Volclay Swelltite®
Product Description
Dual Membrane Waterproofing Protection
Introduced back in 1987, Volclay Swelltite was the
first bentonite waterproofing membrane designed for split-slab deck and
plaza construction. Swelltite combines the natural waterproofing
abilities of Volclay sodium bentonite with a high-strength geomembrane
liner for tensile strength and puncture resistance.
Volclay Swelltite is a true advancement in
waterproofing technology. Unlike other adhered membrane systems which
require near-perfect installation, Swelltite’s active bentonite
compound can expand to seal small installation imperfections or
punctures in the membrane. Swelltite is manufactured at a factory
controlled thickness of 90-mils (2.3 mm) assuring the specifier,
contractor, and owner of consistent material application. This
engineered composite consists of a white 12-mil polyethylene
geomembrane liner and 78-mils of bentonite compound with a clear
release film applied over the bentonite compound. Swelltite contains
virtually zero VOC, can be installed in almost any weather condition to
green concrete, and most importantly, has proven effective on thousands
of projects for nearly 20 years.
Swelltite’s bentonite compound layer works
by forming a dense, impervious waterproofing membrane upon hydration
with water. But for the bentonite compound to activate, the water must
first circumvent the polyethylene liner component, thus making
Swelltite a true duel waterproofing membrane. The swelling action of
the bentonite compound layer can seal small punctures and small
concrete shrinkage cracks, a problem over which conventional adhered
sheet membranes have no control.
Swelltite is easy to install. It can be
applied in all weather conditions to green concrete with mechanical
fasteners or a water-based adhesive. Swelltite is conveniently packaged
in easy to handle 40 inch wide rolls that are simply installed with the
edges overlapped and Seamtape applied. And the tough geomembrane liner
eliminates the need for protection board for most installations.
Applications include split-slab deck and
plaza construction, backfilled concrete foundation walls, masonry block
foundation walls, and tunnels. Interior split-slab applications include
kitchens, laboratories, and bath areas. Swelltite, combined with a thin
layer of StrataSeal or LDC60 has proven to be a unique waterproofing
system for thin slabs poured over plywood decking, such as common walk
areas in Condo construction.
Proven quality and ease of installation
have made Swelltite a market leader in the waterproofing industry. Over
50 million square feet of Swelltite have been installed worldwide on
projects such as airports, commercial offices, parking structures, and
transportation tunnels.
Roll Size and Packaging: Swelltite is
supplied in 40” wide by 37’ 9” long (1.02 m x 11.5 m) rolls for 125
square feet (11.5 sq. m) per roll. Each pallet contains 25 rolls.
