Cracking is commonly found in poured foundations. When concrete cures it also generally shrinks and cracks can again appear. The only way to make a permanent cure for the problem is for the foundation to have the cracks fully filled with either epoxy resin or urethane foam. Many contractors seal gaps with cement when installing pipes through a foundation wall. Separation between the pipe and foundation wall caused by vibration or temperature can again allow water to enter.
Cracking commonly occurs with poured foundations. Often concrete basement walls crack due to the release of water during curing or because of settlement. These cracks form commonly around breaks in the wall (such as windows and beam pockets) or in the middle of long walls where there is no interruption turns in the wall. Cracks in basement walls will not automatically leak but sadly they often do. Repairs to the surface with hydraulic cement or epoxy products will often fail again within a couple of years. Proper and permanent concrete crack repair requires that these cracks to be fully filled with either epoxy resin or urethane foam.
Leaky Pipe Penetration
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 basement. Vibrations and temperature differences in the pipe can also cause separation between the pipe and wall creating a gap. Urethane injection can solve this and other common problems.
