Repairing Wall Cracks

A basement with a leaking wall crack is generally caused by concrete shrinkage, foundation movement, or hydrostatic pressure pushed the walls in.. Continued pressures, such as soil contraction and expansion, can cause further foundation cracks and separation.   So a long-term solution is needed -- one that is flexible enough to permanently fix the crack even with continued wall movement.

Gibbons Basement Systems has been repairing foundation cracks with various injection methods for many years. In fact, we were applying polyurethane injection to residential basement wall cracks before anyone had heard of such a thing. Injecting sealant materials into concrete wall cracks was a big breakthrough at the time.

Yet, we have watched and struggled as structural movement, continued shrinkage of the foundation wall, and other factors on new and older homes alike have caused these concrete crack repairs to fail.

Therefore, if your crack repair method is injection alone, the crack will often get larger and re-leak. Soil expansion and contraction causes foundation movement and re-leaking will occur. We searched for a better way and found it -- the FlexiSpan Foundation Wall Crack Repair System patented by Basement Systems. This is a method to permanently fix your wall crack and stop leakage

This process can easily be done in one day and provide a level of protection for those leaking cracks, form ties, and leaking pipe penetrations.
