Foundation crack repairs
Foundation crack repairs by polyurethane and epoxy injections
In a natural way, concrete is subject to internal movements (contraction and or shrinkage), and likely to crack. In some cases, the presence of cracking is not a major problem but it is still always prudent to conduct a preventive repair. We must remain vigilant and carefully consider certain types of cracks that may prove to be a sign of a more serious problem.
A crack in a foundation can be passive or active. It is essential to determine which category or cracks we are dealing with before performing any repairs. The cracks due to the removal of concrete, poor initial compaction or premature soil filling around the foundation stabilize after the first few years of initial construction. On the other hand, the cracks caused by an upward movement caused by frost, by a slump, a soil of poor quality or poorly compacted embankment can still be active and get worse. For cracks determined to have active movement, we install reinforcement plates to strengthen and stabilize the crack and prevent possible future movement of the repaired area
