PRESWELL Hydrophilic Waterstop
Hydrophilic Waterstop
Hydrophilic polymer rubber waterstop strip that expands 400–500%
PRESWELL Hydrophilic Waterstop is a vulcanized polymer-based hydrophilic expansion strip designed to prevent water ingress through concrete construction joints.
Manufactured from natural rubber blended with sodium polyacrylate hydrophilic polymers, plasticizers, viscosities and anti-ageing agents, it delivers controlled swelling and recovery expansion performance.Upon contact with water, PRESWELL expands 400–500% of its original volume, forming a compression seal against surrounding concrete.
