Unique and innovative, ULTRASEAL® waterproofing membranes meet the toughest waterproofing challenges, even in high-saline and contaminated groundwater conditions.
It’s the state-of-the-art water barrier solution.
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.
ULTRASEAL XP is a composite membrane consisting of an XP technology layer that is integrally bonded to a high-strength geomembrane. This advanced polymer technology provides exceptional performance in a wide range of ground contaminants, including high saline conditions. The durable geomembrane makes ULTRASEAL XP ten times less permeable than traditional hydrophilic membranes. The swelling action of the XP layer can also self-seal small concrete cracks caused by ground settlement and concrete shrinkage while proving effective in both hydrostatic and non-hydrostatic conditions.
