Geotechnical Polyurethane Foam Concrete Lifting in VA

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.

Injection holes are strategically drilled into the concrete slab(s) that requires lifting. The equipment is contained in a trailer rig with a long hose capable of reaching direct to the concrete slab location. Polyurethane foam is then injected under the slab filling voids, and raising it to the correct level.

After the injection is completed, the hole is patched with polymer concrete or cement. The concrete slab is repaired and for immediate use. The concrete repair typically takes a 1-2 hours based on the scope of your project. Most jobs can be done in one day.

Polyurethane concrete raising achieves the same results as traditional mudjacking, but with a lightweight material that requires smaller and fewer injection holes.  Also known as foam lifting, polyurethane concrete raising is the latest and greatest concrete repair method available.

Cost-effective

Polyurethane foam concrete raising is a cost-effective alternative to replacing concrete. Concrete raising can usually be done for less than half the cost of pouring new concrete. However, the savings may be even greater, since when concrete raising the costs of demolition, removal, and landscaping are eliminated.

Polyurethane foam concrete lifting and stabilization avoid costly tear out and disruptive replacement of the slab. This allows the surrounding area to remain in use or service even during the project with minimal downtime, if any.

Quick Cure Time

Polyurethane typically cures in minutes after injection allowing areas to be fully available in minutes not days.

Benefits and Advantages of Concrete Lifting and Foam Jacking using Polyurethane Foam

  • Simple Application
    Since the foam cures in minutes—most solutions exhibit 90% of full compression strength after 15 minutes—large surface areas can be lifted and returned to service immediately during the application. This allows for swift construction and minimal waste.
  • Lower Costs
    The ease of application contributes to less time working, as does the fact that many of our geotechnical foam solutions can be applied by a two-man crew. These factors all translate to fewer paid man hours, and lower overall job costs.
  • Exotherm-Free Processing
    Our geotechnical foam solutions are designed to be built up in great lift thickness without scorching or foam splitting. During application, our systems have low exotherm heat transfer, which eliminates additional spray passes and ensures quick construction.
  • Moisture-Tolerant and Resistant
    Though our solutions are injected into wet areas, they will maintain their physical characteristics during reaction and expansion. Plus, the high-density, closed-cell nature of geotechnical foam makes them resistant to water penetration
  • Exceptional Inter-Layer Adhesion
    Due to high structural compressive strength providing strong inter-layer adhesion, our solutions ensure a strong monolithic barrier, one that outperforms sand bags. Profoam’s geotechnical foam systems don’t shift and settle afterwards, which means long-term erosion issues are reduced.
  • Extremely Conformable
    During the injection process, geotechnical foam will flow freely into cracks and voids, ultimately expanding to its final in-place density—which is normally greater than its free-rise density. Free-rise density is determined without any loads or restrictions placed on the geotechnical foam.
  • Environmentally Responsible
    Formulated with an environmentally responsible non-ozone depleting blowing agent, our solutions offer a trouble-free alternative that can last a lifetime—and that makes no additional use of our natural resources.
