Basement Slab Lifting

Lifting a sunken basement slab in surrey, bc.


Sunken floors do not pass inspection. If you are wanting to sell or list your home, make sure you get the full value and piece of mind by fixing the concrete before you sell. In most cases, it will take a day and you can resume business as usual. Don’t wait until the house is on the market before you fix your broken home, enjoy it now!



The home owner had put off repairs for a while knowing that the floors in the kitchen, bedroom, and living room have sunken up to 3 inches. True Level was able to assess the area, and provide a cost-effective and permanent solution to lift and level the floors.

Signs of settlement include:

  • Cracks in the drywall
  • Door frames cracked
  • Visible sunken floor
  • Kitchen appliances off level
  • Gaps under baseboard.

  • Why has it settled
  • How True Level fixes the problem


The solution was to install PolyLevel on the entire lower floor of the home. PolyLevel works in a few different steps. Since this home was equipped with in-floor radiant heating, True Level did not want to drill through a pipe and cause damage. The team surveyed the concrete with a thermal camera that showed exactly where the lines were in order to avoid them. The following steps are outlined here:


  1. Drill holes where PolyLevel is to be installed
  2. Inject PolyLevel to fill all voids and lift settled concrete
  3. Patch holes


It’s important to know how PolyLevel works. The Poly is injected through a port and enters under the slab in a fluid state. Once under the slab, the PolyLevel fills all voids and begins to expand. Our skilled technicians know where and how much to add, ensuring that the concrete slab gets lifted with precision. Once injected and after lifting, the PolyLevel becomes very hard and strong, securing and stabilizing the slab better than any other alternative. The PolyLevel foam has now fully lifted, void filled, and insulated the interior slab producing a safer and more secure home.
