COREFLEX® 60

COREFLEX Consists of a thermoplastic membrane integrally bonded to a self-healing Active Polymer Core (APC). This combination of passive and active barrier technologies, along with fully welded seams, ensures superior waterproofing protection.

ENVIROSHEET

A self-adhering composite sheet waterproofing membrane, ENVIROSHEET consists of 56-mils of rubberized asphalt and a 4-mil cross-laminated, polyethylene carrier film. The two components are laminated together to produce an extremely tough waterproofing barrier.

HYDROFIX

A 100% Solids Fluid-Applied, HYDROFIX is a single component waterproofing system. Its fluid application allows it to be installed at difficult areas such as around multiple pipe penetrations and over irregular substrates and cures to form a seamless membrane that is positively bonded to the substrate.

LDC 60

A elastomeric waterproof membrane, LDC 60 cures to form a seamless barrier that forms tenacious bond to concrete to prevent lateral water migration. The inherent toughness and elasticity of LDC 60 enables it to bridge small structural or shrinkage cracks which may develop in the substrate.

STRATASEAL HR®

A hot-applied rubberized asphalt membrane, STRATASEAL HR is ideal for protected roof and split-slab deck waterproofing applications. Its a 100% solids thermoplastic product that is flexible as well as self-sealing. STRATASEAL HR is ready for use and requires no set-up.

SWELLTITE®

A highly effective waterproofing membrane, SWELLTITE® consists of a sodium bentonite compound integrally bonded to a geomembrane liner. This composite combines the active waterproofing benefits of sodium bentonite with the strength and durability of a thick geomembrane liner.

T-SERIES FOR TUNNELS

The T-series thermoplastic waterproofing membranes are specifically designed for tunnel projects. They have excellent puncture and elongation properties and are resistant to root penetration and micro-organisms.

ULTRASEAL®

Consisting of an advanced Active Polyer Core (APC), ULTRASEAL is engineered to provide high-performance waterproofing protection for foundation applications. ULTRASEAL is 10 times less permeable and more chemically resistant than traditional hydrophilic waterproofing membranes.

ULTRASEAL® XP

Featuring XP technology, the latest innovation in active waterproofing, ULTRASEAL XP provides exceptional performance in a wide range of ground contaminates. Proven effective in both hydrostatic and non-hydrostatic conditions, the self-sealing ability of ULTRASEAL XP seals minor cuts or damage to the membrane.

VOLTEX®

Voltex® is a proven waterproofing membrane ideal for vertical and horizontal foundation surfaces. Voltex incorporates the high-swelling and self-sealing properties of VOLCLAY® sodium bentonite to form a monolithic, low permeable membrane to protect the structure from water ingress.

VOLTEX® DS

A bentonite-geotextile waterproofing membrane with Integrated Polyethylene Liner, VOLTEX® DS is comprised of two high strength geotextiles. The two geotextiles are interlocked by a patented needle-punching process which assures a consistent application of material.

VOLTEX® DSCR

VOLTEX DSCR is a highly effective waterproofing composite of high strength geotextiles,1.10 pounds of contaminant resistant sodium bentonite per square foot, and a integrally bonded polyethylene liner. The high swelling, low permeable, contaminant resistant sodium bentonite is encapsulated between the two geotextiles.

WATERSTOP RX

An active, flexible strip concrete construction joint waterstop, WATERSTOP-RX provides a strong positive seal by expanding upon contact with water. Proven effective on projects worldwide for over 20 years, Waterstop-RX is designed for both continuous and intermittent hydrostatic conditions. WATERSTOP-RX is available in multiple configurations.

WATERSTOP XP

The next generation of waterstop that expands upon contact with water to form a positive seal to stop water ingress through cast-in-place concrete construction joints and around pipe penetrations. Through the use of the patented XP technology, WATERSTOP® XP is proven effective in a wide range of contaminated environments.
