Davco® PU Waterstop

A single component low viscosity hydrophobic polyurethane grouting material. When comes in contact with water, the grout expands quickly and cures to form a tough, rigid, closed-cell polyurethane foam that is generally unaffected by corrosive environments. This closed-cell polyurethane foam is designed for cutting off water leaks with high flow rate and/or high pressure. It may also be used to fill large voids such as rock fissures, crushed faults, gravel layers, joints cracks and honeycombs in concrete that are not subject to settlement or movement.

  • New generation resin with improved waterproofing properties.
  • Forms a tough durable, high-strength closed cell foam in cracks or joints.
  • One component, simple to use.
  • Resistant to organic solvents, acids, alkali and micro-organisms
