front door step alignment and leveling


We were called by the homeowner of this property in Surrey because the sidewalk leading to the stair in their main entrance had sunk to some degree. The void beneath the stair was a concern for the homeowner, who was worried it could cause further problems besides making the front step uncommonly tall, creating a severe trip hazard. 

He was considering spending money on building a new step to cover the void and shortening the stair, but he found out about Polylevel and asked True Level Concrete to do the job just in time.



Our team of installers arrived on-site, checked the area with the homeowner, and got ready to work! 

First, they started by drilling holes in the concrete slab for the injection ports. Then, they injected PolyLevel foam under the concrete, filling the voids and allowing a controlled lift to close the opening beneath the step. Once the slab was lifted, the installers used Nexus Pro to seal the joints along the grade. They finally cleaned the site and left the front door stair like new.

The homeowner was pretty satisfied with the results and happy that he didn’t choose to pour more concrete into the void.


Here’s the whole process step by step:

  1. Drill holes where PolyLevel is to be installed
  2. Inject PolyLevel to fill all voids and lift settled concrete
  3. Patch holes and seam cracks
  4. Blend seams with the rest of the concrete
  5. Clean site
