VOLCLAY^® PANELS

Bentonite Waterproofing System with LEED™ Environmental Merits

Introduced in 1963, the Volclay Panel^® was the first commercially available bentonite waterproofing system and maintains being one of the most environmentally sensitive waterproofing systems still today. Once installed and backfilled against, the corrugated kraft board biodegrades, and the bentonite hydrates and forms a seamless waterproofing membrane on the exterior of the structure.

Volclay Panels are special 4-ft by 4-ft corrugated kraft boards that contain 1.0-lb. of sodium bentonite per square foot in the flutes of the board. Since its introduction, more than one-half billion square feet have been successfully installed on thousands of projects worldwide.

Today, two different Volclay Panel types are available: Volclay Type 1 Panel and Volclay Type 1-C Panel. Both are typically used to waterproof cast-in-place concrete backfilled foundation walls. The Type 1-C Panel is the standard 4-ft by 4-ft panel that features a temporary, water-resistant coating on one-side. The special coating inhibits premature hydration of the sodium bentonite from inclement weather prior to backfilling. Once backfilled, the coated panel will hydrate normally, forming a monolithic waterproofing membrane.

Volclay Panels are typically installed by a single worker using a powder-actuated fastening tool directly onto the concrete foundation wall as soon as the forms are removed. And because they do not require any primers or adhesives, Volclay Panels can be installed in freezing temperatures or to damp surfaces.

Volclay Panels offer a reliable, low cost means of providing a waterproofing system that is both effective and environmentally sensitive.

Panel Size and Packaging: Both Volclay Type 1 and Type 1-C Panels are supplied in 4-ft. by 4-ft. (1.2 m x 1.2 m) panels each containing one pound per square foot of Volclay sodium bentonite. Each pallet contains 125 panels.
