THIS MANUAL CONTAINS THE INSTALLATION GUIDE-LINES FOR THE VOLTEX AND VOLTEX DS WATER-PROOFING SYSTEM FOR CAST-IN-PLACE CONCRETE APPLICATIONS, INCLUDING UNDERSLAB, PROPERTY LINE WALLS, AND BACKFILLED WALLS. THIS MANUAL DOES NOT COVER SHOTCRETE, MASONRY BLOCK, OR PRECAST CONCRETE APPLICATIONS. FOR APPLI-CATIONS NOT COVERED IN THIS MANUAL, CONTACT CETCO FOR SPECIFIC INSTALLATION GUIDELINES. BEFORE INSTALLATION, READ THIS MANUAL TO GAIN FAMILIARITY WITH SPECIFIC PROCEDURES AND AP-PLICATIONS. IN THIS MANUAL THE PRODUCT NAME “VOLTEX” IS USED GENERICALLY FOR ALL VOLTEX 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 allofourwaterproofingproducts.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-pandsunderconfinement,forminganimperviousmembranethatwillbe maintained for the life of the structure.
PRODUCT DESCRIPTIONVOLTEX isahighly effectivewaterproofing composite comprisedof twopolypropylene geotextiles and sodium bentonite. The two geotextiles are in-terlocked by a patented needlepunching process which encapsulates and confinesthebentonite.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.

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.

COST EFFECTIVE AND TIME EFFICIENTVOLTEX is designed to be installed on a properly prepared subgrade, withouttheneedtopouraworkingslab.Theproduct’sinherentflexibil-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.

LIMITATIONSVOLTEX 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 waterproofing applicationswheretheproductisproperlyconfined.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”) thickor greater ona compactedearth/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 forwaterproofingpropertylineconstruction.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 specific sub-strate preparation and detailing installation guidelines.

Protectbentonitewaterproofingproductsfromhydratingbeforemate-rialiscontainedwithconcreteorbackfill.Afteranyprecipitation,stand-ingwatershouldbepumpedoffwaterproofingassoonaspossible.
Shoring Wall: Excavation work should provide shoring wall in good condition to receive waterproofing system.

Cut rock excavations and concrete auger cast caisson retaining walls must be sufficiently planar. Typically a shotcrete or grout layer is re-quired to provide acceptable surface to install VOLTEX.

2.2 SOLDIER PILE & LAGGING 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.

In areas with large gaps (up to 63 mm [2–1/2”]) between lagging,AQUADRAIN sheet drainage composite can be installed over the lagging toprovideauniformsurface tomountVOLTEX (Figure2.8).Securelyfasten AQUADRAIN to the lagging surface with washerhead nails be-foreinstallingVOLTEX.Gapslargerthan63mm(2–1/2”)betweenlag-gingshouldbecompletelyfilledwithgrout,wood,extrudedpolystyrene(40psimin.)orcompactedsoilevenifAQUADRAIN is installed prior to VOLTEX.Donotuseplywoodorothersurfacetreatmentoverlargelag-ginggapsthatleavesthecavityvoid.Details2.10through2.12onpage15 illustrate the installation of VOLTEX over the different wood lagging positions relative to the soldier piling.

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 theknuckletostopwaterflow(Figure2.14).ConsultCETCOforBentogrout applications and installation guidelines.
