Several factors can trigger a crack in the foundation. While ground movement can play a role, most of the time it is a drainage problem. The foundations are poorly drained, the soil is saturated with water and a slight movement of the foundation causes cracks in the concrete, they must be repaired quickly as they allow water to enter.
Without a question, polyurethane crack injection is the most widely used waterstopping crack repair process in the world. Polyurethanes are elastomeric and fast-setting, making them ideal for sealing and waterproofing a crack that will move slightly due to seasonal temperature changes.
Epoxy injection is a cost-effective way to repair non-moving cracks in concrete walls, slabs, columns, and piers, restoring the concrete's pre-cracked strength. Epoxy injection structural restoration of concrete is frequently the only alternative to complete replacement. Rebar is protected by epoxy injection, which also prevents water leakage.
