Crack Injection
Foundation Crack Injection Services | Stop Leaks at the Source
A crack in your foundation wall may seem minor, but even a hairline crack can allow significant water intrusion over time, especially during periods of heavy rain or snowmelt. Crack injection is a precise, permanent repair method that seals foundation cracks from the inside, stopping water infiltration and restoring the structural integrity of the wall. Keystone Foundation Repair performs polyurethane and epoxy crack injections for homeowners and commercial clients throughout our service area.
Polyurethane vs. Epoxy Crack Injection: What’s the Difference?
The two most common materials used for crack injection are polyurethane foam and epoxy resin, and the right choice depends on the nature and purpose of the repair:
- Polyurethane foam injection is flexible, fast-expanding, and ideal for active water leaks. It expands as it contacts moisture, filling the crack completely and creating a watertight seal. Best for cracks where water is currently entering.
- Epoxy injection is a rigid, structural adhesive that bonds the two sides of the crack together with a strength that can exceed the original concrete. Best for dry cracks where structural restoration is the primary goal.
Keystone Foundation Repair’s specialists will evaluate your crack, its width, depth, moisture level, and any active water flow, and select the appropriate injection material for a lasting, reliable repair.

Is Crack Injection a Permanent Fix?
Crack injection is a permanent and highly effective solution for non-structural cracks caused by concrete shrinkage, minor settlement, or hydrostatic pressure, the most common types of cracks found in poured concrete foundations. The injected material bonds to the concrete and fills the crack through its full depth, eliminating the water pathway.
It’s important to note that crack injection addresses the crack itself, but may not resolve the root cause if significant drainage issues exist. In some cases, Keystone Foundation Repair will recommend crack injection as part of a broader waterproofing strategy that also includes drainage improvements or an interior perimeter system. We’ll always tell you what’s needed and what isn’t.
