness is necessary. This issufficient in order of the water content of subsoil or the com-pensation moisture content of masonry. Permanent contactwith air should be avoidedThe reaction time of MC-Inject GL-95 TX can be controlledmanually by the starter concentration. Thus, the applicationtime of the material can be adjusted to the on site specificconditions, such as temperature.

MC-Injekt GL-95 TX is a two component polymer enhancedhydro-structural resin. The two components are prepared onsite from several sub components.The mixing of the injection components A and B must be carried out in separate containers and separated by open ground, so that neither subsets nor splashes can get in theother component.Component A is mixed from sub-components A1, A2 and A3,wherein the sub components A2 and A3 are poured one afteranother in the container of the sub component A1 and aremixed thoroughly using a non metallic stirrer.Component B is prepared by dissolving sub component B insub component B1. The concentration of the solution deter-mines the reaction time, which is also dependent on temperature.The reaction time can be assessed by mixing a small sampleof material (e.g. 200 ml) and measuring the time from initialcontact to gel formation.Suitable mixing tools are wood, plastic or non ferrous metals.Due to the resin’s short reaction time, the mixing of the reac-tive resin components is performed in the mixing head of thetwo component injection pump.MC-Injekt GL-95 TX is injected with the two component injection pump MC-I 700.

Partially or fully reacted material canonly be removed mechanically.Once the injection material has cured, all packers are removed and all drill holes are closed, e.g. with the rapidsetting mortar MC-Fix ST. The curred material is to protectagainst dry-out. In joints, an air-side drying of the hydro-struc-tural resin can be prevented by a joint filling material.When working with reactive resins the appropriate safetyprecautions should be taken. Please refer to the relevantmaterial safety data sheet.

High ambient temperatures can considerably accelerate thehardening of the material. Significantly longer reaction timesare offered by MC-Inject GL-95 TX-TR.All MC-Injekt GL resins can be set to longer reaction timesusing the MC-Inject Retarder GL.For flexible sealing injections of cracks and constructionjoints in reinforced concrete, it is preferable to use the lowviscose elastomer resin MC-Injekt 2300 top.

System Variations

MC-Injekt 2700 consists of two components which aftermixing react in a short time to a visco elastic resin. Withoutwater contact it becomes a solid reaction product. Blendedwith water it will create a solid foam.

Due to its short reaction time the mixing of the reactive resincomponents is performed in the mixing head of the injectionpump.

MC-Injekt 2700 is injected with the two component injectionpump MC-I 700. Take note of mixer and mixing length in the data sheet for the MC-I 700! A compressor of sufficientcapacity should be provided. This pump automatically takesin both resin components. The end of the suction hoses mustbe immersed completely inside the separate individual components and must be fixed so that they cannot easily be dislodged. The level of the individual components must beconstantly monitored, to ensure evenly constant materialusage.

Against pressurised water resins are injected through borepackers. Depending on the situation on site, MC-Stahlpacker18/300 with sufficiently large flow opening should be selected. It is recommended to select an opening diameterthat corresponds roughly to the inside diameter of the injec-tion pump’s hose.

Surface sealing is of no use when injecting with borepackers, if pressurised water is flowing through the crack.

Tools and machines may be cleaned using special cleaningagents. MC-Verdünnung PU is available for polyurethanebased resins. When using solvents, the operating instructionsfor the pump have to be observed. In particular, the resis-tance of the seals to the solvents must be checked.

After curing of the injection material, detachable packers orpacker parts are removed or near surface separated andremaining openings are sealed with mortar.

When working with reactive resins the appropriate safetyprecautions should be taken. Please refer to the relevantmaterial safety data sheets.

Taking the product specific properties into account as analternative MC-Injekt 2700 L can be used. This type of resinreacts slower compared with MC-Injekt 2700. With MC-Injekt2700 L crack and cavity injections with MC-I 510 is possible.For MC-Injekt 2700 special additives are available with whichthe reaction can be accelerated, the formation of foam pre-vented or tailored thixotropy adjusted.

MC-KAT 27 is used to accelerate the reaction and MC-AdditivST for a faster, thixotropic set up. With both additives require-ments for a fast, non-foaming reaction under water can beachieved. The addition of MC-Additive FS in conjunction withwater results in a controlled, stable foam.On site conditions may require high flow rates of the 2-com-ponent injection pump.

Crack Characteristics

Attachment of adhesion packers on the component surface with a spacing equal to the crack depth (with surface sealing)

Attachment of bore packer in boreholes at a spacing of half the crackdepth on alternate sides of the crack (usually without surface sealing).

The location of packers and the direction and depth of boreholes must be such as to allow a complete filling of the crack. To guarantee a successful injection, the recommended dimensions should not be deviated from more than 10-15 %. For crack depths that significantly exceed 30 cm (adhesive packer) respectively 60 cm (bore packers), adhesive packers where applicablefrom opposing crack openings or bore packers in multiple rows have to be placed. Injection direction: from bottom to top.

Arrangement of Adhesion and Bore Packers for Crack Injection

Attachment of bore packers in drilled holes(usually without surface sealing)

Damp areas are covered with a grid pattern of packers. The distance and depth of the drilled holes are according to the extentand nature of the damaged area. For most situations the spacing is equal to A-sof the construction thickness and the depth shouldbe equal to S-e of the construction thickness.

In masonry structures the boreholes should be drilled at an angle to the mortar joint (approx. 30–45°), so as to cross as many jointsas possible.
