The term “geotechnical” describes the application of technology to engineering problems caused by geological factors. Geotechnical polyurethane foam refers to polyurethane foam (like the spray foam in homes and buildings) that is formulated for residential and commercial geotechnical uses.
One of the leading manufacturers of geotechnical foam in the United States is NCFI, the manufacturer of TerraThane Residential Geotechnical Polyurethane Foam Systems.
Using geotechnical foam is often referred to as “concrete lifting” or “slab jacking” since it’s used for concrete lifting and leveling, foundation repair, infrastructure remediation, and erosion control.
Geotechnical polyurethane foam formulations exhibit almost full compression strength in as little as 15 minutes and its low eco-therm heat transfer during application ensures swift construction and minimal waste.
It’s also moisture tolerant and resistant – the foam maintains its physical characteristics during reaction and expansion. It’s also resistant to water penetration due to being high-density and having a closed-cell molecular structure.
Geotechnical foam systems don’t shift and settle afterwards, which means long-term erosion issues are reduced. During the injection process, geotechnical foam will flow freely into cracks and voids, ultimately expanding to its final in-place density.
Elite Insulation & Concrete Lifting in Broadway, Virginia uses geotechnical polyurethane foam to solve a variety of customers’ problems. Here’s a video showcasing some of their projects.
Most Polyurethane Foam Concrete Lifting, Stabilization and Void Filling projects can be completed quickly and economically with minimal disruption, and one day turnaround and return to service.
More about concrete lifting from Elite Concrete Lifters:
- Cost-effective alternative to replacing concrete
- Can usually be done for less than half the cost of pouring new concrete
- Additional savings since the costs of demolition, removal, and landscaping are eliminated
- Avoids costly tear out and disruptive replacement of the slab
- Surrounding area remains in service even during the project with minimal downtime, if any
