Concrete Lifting Calgary – Slab Jacking, Void Fill

Offered By:

what is slab jacking?

Preferred by many contractors, the Ener-Spray method offers the same results as traditional concrete raising, stabilization, and void filling but with new and improved characteristics. Ener-Spray’s high-density polyurethane foam injection is used for concrete lifting, stabilization and void filling applications.

Some of the highlights are:

  • Cost Effective: costs less than replacing your concrete
  • Quick Cure Time: our foam typically cures 15 minutes after injection – a massive benefit to those needing shorter downtime to the affected areas.
  • Hydrophobic:  no issues when used in wet applications. The same chemical reaction will happen in or out of water.
  • Moisture Barrier: resistant to water penetration and will seal the concrete from the underside.
  • Inert and Stable: Does not change with time, moisture or the soil and will not leech harmful chemicals into the ground.
  • Lightweight: the foam typically weighs between 2.5 lbs per cubic foot to 6 lbs per cubic foot, depending on application and requirements. It supports significant loads and has a very high compressive strength. Unlike mud-jacking material weighing 120 lbs per cubic foot, the slab-lifting foam will not burden the soil. 
  • Small injection Holes: The 5/8” hole is significantly smaller than traditional mud-jacking, which uses a 1 5/8” hole. Ener-Spray’s slab lifting and void filling system use fewer holes than conventional methods.

Depending on the application, there are several material options.

  • Residential Application: High-density polyurethane foam for concrete lifting and stabilization. The reasons are to avoid costly removal and replacement of driveways, basement slabs, garage slabs and sidewalks.
  • Commercial Application: Ener-Spray has worked on various big and small projects. We have worked for General Contractors, Property Managers, and Building Owners. Some examples of uses are Warehouse Floors, Bridge Approaches, Man Holes, Multi Family Complexes, Ramps, Courtyards, and Slab Stabilization for production equipment.
  • Industrial Applications: Ener-Spray has worked on many industrial projects ranging from large to small scale. We have worked for Husky Oil, Trans Alta Hydro Electric Dams and everything in between. Some examples of uses are tank pads, concrete secondary containment, plant floors, sumps, void fill around underground tanks/pipes, spillways, pump stations, ditch fill, trench breakers/pipeline pillows and soil stabilization.

We offer a 5-year warranty on all completed work.
