Bentonite Suction Force Ensures a Long Lasting Waterproofing Solution

Sodium bentonite generates a powerful suction force which can hydrate itself even if no water is added to it by drawing moisture from the soil in the surrounding area. Bentonite is capable of producing a suction force of 650psi — this is enough suction to draw water from even very dry soils.

As the bentonite hydrates, the suction force is reduced to the point where an equilibrium is reached between the suction of the bentonite and the suction of the adjacent soil. The point where Voltex reaches equilibrium is around 100% moisture content. While this may sound high to the layperson, it is worth noting that Voltex is considered fully hydrated at 150-250% depending on the confining pressure. Even if the Voltex loses some of its moisture over time, there is still a suction force present that would allow additional water to be absorbed if it were to become available.

Volclay Waterstop RX

Allco Waterproofing Solutions

View Product

Waterstop-RX is an active bentonite / butyl-rubber based waterstop designed to stop water infiltration through cast-in-place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete.

Applications include both vertical and horizontal non-moving concrete construction joints, new to existing concrete construction, irregular surfaces, and around through-wall penetrations, such as plumbing and utility pipes.

Additionally Waterstop-RX can seal around concrete pilings and steel H-piles passing through the slab. Waterstop-RX works in both continuous hydro-static and intermittent hydro-static conditions.

B2 DURABILITY: Performance B2.3.1 (a) not less than 50 years.
E2 EXTERNAL MOISTURE: Performance E2.3.3.
F2 HAZARDOUS BUILDING MATERIALS: Performance F2.3.1. The Volclay Waterproofing System meets this requirement and will not present a health hazard to people.
