WPA PUR GT103

WPA PUR GT103 is a single-component polyurethane injection resin used to seal gushing leaks, including wide gaps in concrete, where the structure is not subject to movement. This hydrophobic, low viscosity polyurethane reacts with water and expands to form a closed cell, watertight, rigid foam.

​

Field of application:​

• Shut off water leaks in concrete, brickwork, and sewers where movement and settlement may occur.

• Water cut-off of water leaks in foundations such as diaphragm walls, piling sheets and secant piles.

• Sealing water-carrying cracks and joints in tunnel segments.

​

Features:

• Single component

• The closed-cell structure of cured polyurethane ensures permanent flexible sealing of cracks and joints.

• Variable reaction times

• Up to 30x expansion (unconfined)

• Cured polyurethane is flexible, shrink-free and exhibits good chemical resistance (contact our Technical Service for chemical resistance).

• Cured polyurethane is harmless for the environment and resistant to biological attacks.
