PASSION THAT HAS PRESERVED FOR OVER

40 YEARSStirling Lloyd is at the forefront of technological developments in the world of construction and civil engineering.

Established over 40 years ago with a single-minded commitment to developing new and more effective ways to extend the life of structures, Stirling Lloyd has become a global leader in the development, manufacture and applications of waterproofing and structural protec-tion membranes and systems.

With a truly global reach Stirling Lloyd has a worldwide network of offices, associates and authorised contractors that allows us to provide a complete solution, ensuring the success of our projects around the world.

THE DRIVE FOR CHANGESince the 1970s Stirling Lloyd has been protecting the worlds principal infrastructure assets using unique seamless waterproofing techniques. These techniques, based on our advanced sprayed resin technology, have been developed to address the complexities of tunnel construction and the challenges that these environments pose for materials.

Stirling Lloyds range of tunnel waterproofing membranes more than meets the demands of these complexities, providing long lasting, 100% effective protection for these important structures.

As industry standards become ever more demanding our research teams continue to shape the future of structural protection - setting the performance benchmarks for tomorrow and ensuring that Stirling Lloyd systems continue to protect the worlds most important structures.

The proofSTIRLING LLOYD TUNNEL WATERPROOFING SOLUTIONS

SEAMLESS TECHNOLOGYEliminating Leaking Seams

Seams and joints in sheet waterproofing systems however well they have been welded are potential weak points creating a risk of failure. Stirling Lloyds liquid spray applied systems provide a continuous membrane, eliminating the risk of waterproofing failure.

TESTINGEnsuring 100% Effective Protection

Confirming the integrity of an applied tunnel waterproofing system can be a challenge. Often leaks are only discovered once it is too late to rectify them.

Testing the waterproofing system before encapsulation or immersion using a non-destructive and reliable method, proving that the waterproofing is 100% effective, is essential. As part of our unique on-site quality programme all our membranes are subject to electronic integrity testing in-situ that confirms complete waterproofing has been achieved.

RAPID INSTALLATIONSubstantially Reducing Build Times

Liquid, seamless application eradicates the need for time consuming complex detailing, which together with the use of high output spray equipment and the materials fast cure, ensures rapid application, facilitating contract progression. In tunnels of NATM/SEM/SCL design, Integritank HF enables the use of sprayed concrete for the secondary lining, which dramatically reduces build times,

while on refurbishment projects -our membranes rapid installation and one hour cure time provides a fast return to service with less disruption to tunnel users.

THE COMPOSITE EFFECTDramatically Reducing Costs

In tunnels of NATM/SEM/SCL design the use of Integritank HF can further reduce costs. Other waterproofing systems do not allow the primary concrete lining to be considered as a structural element. The high bond strength of Integritank HF to the primary and secondary concrete linings facilitates a composite action, resulting in a dramatic reduction in the quantity of concrete required, excavation needed, spoil generated, environmental impact and cost.

It is estimated that the construction costs of the waterproofing and secondary lining may be reduced by up to 30% due to this composite effect.

CRACK BRIDGINGPreventing Future Leaks

All new concrete suffers from some degree of cracking, with bored tunnels being particularly at risk from ground squeeze and drying shrinkage. Inflexible waterproofing that is bonded to the concrete will crack, as the concrete moves and cracks resulting in an ineffective system and a leaking tunnel.

Stirling Lloyds tunnel waterproofing solutions have excellent crack bridging capabilities and so retain their integrity even if the concrete suffers cracking.

TWO COAT MEMBRANESComplete Coverage

Stirling Lloyd always use two coat systems for tunnel waterproofing. The coats are applied in contrasting colours to allow for visual coverage checking prior to formal thickness tests, ensuring that all areas are appropriately covered. The two coat application gives the confidence that in the unlikely event a minor defect occurs in the first coat it will be rectified by the application of the second coat.

ROBUST AND DURABLEWithstanding Site Challenges

Any tunnel waterproofing membrane must be robust; site traffic, steel fixing, concrete placement and high levels of water pressure all present on-site challenges. Stirling Lloyds systems are engineered for long term durability, making them ideal for immersion, burial and covering by a sprayed secondary lining.

TECHNICAL SUPPORTExpert Worldwide Assistance

With over 40 years experience within the construction and civil engineering industries Stirling Lloyds technical expertise is unsurpassed. Throughout the whole construction process, from initial design and planning through to project completion, Stirling Lloyd provides technical support globally; essential when changing site conditions or unforeseen challenges need to be addressed.With assistance available by telephone, online and on site, Stirling Lloyd is your global waterproofing partner.

Immersed Tube and Cut and Cover Tunnels are subjected to a wide range of harsh environments and chemicals, so effectively protecting these important assets is essential.

Internal waterproofingINTEGRITANK HF

BORED TUNNELSNATM, SEM & SCLCONSTRUCTION METHODSVarious systems have been used to attempt to waterproof tunnels constructed using these methods, but few have successfully addressed the particular challenges presented.

The development of the Integritank HF system has taken this uncertainty out of waterproofing bored tunnels. Integritank HF is based on advanced resin technologies developed specifically for use in the confined spaces and conditions of a tunnel construction environment and for application between primary and secondary concrete linings.

It is a robust, spray applied system, which forms a seamless, intimate bond with the concrete so water cannot penetrate through the membrane and circulate behind it. Once the membrane has been applied, prior to encapsulation it is tested using a non-destructive electrical integrity test; proving it is 100% waterproof.

Integritank HF system is a spray applied waterproofing membrane based on advanced resin technology which:

Provides a 100% effective, watertight membrane

Is proven watertight prior to encapsulation

Achieves a strong bond to the primary lining

Has a rapid and reliable 360 coverage

Is robust enough to withstand application of shotcrete

Waterproof to >100 bar pressure

Is safe for use in confined spaces

Makes detailing simple

Eliminates weak and vulnerable seams

Has a service life to match the 100+ year design life of a tunnel

Has excellent in-situ crack bridging capabilities

Suspended Deck waterproofingELIMINATOR

Where suspended decks form the roadway or rail track within a tunnel, the chosen waterproofing system has to do more than protect the concrete slab from corrosion. On a roadway it must also provide a sufficiently strong bond with both the substrate and the surfacing to ensure the heavy braking forces of the traffic do not cause the asphalt to deform and subsequently break up. This requirement is even more critical in tunnels as there is usually a much-restricted thickness of asphalt, making the shear forces exerted even greater. In addition, the system must be tough and resilient enough to withstand the high temperatures and physical pressure exerted by the asphalt application.

Eliminator is a high performance waterproofing system which has been used throughout the world, which:

Provides a 100% effective, watertight membrane

Is proven through electrical integrity testing

Achieves a strong bond to both the concrete and asphalt

Has a rapid application and cure

Is highly resistant to various aggressive chemicals
