Foundation Repair / Epoxy Crack Injection for Foundations
Epoxy Crack Injection for Foundations in San Antonio, TX
Seal structural cracks with high-strength epoxy to prevent water intrusion and restore foundation integrity.
A visible crack in a foundation wall or floor that lets water seep in after rain is a common sign of a structural crack. San Antonio's expansive clay soils swell when wet and shrink during hot, dry periods, stressing the concrete. Homeowners may notice dampness, musty smells, or increased pest activity near the crack, indicating that the opening is allowing water and air into the home.
First, we inspect the crack to record its size and check for active water entry. The crack is then cleaned with pressurized water or a vacuum to remove dirt and loose material. We attach injection ports along the crack, seal the surface with a fast-setting epoxy paste, and pump a two-component structural epoxy into the crack under pressure. The resin fills the void, bonds to the concrete, and hardens in a few hours, restoring the wall's strength.
Cost depends on crack length, depth, and the volume of epoxy required, plus site accessibility. San Antonio typically does not require a permit for routine crack sealing, but any work that changes the structural load path may need a city inspection. Temperature affects epoxy cure; ideal range is 50°F-90°F. Extreme heat speeds curing, reducing working time, while cold slows it. If water is already entering, prompt repair prevents mold and additional damage, which can increase overall cost and urgency.

Common questions
How long does epoxy injection last?
When properly installed, epoxy forms a permanent bond that resists water and soil pressure, often outlasting the concrete itself.
Can I do epoxy injection myself?
DIY kits are available, but professional injection ensures the resin reaches the full depth of the crack and bonds correctly.
