Hydrophobic Urethane Injection

Cracking is a common issue that occurs with poured foundations. Concrete walls will crack due to the release of water during the curing process (known as shrinkage) or because of settlement. Cracks will commonly be found near breaks in the wall (such as windows and beam pockets) or in the middle of long walls uninterrupted by turns in the wall. These cracks will not automatically leak but often do. Surface repairs with rigid products such as hydraulic cement or epoxy will often fail again within a couple of years. Proper crack repair requires that the cracks be fully filled with either epoxy resin or urethane foam.

The Urethane injection method can also solve other common problems with pipe penetrations that leak. When a pipe is installed through a foundation wall many contractors seal the remaining gaps with cement. This cement shrinks when curing and can eventually provide a means for water to enter the structure. Additionally vibrations and temperature differences in the pipe can also cause separation between the pipe and wall.
