One Part Polyurethane Foam Grout
Concrete often cracks. It is inevitably recognized and experienced. Concrete construction requires joints. These joints cause very serious problems of water leakage.
Estofoam PU is able to stop water leakage permanently and it is non toxic when cured.
Estofoam PU is suitable and widely been used to seal water leakage, it is recommended for leakages at:-
Sometimes the concrete surface is hidden under a surface of mineral deposits left from long-term water leakage.
In order to inject the resin into the crack, it is necessary to install injection ports, also called mechanical packers.
The depth of the drill hole should be somewhere close to the centre of structure, if possible.
Place packers in the previously drilled hole, so that the top of the rubber sleeve is below the concrete surface. If the packer can’t be pushed into the hole, tap it in tighten the packer with a wrench as tight as necessary.
In some circumstances, it can be very useful to flush the crack with water to improve the subsequent penetration of the Estofoam PU injection resin into thicker walls.
Choose the proper resin for the correct application. The nature of the crack / joint and the conditions at job site determine the choice of material. Active water flow at a high rate is best stopped by using Estofoam PU.
The packers can be removed within 1 hour.
Tools and equipment just can be clean with thinner immediately after use.
