Application

Suitable for below-ground structural foundation surfaces. Typical cast-in-place concrete applications include:

  • Backfilled concrete walls.
  • Earth-covered roofs.
  • Structural slabs.
  • Tunnels.
  • Property line construction.

Property line construction applications include soldier pile and lagging, steel sheet piling, secant/ contiguous piling, shotcrete and stabilized earth retention walls. Applications may include structures under continuous or intermittent hydrostatic pressure.

Suitable for cast-in-place concrete applications and do not cover shotcrete or precast concrete applications. Refer to VOLTEX DS® Product Manuals for additional property line shoring wall construction technique applications.

Description

A waterproofing composite of high strength geotextiles and 4.8 kg/m² of sodium bentonite and an integrally bonded polyethylene liner.

The high swelling, low permeable sodium bentonite is encapsulated between the two geotextiles. A proprietary needle-punch process interlocks the geotextiles together forming a strong composite that maintains the equal coverage of bentonite, as well as protects it from inclement weather and construction related damage.

Once backfilled, VOLTEX DS® hydrates and forms a monolithic waterproofing membrane. VOLTEX DS® contains zero VOC and can be installed in almost any weather condition to green concrete.

 

Features and benefits:

  • Works by forming a low permeability membrane upon contact with water.
  • When wetted, unconfined bentonite can swell up to 15 times its dry volume.
  • When confined under pressure the swell is controlled, forming a dense, impervious waterproofing membrane.
  • The swelling action of VOLTEX DS® can self-seal small concrete cracks caused by ground settlement, concrete shrinkage or seismic action.
  • VOLTEX DS® forms a strong mechanical bond to concrete when the geotextile fibres are encapsulated into the surface of cast-in-place concrete.
  • VOLTEX DS® should not be installed in standing water or over ice.
  • If ground water contains strong acids, alkalies, or is of a conductivity of 2500 μmhos/cm or greater, water samples should be submitted to the manufacturer for compatibility testing.
  • ULTRASEAL XP may be required if contaminated ground water or saltwater conditions exist.
  • VOLTEX DS® is designed for use under reinforced concrete slabs 100 mm thick or greater on a compacted earth/ gravel substrate.
  • VOLTEX DS® requires a minimum 150 mm thick reinforced concrete slab if installed over a concrete blinding.
  • VOLTEX DS® is not designed for split-slab plaza deck construction.
  • VOLTEX DS® is not intended to seal expansion joints; contact CETCO for expansion joint applications.
  • Do not use VOLTEX DS® on masonry block foundation walls.
  • Consult CETCO for special installation guidelines that apply to shotcrete and precast concrete construction.
