ULTRASEAL® Advanced APC Waterproofing Technology

Ultraseal is a unique waterproofing membrane that utilizes an advanced Active Polymer Core (APC) technology that is ten times less permeable and more chemically resistant than traditional active waterproofing membranes. Ultraseal combines the APC technology with a strong geomembrane liner for exceptional performance. Ultraseal contains zero VOC, can be installed in almost any weather condition to green concrete and most importantly, has proven effective in both hydrostatic and nonhydrostatic conditions.

Ultraseal works by forming a low permeable membrane upon contact with water. When hydrated, unconfined APC can swell many times its dry volume. When confined by backfill or concrete the swell is controlled, forming a dense, impervious waterproofing membrane. The swelling action of the APC technology resists high levels of groundwater contaminants and can self-seal small concrete cracks caused by ground settlement, concrete shrinkage, or seismic action. Ultraseal forms a strong mechanical bond to concrete when the concrete is poured against the membrane.
