Crack Injection

Crack injection and system flush ports work hand-in-hand to eliminate active water entry while ensuring the long-term maintenance of an interior drainage system. When external hydrostatic pressure forces groundwater through porous concrete, foundation cracks form and act as direct pathways for basement flooding. Crack injection directly addresses this structural vulnerability. We mount surface ports along the fracture and inject a flexible, expanding polyurethane or high-strength epoxy resin. The material expands to fill the entire void from inside to out, permanently bonding the concrete, stabilizing the wall, and blocking groundwater intrusion.

However, water entry can also wash fine soil sediment and iron algae into sub-floor perimeter drains over time. This is where system flush ports (or maintenance cleanouts) become vital. Strategically integrated into the drainage channel at floor level, these accessible ports allow homeowners or technicians to perform routine maintenance, flood-test the system, and clear out sediment blockages without tearing up the concrete floor. Together, injection stops immediate wall leaks, while flush ports guarantee the sub-floor drainage system flows freely to the sump pump permanently
