ULTRASEAL^® Waterproofing Membranes

World-Class Innovation in Active Waterproofing

Exceptional waterproofing performance

Lighter and more impervious than traditional waterproofing products, ULTRASEAL waterproofing membranes combine Advanced Polymer Core (APC) technology layered within a durable geomembrane to provide waterproofing protection for any cast-in-place, below-grade concrete construction, such as:

• Underslab installation, including pile caps and grade beams
• Property line installation, including soldier pile and lagging, metal sheet piling retaining wall, earth formed shotcrete retention wall, and auger cast caisson retention wall
• Backfilled walls, including backfilled wall penetrations, terminations, and masonry block walls

ULTRASEAL waterproofing membranes also outperform other solutions both for precast concrete construction and under contaminated conditions.

With a geomembrane ten times more impermeable than traditional hydrophilic membranes, the swelling action of ULTRASEAL has been proven effective in both hydrostatic and nonhydrostatic conditions, expanding as it absorbs water to seal any small concrete cracks caused by ground settlement or concrete shrinkage.

Easy installation saves you money

ULTRASEAL rolls are lightweight and easy to handle, with exceptional flexibility for maximum conformability when fitting to a structure. Even more, it can be installed directly to green concrete and placed as soon as forms are removed—no need to wait for the concrete to cure—and can be installed without primers or adhesives, even in extreme temperatures. It’s a quicker, easier installation that’s also easy on your budget.

Durable and contaminant resistant

Extremely durable, ULTRASEAL is self-seaming and self-sealing—there’s no worries about the inevitable small tears and punctures that always occur on construction sites. Plus, the APC core is resistant to salt and groundwater contaminants, to further protect the underlying structure.
