How Polyjacking Works


How Polyjacking Works

Polyjacking is a term used for a method of concrete lifting that involves the use of a poly-foam compound. In this method of concrete lifting an expanding poly-foam compound is injected underneath your sunken concrete slabs at key points to raise it to its proper level and to also provide a deterioration resistant support material underneath the slab. The process is simple and can be completed in under a day depending on the size of the concrete slab that needs to be repaired.

What Can It Be Used To Lift

Because the expanding foam used for the polyjacking method is so strong it can be used to lift any number of concrete slabs. Take a look below to see what applications polyjacking is appropriate for.

  • Patios
  • Driveways
  • Garage Floors
  • Basement Floors
  • Walkways
  • Warehouse Floors
  • Parking Lots
