3/8 inch sized holes are strategically drilled in the affected area based on the location, area and scope of the repair.
A two-part polyurethane mixture is mechanically injected through the holes, utilizing carefully calibrated injection equipment. Underneath the concrete a chemical reaction occurs in which the two components mix to create an expanding foam. The foam fills all voids and stabilizes loose, uncompacted soil while expanding to create the lift. Enough material is injected into the troubled areas until the desired height is achieved and the concrete has returned to its original position.
The holes are filled with a high density cement grout and finished to match the existing concrete. You will have level concrete and won’t even know we were there!
There are several factors to consider when choosing a repair company. There are, however, a few factors that are more important than others.
Is the company you’re using properly licensed and insured in the jurisdiction where the work will be performed?
Are the systems they are using, designed specifically for concrete raising and stabilization applications? Unfortunately, there are a few companies performing this type of work that are not using proper systems.
Have you done your homework? There are several online contractor advocacy websites that provide free, unbiased reviews from customers that have used these companies. In some cases the concrete repair process is not an inexpensive proposition, and you want to make sure that you choose the best service company based on the information that’s available to you.
This is probably our most commonly asked question, and arguably the most important. The only similarity between the foam we use and what comes out of the can is that they are expanding foams. Other than that, they have nothing in common. There are nearly a 1000 different types of expanding foams, and every one serves a different function.
This is a GREEN product. The components used are manufactured with recycled materials and are natural polyols, which are completely non-toxic and environmentally safe. Once the components are mixed, the polyurethane develops an outer skin, like a balloon, to contain the reaction process, which makes it completely inert. There are absolutely no environmental restrictions on our material.
The equipment we use is permanently mounted on our trucks and trailers. The noise they generate is contained, for the most part, to the units. The injection gun used to inject the material under the concrete, makes little to no noise. All in all, compared to many other concrete repair companies, our service is extremely quiet!
Our trucks are parked in the street or right of way and light weight, flexible hose is pulled across the hardscape, directly to the affected areas. At no time will any landscape be accessed or disturbed, making the project minimally invasive and your property undisturbed.
Because polyurethane cures as a solid structure, it doesn’t have the same potential for fracture and failure as does a sandy slurry. Polyurethane is a completely inert, solid material that is impervious to water, chemicals, insects, rodents, ground movement or erosion, and as long as the substrate continues to perform the polyurethane will last forever.
Absolutely! It can, and more than likely it will, especially in exterior environments. Along the gulf coast we deal with highly volatile soil conditions, most areas along the gulf coast have soil with high concentrations of bentonite (clay). Bentonite is highly absorbent and will shrink and swell depending on its moisture content. Depending on the time of year, soil can expand or contract depending on the level of moisture present. The concrete that is sitting on top of the soil is subject to that same movement. It’s important to know that the polymers that we inject do not fail. It is not uncommon for concrete to show signs of settlement up to as much as an inch in the summertime from repairs that were just performed in spring. This is no cause for concern. There’s a very good chance that the concrete will return to original once moisture returns to the soil in the fall and winter. If it looks as though you’ve experienced some settlement a few months after the repair, especially in the summertime, do not be alarmed. Be patient, and wait to see what happens in the fall and winter.
