A bentonite geotextile waterproofing system.
Suitable for below-ground vertical and horizontal structural foundation surfaces. Typical cast-in-place concrete applications include:
Property line construction applications include soldier pile and lagging, secant/ contiguous piling, steel sheet 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® Product Manuals for additional property line shoring wall construction technique applications.
A waterproofing composite of high strength geotextiles and 4.8 kg/m² of sodium bentonite. The high swelling, low permeable sodium bentonite is encapsulated between a non-woven and woven geotextile. 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® hydrates and forms a monolithic waterproofing membrane. VOLTEX® contains zero VOC and can be installed in almost any weather condition to green concrete.
