Concrete Repair and Rehabilitation

Joint Stabilization for Concrete Floor Slabs

Joint Stabilization:  Concrete floors are intentionally saw cut shortly after initial construction.   The series of cuts create "control joint/cold joints" which separates a large concrete floor into smaller square-sized pieces.   When not properly constructed, the smaller concrete squares can warp slightly.  When driven over by heavy forklifts, warped floors can bend at the construction joints, eventually breaking off and creating a disruption in the floor surface.    

Polyurethane Foam Injections provide a low-impact and reliable means for stabilizing loose concrete joints.   The urethane work can be done around existing business operations and quickly repairs the floor.  Advantages of polyurethane foam include:

  • Faster Joint Repairs: Polyurethane injection work rapidly progresses once the crew and equipment is mobilized on site.  Many joint stabilization projects can take between a few minutes to a few days to complete.   
  • Fast Set-Up Time: Polyurethane generally reaches ninety percent strength within 15 minutes from initial injection. This benefits is greatly realized for sites that experience heavy traffic load, especially for warehouse floors and concrete roads. Once an unstable joint has been treated with polyurethane, it can be driven on almost immediately.
  • Less Impact: High density polyurethane foam requires very little clean-up after the work is complete.  Existing operations are minimally affected by the work.  Furthermore, the process does not require an area to clean out equipment.  
  • High-Strength: Polyurethane grout can achieve compressive strengths in excess of 100 psi within minutes, providing long-term stability for stabilizing concrete floor joints.
