Crack injection involves crack repair and basement waterproofing techniques which are only applicable to poured concrete foundations and structures. Crack injection, or foundation crack injection, is used in the following applications:
• To repair cracks of virtually all sizes in poured concrete foundation walls;
• To permanently repair actively leaking cracks;
• To repair cracks that have been previously repaired by injection or some other basement waterproofing technique; and
• Crack repair in poured concrete structures in general.
Foundation crack injection involves the pressurized injection of either epoxy or polyurethane resin into a foundation crack; these injections are referred to as epoxy crack injection and polyurethane crack injection. The injection pressures ensure that cracks are filled through the entire thickness of a foundation wall which is typically 8" or 20cm thick, thereby effectively eliminating the crack and keeping water on the exterior of the foundation where it belongs so that you no longer have water in your basement. This type of concrete crack repair is all that is needed to accomplish basement waterproofing when a poured concrete crack is leaking, or if there is a concern that an existing crack may leak in the future. Pressurized crack injection is also the most economical means by which to repair a wet, leaky poured concrete basement; in reality, it is rarely necessary to excavate a poured concrete foundation wall.

Given the propensity for the water table to rise significantly during heavy prolonged rains, we disagree with contractors that use the gravel layer beneath your basement floor as a dry well for leaking foundation cracks to drain into.
