Volclay® Panels
Product Description
 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.
