Concrete Lifting

 Poly-urethane foam is used for unstable concrete that is shifting and beginning to show signs of failure and breakage caused by water permeation along traverse and longitudinal joints or water is penetrating beneath concrete and washing out sub-base causing voids and lack of support to concrete roadways, sidewalks, or driveways. The Poly-urethane foam is used to lift and level out concrete. Poly-urethane foam is also used for concrete void filling and slab/joint stabilizing. The process is quick allowing for minimal lane closures and disruptions. The foam can be used to lift building structures, oil or densifying and solidifying weak and compromised base soils. The polyurethane foam will never loose density a day will not sink due to its light weight material. Poly-urethane foam can be used to lift or level commercial or residential projects. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 


 


1.First, a series of 5/8" holes are drilled in an off-set pattern.

  

2.A two part resin based specialized poly-urethane foam is injected into each drilled hole leaving time for the foam to expand, making sure to fill all voids until concrete is then lifted back to original height. 

3. Once concrete is preserved, existing voids are perfectly filled and concrete panel is completely supported and undersealed. Solid, dense polyurethane foam material is unaffected by water eliminating future water issues, after work is performed and is complete concrete may be used  immediately. The holes are then filled with a high density cement grout and finished to match the existing concrete.
