Foundation Crack Repair

Foundation cracks are the most common foundation problem and the most misunderstood. Most cracks are not structural threats on their own, but every crack lets water in. Polyurethane injection seals active leaks. Epoxy injection restores structural integrity for hairline cracks under load. The right choice depends on whether the crack is structural or non-structural.

Common symptoms

If you're seeing any of these, it's worth a closer look:

  • Visible vertical or diagonal cracks in foundation walls
  • Horizontal cracks (often more serious — possible bowing)
  • Water seeping through walls or at floor-wall joint
  • Efflorescence (white mineral deposits)
  • Stair-step cracks in brick or block foundations

How it works

  1. 1Inspection: identify the crack type and underlying cause
  2. 2Surface prep: clean and route the crack for injection
  3. 3Polyurethane or epoxy injection at low pressure
  4. 4Final surface finish
