About our Waterproofing Products
What Is Sodium Bentonite?
Sodium bentonite is a yellowish-gray, inorganic and nontoxic natural mineral chiefly found in the Black Hills region of the United States. It consists largely of montmorillonite (aluminum silicate), a highly expansive clay having the unusual characteristics of cohesion, binding, sealing, and thickening. Sodium bentonite originated from volcanic ash, combining with saltwater millions of years ago. The crystal lattice structures of sodium bentonite are much thinner and more easily separated by hydration than those of other clays. When wetted and separated, the surface area of bentonite increases many times. This increased surface area, along with irregular dispersion of the clay platelets, resist water penetration, thus forming a very low permeable barrier.
Will Volclay Bentinite Dry Out After Being Hydrated?
No. Volclay Bentinite does not dry out after being hydrated in a below-grade waterproofing application. Volclay Bentinite, once wetted, will remain hydrated even when the moisture content in the adjacent soils decrease. This is because Volclay has been forced-dried at 650°F (330°C) to an 8% bonded moisture content from its natural 25-30%. Therefore, Volclay Bentinite has a great affinity for water, and once mechanically bonded, doesn't let it go.
Will Volclay Work In The High Saline Soils Of Coastal Regions?
Yes. A special Volclay Bentonite, Volclay Bentonite CR (Contaminate-Resistant), has been designed to work in soils with high concentrations of salts found in coastal regions. Volclay Bentonite CR is also resistant to other industrial chemicals that may be in the soils. A simple test of the groundwater from the construction site will produce results indicating whether standard Volclay or Volclay Bentonite CR is required for that specific project.
Does Volclay Have To Be Immediately Hydrated After Backfilling?
No. Volclay Bentonite does not have to be fully hydrated upon installation. Like most other waterproofing membranes, Volclay Bentonite will remain dormant until water comes in contact with the waterproofing. When water does contact Volclay Bentonite, the Volclay Bentonite immediately hydrates, forming a low permeable barrier.
For Underslab Applications, Does Volclay Bentonite Require A Working Mud Slab?
No. Volclay Bentonite , in most cases, does not require a working mud slab to be installed over. The reason for this is that Volclay Bentonite does not rely on adhesion to function as a waterproofing membrane. Remember, a mud slab traditionally is made of weak concrete mix and usually cracks. Therefore, you are not adhering the waterproofing to the structural slab, but waterproofing the mud slab, which is typically made of a weak concrete mix and is susceptible to cracking.
Will Volclay Bentonite Work With Property Line Construction?
Yes. Volclay Bentonite waterproofing systems are ideal for blind-side property line construction. Simply install Volclay Bentonite to the retaining wall and pour the concrete in a single-sided form. Typical applications include soldier pile and wood lagging, metal sheet piling, earth and shotcrete retention walls, and concrete cassoin construction.
How Soon After The Concrete Pour Can Volclay Bentonite Be Installed?
Volclay Bentonite waterproofing systems can be installed to concrete as soon as the forms are removed. There is no seven to 28-day waiting period. Therefore, the work can be completed sooner and the project can proceed on time.
Can Volclay Bentonite Be Installed In Freezing Temperatures?
Yes. Unlike most peel-n-stick and fluid-applied waterproofing membranes, Volclay Bentonite can be installed when temperatures are below freezing. This allows work to proceed in the winter months on time, as scheduled.
