Foundation Crack Injection & Waterproofin

Foundation Crack Repair

We repair foundation cracks using high-performance polyurethane injection, a flexible expanding resin designed specifically to stop active water infiltration. The polyurethane penetrates deep into the crack, expands to fill voids, and creates a permanent watertight seal that adapts to minor foundation movement.

To reinforce the repair, we apply a BlueSkin waterproof membrane directly over the treated area, followed by a Delta MS membrane to provide additional drainage and reduce hydrostatic pressure against the foundation wall. If the crack is bigger than 1/8 inch we will need to bolt a steel plate at an extra charge

This layered system ensures:

  • Complete crack sealing from within
  • Exterior waterproofing protection
  • Improved drainage and foundation wall protection

All crack injection work is fully guaranteed, and our warranty is transferable if you sell your home, adding long-term value and peace of mind for both you and future buyers.
