Soil Stabilization

This process describes altering soils to enhance their physical properties to help make them stronger, and to improve its load-bearing capacity to prevent settlement or sinking of concrete slabs or foundations. The process can be used on many different types of soil conditions, including expansive clays and even granular materials. The process can be completed using many different techniques, but at Don Kennedy and Sons, we make use of a technique known as deep injection with polyurethane concrete raising.

Polyurethane Concrete Raising

Often times, this process is also referred to as mudjacking or slabjacking, but they refer to the same technique. Unlike most contractors who make use of a messy concrete slurry mix, our team uses a special polyurethane foaming material that is much stronger and less messy. It also has many favorable qualities, including the fact that it cures and hardens in roughly 15-30 minutes, after which, it can be walked over or driven on like normal again. It also is able to fill up all the nooks and crannies of a space, whereas concrete slurry might not be able to get into these tight areas.

The Process

For concrete raising, the following will take place:

The surface of the damaged slab will be cleaned off so that no dirt or debris get inside during the repair. Next, tiny holes are drilled into the slab and this is where the polyurethane foam will go. The foaming material is inserted, and it quickly fills up the entire void beneath the sinking surface. This will help to raise and lift the slab back into place where it needs to be. Finally, the holes will be filled in and patched over so that they match with the rest of the surface(s) surrounding it.

Polyurethane Foam Can Also Be Used For

Void Filling

Whenever a slab or foundation has problems with washout beneath it because of erosion or excessive rainfall, the foaming material can be used to fill the area and lessen the amount of stress felt by the surface above. The entire process can be completed quickly and with minimal disturbance to your property.

Foundation Stabilization

This process can also be used when a foundation is weak and lacking support because of weakened soils underneath and surrounding it. The foaming material we use will be able to strengthen the base of a home without having to dig it up to replace certain areas or walls.
