Slab Lifting



In our last Poly-Blog we hi-lited applications in the use of polyurethane as a void-filling material. In this Poly-Blog we will address applications relating to concrete settlement and slab-lifting applications.

  • Bridge approaches
  • Concrete On-Off ramps
  • Settled concrete pavements
  • Concrete runways & tarmacs
  • Differentially settled revetment
  • Industrial/commercial walks
  • Office, commercial settled floors
  • Manufacturing plant floors
  • Warehouse floors
  • Concrete paved parking lots
  • Docks & wharves
  • Pre-cast catch basins
  • Slab-on-grade foundations
  • Rafted foundations
  • Swimming pool decks & aprons
  • Garage pads
  • Driveways
  • Basement floors
  • Walks
  • Patios
  • Steps
  • Any non-structural slab-on-grade concrete structure that has experienced settlement



I’d be happy to submit the following testimonial. I hope it is OK for your use.

I recently had some slab lifting performed by your firm. The first project was a slab that had sunk in the corner of a large meeting room at my church. The corner had sunk about 4 inches and we needed it raised so that we could put tile on it and open the room for use. Your crew arrived about 9:00 am and by 10:00 am it was back where it was when it was built. The slab is now ready for finishing.

The second project was my concrete driveway and walk which had sunk over the last 20 years. The driveway had one section which had sunk one inch when compared to the slabs around it and it was a danger for people walking on it. The driveway has sunk about 3 inches right in front of the garage due to poor compaction by the builder. My walk had sunk about 5 inches right by my front porch making it difficult for our aged parents to climb up to the porch. I witnessed the raising of the driveway and sidewalk to their originally constructed levels and was amazed at the care and professionalism of your staff. Everything was done in two hours and is now back to where it was 20 years ago.

A great job well done!
