Process

Poly-Lifting

Polyurethane lifting uses a two part expanding polymer foam. The process to raise the concrete by foam injection requires a small hole, approximately 5/8” in diameter, drilled through the slab. The polyurethane is then injected under the slab and into the soil, which then expands, filling in all the voided areas, and raises the concrete. The material for this process is very dense, and only weighs approximately 2 lbs per cubic foot.

BENEFITS FROM POLYURETHANE FOAM INJECTION INCLUDE:

  • Seeks out weak soils, and during expansion, creates a strong, more dense, sub-base
  • The material will take the path of least resistance, and will fill in all voided areas
  • The foam is not weakened by moisture
  • Will retain its cured shape and form, reducing the possibility of forming new voids or further settlement
  • Completely cures within 15 minutes
  • Very strong, dense, and lightweight
  • Requires much smaller and fewer holes
