The right fix starts with the right diagnosis

Seal basement cracks before they become bigger problems

Not every basement crack signals a structural problem. Many are shrinkage or settling cracks in poured concrete or block that let water seep through under pressure. Injection repair fills the crack with epoxy or flexible polyurethane, sealing it from the inside so water has nowhere left to go.

Common problems we solve

  • Hairline to moderate cracks in poured concrete or block walls
  • Active water seepage or dripping through a visible crack
  • Cracks that widen or leak more after heavy rain
  • Uncertainty about whether a crack is cosmetic or structural

Benefits of a properly designed solution

Injection seals the full crack depth

Epoxy or polyurethane fills the crack through its entire depth, not just the visible surface.

Flexible polyurethane for active leaks

Polyurethane expands to seal moving water even in cracks that are actively leaking.

Rigid epoxy for structural bonding

Epoxy is used where the goal is to restore structural bond strength in a non-moving crack.

Diagnosis before repair

We confirm whether a crack is a simple seal-and-fill job or needs structural evaluation first.

Our four-step process

  1. Inspect: Document moisture, drainage, structure, and site conditions.
  2. Explain: Review findings with photos and straightforward priorities.
  3. Install: Complete the agreed scope with careful home protection.
  4. Verify: Test components, clean the work area, and complete a walkthrough.
Common questions

Basement Crack Repair FAQs

How do I know if my crack is structural or just cosmetic?+

Structural cracks are typically wider, stair-stepped in block walls, or accompanied by bowing, uneven doors, or floor movement elsewhere in the home. We assess this during inspection and refer to structural repair if warranted.

What is the difference between epoxy and polyurethane crack injection?+

Epoxy bonds rigidly and restores structural strength to a stable, non-moving crack. Polyurethane stays flexible and is better suited to actively leaking cracks or ones that may move slightly with temperature.

Will crack repair alone stop all basement water issues?+

It stops water entering through that specific crack. If your basement has broader seepage or hydrostatic pressure issues, we may also recommend drainage or waterproofing alongside the crack repair.
