Detailed Procedures in Concrete Leveling

Step-by-Step Guide to Slabjacking

Slabjacking, a recognized concrete leveling method, efficiently corrects the position of hollow concrete slabs by lifting them back to their original elevation. The procedure begins by strategically drilling holes into the slab to facilitate the injection of a stabilizing mixture.

  • Drilling Holes: Carefully place holes in the concrete slab to maximize lift and stability.
  • Injecting Mixture: Pump a mixture of water, sand, cement, and soil through the holes to raise the slab.
  • Filling the Void: The injected material fills the void beneath the slab, providing necessary support.
  • Sealing and Smoothing: After the lift, the holes are patched with concrete, and the surface is smoothed to blend seamlessly with the surrounding area.

This traditional method of concrete repair and leveling is prized for its affordability and minimal disruption, making it a preferred choice for commercial projects.

Executing Polyurethane Foam Injection

The execution of polyurethane foam injection begins with a similar initial step: drilling small holes into the designated concrete areas.
