PRODUCT TYPES.
WHAT IS SODIUM BENTONITE?Sodium bentonite is a non-toxic mineral of volcanic origin found exten-
sively in the Black Hills region of North America. Bentonite is specially
processed by CETCO to achieve the highest possible performance for
allofourwaterprooingproducts.CETCOalsomanufacturersacontami-nant resistant bentonite to assure optimum performance in moderate
saline or contaminated water.
Bentonite prevents water intrusion by forming a dense monolithic mem-
brane upon contact with water. The specially processed bentonite ex-
pandsunderconinement,forminganimperviousmembranethatwillbe maintained for the life of the structure.
PRODUCT DESCRIPTIONVOLTEX is a highly effective waterprooing composite comprised of twopolypropylene geotextiles and sodium bentonite. The two geotextiles are in-
terlocked by a patented needlepunching process which encapsulates and
coninesthebentonite.VOLTEXDS® integrates a polymer liner bonded to
the outside surface of the nonwoven geotextile. The polymer liner provides
extremely low permeabilities for water vapor transmission.

VOLTEX forms a continuous mechanical bond to concrete. This bond is created when VOLTEX’s strong geotextileibersareencapsulated by poured concrete as shown in the illustration

Installation of VOLTEX is fast and easy. Simply position the product into
place and fasten. VOLTEX can be installed on green concrete, in virtu-
ally any weather, without the need for primers or adhesives. VOLTEX
can be easily cut on site to form around corners and penetrations. The
result is always a consistent self-sealing membrane.
DURABILITYThe VOLCLAY® sodium bentonite in VOLTEX is uniformly encapsulated
between two high-strength woven and non-woven geotextiles. CETCO’s
state-of-the-art needlepunching process interlocks the geotextiles,
preventing the displacement of bentonite prior to, during, and after in-
stallation. The geotextiles provide superior protection from inclement
weather and construction-related damage, without requiring to use a
protection course.
SUPERIOR ADHESIONWhenconcreteispouredagainstVOLTEX,atenaciousmechanicalbondis created with VOLTEX’s high strength geotextile. Independent labora-
torytestingconductedinaccordancewithASTMD903(mod.)(PeelAd-
hesiontoConcrete),yieldsanaverageadhesionvalueof2.6kN/m(15lbs/in).ThemechanicalbondwillholdVOLTEXinintimatecontactwiththe concrete should any ground settlement occur, thereby preventing

COST EFFECTIVE AND TIME EFFICIENTVOLTEX is designed to be installed on a properly prepared subgrade,
withouttheneedtopouraworkingslab.Theproduct’sinherentlexibil-ity allows for easy installation on irregular surfaces and rough property
line forming. VOLTEX can be installed as soon as the forms are stripped;
there is no waiting for the concrete to cure.

LIMITATIONS
VOLTEX should only be installed after substrate preparation has
been properly completed and is suitable to receive the waterproof-
ing system. Concrete work should use conventional cast-in-place
formsthatproduceasmoothsurface.Donotusestay-in-placecon-
crete forming; use removeable forming products only.
VOLTEX is designed for below-grade waterprooing applicationswheretheproductisproperlyconined.VOLTEXproductsshouldnotbe installed in standing water or over ice. If ground water contains
strongacids,alkalies,orisofaconductivityof2,500μmhos/cmorgreater, water samples should be submitted to the manufacturer
for compatibility testing. Ultraseal may be required if contaminated
ground water or saltwater conditions exist.
VOLTEX isdesigned foruseunder reinforcedconcrete slabs100mm (4”) thick or greater on a compacted earth/gravel substrate.VOLTEXrequiresaminimum150mm(6”)thickreinforcedconcreteslab if installed over a mud slab. VOLTEX is not designed for split-
slab plaza deck construction.
VOLTEX is not designed to waterproof expansion joints. Do not use VOLTEX on masonry block foundation walls. Con-sult CETCO for special installation guidelines that apply to shotcrete and precast concrete construction.
In this manual, the product name “VOLTEX” is used generi-cally in the installation and application guidelines for the applicable products: VOLTEX, VOLTEX CR, VOLTEX DS and VOLTEX DSCR.

The use of construction techniques described in this section allow the
exterior building dimensions to coincide with the property line, thereby
maximizinguseofavailablelandforbuilding.VOLTEX/VOLTEXDShasbeen proven to be one of the most effective and widely used means
forwaterprooingpropertylineconstruction.Cast-in-placepropertylineconstruction methods include soldier pile & lagging, metal sheet piling,
earth formed shotcrete retention walls, and auger cast caisson walls.
For all property line construction methods, VOLTEX is installed to the shoring wall prior to concrete placement.Install VOLTEX or VOLTEX DS with the dark grey (woven) geotextile inward, facing the installer, away from the shoring wall. Refer to each applicable construction method in Section 2 for speciic sub-strate preparation and detailing installation guidelines.

2.3 METAL SHEET PILING RETAINING WALLVerify the following substrate preparation work has been completed.
Then install VOLTEX following the property line installation guidelines in
Section 2.1 on page 12 and 13. Special knurled powder-actuated fas-
teners are recommended to secure VOLTEX to the metal sheet piling.
Preparation:Trowela12mm(1/2”)thicklayerofBENTOSEAL along
all sheet piling knuckles. Fill voids or cavities at tieback plates with ce-
mentitious grout or compacted soils. If excessive water is penetrating
the sheet piling knuckles, Bentogrout can be injected to the outside of
