Polyurethane Concrete Lifting
Polyurethane concrete lifting is a method used to lift and support sunken or unstable concrete slabs
by drilling holes and pumping polyurethane material under the concrete slab.
3 Easy Steps:
1. Drill - A 5/8" hole (size of a dime) is drilled through the slab into the subgrade.
2. Pump - An injection gun delivers polyurethane material through the slab in incremental injections for complete control of the process.
3. Patch - After the injection process is complete all holes are patched with a concrete mixture to restore the finish of your concrete.
Polyurethane Foam Can Also Be Used for:
Void Filling: Concrete settling is not the only issue our foams can solve. Voids under slabs are often present in areas where wash out or excessive settling have occurred. This material will weigh on average 15-25 times less than a traditional mudjacking or cementitious grout mix, applying less stress on an already failed subgrade.
The process for void filling is the same as concrete lifting: drilling, port installation, and injecting the material.
Joint/Slab Stabilization: Slab stabilization is often required when slabs lack support, but may or may not be settled. Unstable concrete slabs can crack when loads exceeding its capacity are applied with insufficient support underneith.
This unique foam is specifically designed for joint/slab stabilization applications due to its very long reaction time and minimal expansion strength. It will take longer to expand, allowing for the injected mixture to travel further under the slab before hardening.
A Quicker, More Cost Effective Choice: When compared to concrete replacement, the process of lifting concrete with polyurethane foam is typically about half the cost. It is also exponentially faster than replacing concrete. Repaired areas are ready within minutes to be utilized as they were intended. Many of our repairs take less than 1 hour from start to finish!
