Our polyurethane foam injection process accommodates a broad range of applications within the commercial concrete services. Many of those applications are seen in the commercial industry, including warehouse floor repair. Our state of the art equipment is capable of injecting many different types of polyurethane foam, which accommodates the type of repair needed. We provide foams that are very aggressive in the expanding process, which are great for lifting and leveling concrete, or we have foams that are slow reacting, which are great for void filling and undersealing.

The commercial industry uses our polyurethane foam for the following repairs:

Void Filling and Undersealing: 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 has occurred.  When soils become unstable (many soils have a lot of movement, due to ever changing temperatures and moisture along with poor compaction) voids appear underneath the slab of concrete. Our method of void filling will prevent the slab from failing, and will provide a superior sub-base to the concrete. The foam will repell any water, will not change its shape or form, and will solidify any loose soils, allowing the concrete to be stabilized from potential failure.

Concrete Raising: If you have a concrete slab that has settled PolyRaise can repair it and help you maintain a safer work environment for your employees. Concrete lifting requires a small 5/8″ hole to be drilled through the concrete. A polyurethane foam is then injected through the hole, underneath the concrete slab. The foam will solidify any loose soils, fill in the voided areas, then lift and level the concrete slab. Concrete lifting is commonly used on warehouse floors, sidewalks and walkways, front entrances to buildings, indoor concrete. Our method is fast, efficient, and the foam is very lightweight, yet strong and durable.

Heavy Equipment Stabilization: Heavy machinery, such as forklifts, may cause the concrete to either change its shape (curl), or cause the soils to become loose or unstable, from the vibration of the equipment. This will result in unwanted movement of the slab (usually a rocking), causing annoying and disruptive noises. Our polyurethane foam injection will stabilize the slabs, deterring the movement of the concrete.

Joint/Slab Stabilization: Concrete slab stabilization is often required when concrete slabs lack support, but may or may not be settled. Concrete slabs can crack when loads exceeding its capacity are applied. Slab/joint stabilization applications require the voids to be filled to eliminate movement and offer support. This type of 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 better coverage under the slab or down a joint.

Concrete Raising for Apartment Complexes, Businesses, City Facilities, etc.: When you have uneven sidewalks, stoops, and patios, you introduce the possibility for annoyed tenants and customers, but also the possibility for injury. The American Disability Act requires that walk ways that have more than ¼” drop be repaired or replaced.

Concrete Raising vs. Concrete Replacement
If you have concrete slabs that have failed, then you should take these
points listed above into consideration when evaluating your options to resolve the issue.
