PolyRenewal™ Injection Foam

Polyurethane foam injection is both lightweight and durable, and is able to support and lift sunken concrete.

The stability of any concrete surface is dependent on the soils beneath it. The weight of concrete and what it supports, combined with natural soil erosion, can lead to sunken and uneven concrete surfaces. This process affects everything from your driveway and sidewalk to roads and airport runways.

Innovative Basement Authority provides expert concrete repair solutions using the PolyRenewal™ system. PolyRenewal™ is an expanding polyurethane foam that is injected beneath the concrete to fill the gaps caused by soil erosion and raise and stabilize the concrete surface.

PolyRenewal™ geotechnical capabilities:

  • Lift settled slabs and slab foundations
  • Lift sunken sidewalks
  • Strengthen and stabilize loose soil
  • Fill sinkholes and other voids
  • Lift and stabilize roadways and airport runways
  • Repair and stabilize rail beds weakened by soil washouts
  • Treat soil to improve load-bearing characteristics in preconstruction applications

Reasons to choose PolyRenewal™

  • Strong but light: PolyRenewal™ weighs only about 4lbs. per cubic ft., compared to 120lbs. per cubic ft. for standard fill material. PolyRenewal­™’s light weight makes it useful where denser fill material might impose an undesirable load on weak soils. Despite its light weight, PolyRenewal™ can support substantial loads; it typically provides greater lifting power than mudjacking.
  • Waterproof: Once cured, PolyRenewal™ will not wash away. PolyRenewal™’s waterproofing properties can be beneficial in certain applications.
  • Stable and inert: PolyRenewal™ does not react with soil or moisture; it will not leach harmful chemicals into the soil.
  • Quick curing. Downtime is minimized with PolyRenewal™ concrete repair. Full loading of the foundation, roadway, or other structural element can usually happen about 15 minutes after the material is injected.
  • Adjustable: Adjusting the density and expansive force of the 2-part foam affords a wide range of geotechnical uses. Lifting force can be adjusted by fine-tuning the chemical reaction that causes the foam to expand. An experienced applicator can factor not only the weight of the structural element but also soil characteristics and temperature and weather conditions. Special formulations are possible for applications where water must be displaced.
  • Noninvasive: PolyRenewal™ injection equipment isn’t bulky, enabling applicators to access confined areas. When properly injected, PolyRenewal™ is not as messy or disruptive as other slab and foundation-lifting techniques.
