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
