Basement Crack Repair Process

Polyurethane Resin Injections

• Holes are drilled alongside the crack every 6 inches from top to bottom.
• The holes are drilled into the wall towards the crack on a 45 degree angle so the drill bit crosses through the crack.
• Injection ports are installed into the holes and Zirc fittings are threaded into the ends
• Using a compressor, a mixture of mild acid & water is flushed through the crack to remove any dust, dirt or minerals cleaning the crack for the resin to adhere to.
• Water is then rinsed through the crack to remove the acid and ensure the foundation crack is clean and wet.
• Hydraulic cement is spread over the face of the basement crack to contain the resin while it expands.
• The resin is then injected into the basement crack from bottom to top.  The water in the crack reacts with the resin causing it to expand up to twenty times.  The resin remains flexible and will move with the foundation
