All You Need To Know About Polyurethane Injections

Why the Need for Polyurethane?

Since the dawn of civilization, soil stabilization has been a concern for those involved in building structures, roads, and bridges.  Even with all the technology we have today, unpredictable weather conditions can produce snow, rain, and severe temperature shifts which can create deep underground expanses such as voids, water pockets, and fissures. Polyurethane injections can help with many of the problems caused by these influences.
Other causes of unstable soil conditions can be attributed to improper soil compaction, soil erosion, and plumbing leaks. These expanses destabilize the structures and foundations which result visibly in cracks, potholes, sinkholes, and damage that can take its toll on private property like homes and structures and public assets like pipelines, roads, sewers, bridges and other structures.

How to Deal with Unstable Soil Conditions

Most work crews attempt to deal with the symptoms by sealing the cracks, filling the potholes, rebuilding the damaged structures, or laying down new asphalt. However, these attempts only mask the underlying problem and the issues will reoccur, requiring the same type of maintenance and repair after each season of extreme weather. The answer is to deal with the issues that are causing the problem: unstable soil conditions.
At Airlift Concrete Experts, LLC we always attempt to deal with the issues that are causing the damage versus only dealing with the symptoms.  Our goal is to provide our customers with quality solutions that solve soil issues directly at their source. We do this primarily by using polyurethane foam that is injected deep into unstable soils. This process offers our customers the most affordable and cost-effective solutions to their structural problems. Alternatives to this method are expensive excavations and removing and replacing the concrete.

Soil Stabilization with Polyurethane Foam

Many people wonder how the process of polyurethane repair works. First, penny size holes are strategically drilled in the affected area based on the location, area, and scope of the repair. Then a two-part polyurethane mixture is mechanically injected through the hole utilizing carefully calibrated injection equipment. Underneath the concrete, a chemical reaction occurs where the two elements mix to create an expanding foam. The foam fills all voids in the surrounding soil and stabilizes loose and non-compacted soil while expanding to create the lift. Enough material is injected into the troubled areas until the desired height is achieved and the concrete has returned to its original place. The holes are then filled with a high-density cement type grout and finished to match the existing concrete. You won’t even know that there was a repair to the concrete.

The Benefits of Polyurethane Foam Injections

  • Polyurethane Deep InjectionThey are strong, lightweight and dense
  • Hole repair is completely concealed and unnoticeable
  • Completely ready for service within 15 minutes of completion
  • Smaller and fewer holes are needed to complete the job
  • The foam will retain its strength and structure, reducing the possibility of new gaps or settlement
  • Once injected into the soil, the foam will find a path to fill in all gaps and voided areas under the concrete created by underground water displacement
  • The foam is not weakened by moisture or chemicals found in soil
  • The foam seeks out weak soils and voids during expansion, creating a strong and denser base
  • Polyurethane foam is environmentally friendly. It is an inert material that is self-contained and does not seep.
