Cetco Waterstop-XP | Expanding Strip Waterstop

Product Data Sheet



Waterstop-XP is a synthetic hydrophilic polymer based strip waterstop that provides a positive seal in concrete construction joints by expanding upon contact with water. The engineered swell of Waterstop-XP forms the positive seal against the concrete surfaces within the concrete joint to stop water ingress in both continuous and intermittent hydrostatic conditions.

Waterstop-XP is specially engineered to provide better performance than conventional swellable waterstops in a wide range of environmental conditions such as low pH and high saline environments. The superior expansion and pliability of Waterstop-XP provides effective crack sealing and void filling capacity. Its unique formulation retains cohesive strength properties at both original and expanded volumes for superiorhydrostatic resistance.
