Concrete Leveling and Lifting Repair
When injected beneath sunken or uneven foundation slabs, such as sidewalks, driveways, or warehouse floors, the expanding foam fills voids and compacts loose soil, effectively raising and stabilizing the concrete. This process is commonly referred to as “foam jacking” or “polyjacking.”
Concrete lifting foam offers several advantages over traditional methods like mudjacking (using a slurry of cement and soil). These include:
Overall, concrete lifting foam provides an efficient and cost-effective method for repairing and restoring sunken or uneven concrete surfaces.
Lightweight
Polyurethane foam is significantly lighter than the materials used in mudjacking, reducing the load on the underlying soil.
Quick Cure Time
The foam typically cures within minutes, allowing for immediate use of the repaired area.
Minimal Disruption
The injection process requires small holes drilled into the concrete, minimizing disruption to the surface.
Waterproof
Once cured, the foam creates a waterproof barrier, protecting against moisture and preventing future erosion.
Long-lasting
Polyurethane foam is durable and resistant to decay, providing a long-lasting solution to concrete settlement issues.
Concrete Lifting and Leveling
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 resin injection 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 resin injection for 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
Poly-resin injection for 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 resin injection for 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.
Polyurethane typically cures in minutes after injection allowing areas to be fully available in minutes not days.
Benefits and Advantages
Concrete Lifting and Foam Jacking using Poly Resin Injection
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.
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.
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
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.
