Interior Crack Repairs

At ULB-DRY Waterproofing, we know how to handle interior crack repairs. We service two different types of interior cracks — dirty (previously repaired) and clean (never touched, or virgin). 

Here is the process for interior crack repairs:

  • The surface of the crack is cleaned of all loose dirt and other contaminants.
  • Series of small plastic ports are set directly over the void and held in place with a two-part epoxy mastic.
  • While waiting for the surface patch to dry the exterior area is checked, and any portion of the crack above grade is sealed to help insure the resin is confined to the wall cavity.
  • Once the surface patch has cured, an epoxy/urethane resin is injected into the wall crack, starting at the port closest to the floor level.
  • The injection will continue to this port until the material is forced upward and flows out of the port above.
  • The injection port is capped towards the top of the foundation until the resin is noted over the upper part of the foundation.

Now you know how to repair interior wall cracks!
