Voids beneath concrete slabs can be filled with two component polymer foam designed to
work in wet or dry conditions. AP
Lift 430 foam can support up to 7,200 lbs per square foot and will cure to 90% full strength in 15 minutes. (Of the most resilient
concrete slab jacking foams, AP Lift 430 is proven to lift concrete slabs under harsh conditions. This two-component, high-strength, high-density,
hydro-insensitive structural polyurethane foam is the top slab jacking solution for concrete slab foundation repair, soil stabilization, and compaction grouting. AP Lift 430 weighs 2.75 – 3.25 pounds per cubic foot.)
Polyurethane foam conforms to void shape more accurately than cement grout, and -
unlike cement - it doesn't shrink or sink over time.
One of the hidden dangers a warehouse or industrial property owner and their employees
can face is an unstable or sunken slab with a large void underneath. The last thing anyone wants is injury or lawsuit resulting from an un-repaired trip hazard or worse - a complete slab collapse.
Take a good long look at the photo in this blog graphic. This occureed when a forklift carrying a heavy piece of equipment crossed a slab with an un-detected void underneath. Luckily, no one was
injured. These voids can be caused by several different causes but there is only a handfull of solutions. The most effective and most cost effective at the same time would be to; have structural foam
injected into cavity filling the void and raising the sunken concrete back to level. These polymers can restablize the surrounding soils.
If water erosion was the cause of the issue, Level Home also offers a wide variety of
waterproofing chemical grout techniques and drainage systems that can stop the water before it ever becomes a problem to your residential or commercial structure!
How Do I Know My Soil Is Unstable??
Unstable soils can have a variety of effects on a structure or concrete slabs of
anykind. If you notice concrete sinking or cracking, these are good indications the underlying soils are not supporting the weight of the concrete. When structures show signs of movement in exterior
siding or interior drywall; these are also signs the soil underneath is not adequate for the weight of structure. Sinking steps, sidewalks, driveways, retaining walls, and/or just about anything that
can sink into the ground. With Polyurethane Foam Injection Level Home is able to raise all of the above mentioned in addition to stabilizing the underlying soils for generations to come! Get a Free
