What kind of material is used to lift/raise concrete?

At Richards’ LLC, we use a polyurethane foam to lift and level the existing concrete. The foam is injected as a liquid and then hardens to a rigid foam. The foam will never shrink and will never lose density. The foam material is much lighter than mudjacking materials and requires much smaller and few holes to inject the foam.

How much does concrete lifting cost?

Concrete lifting is usually about 1/2 of cost of replacing the same concrete. Typically, concrete lifting can cost between $2-5/square foot, depending on the amount of polyurethane foam that is needed to raise to the desired level. Factors that contribute to the final price of the project are:

– how far has the slab settled?

– are there voids present?

– do other sections need to be involved in the repair?


Is the polyurethane foam safe?

Richards’ LLC purchases the polyurethane “poly” foam directly from the manufacturer in Manitowoc, Wisconsin. The patented poly foam is manufactured by their in-house chemists and specifically engineered for raising, leveling, and stabilizing concrete. The foam is freshly made when ordered, and shipped directly to us.

The foam is environmentally friendly, consisting of 39-49% renewable and recycled materials, making it the “greenest” poly foam on the market. And, the foam does NOT use toxic chemicals.

So, you say concrete lifting is environmentally friendly?

Yep! As stated before, the foam is environmentally friendly, consisting of 39-49% renewable and recycled materials. This makes the foam we use the “ greenest” poly foam on the market. And, the foam does NOT use toxic chemicals. In addition to using recycled materials, our manufacturer estimates that over 100,000 slabs of concrete have been saved from going to landfills! Imagine, you save money by raising, not replacing, AND it is a way to be GREEN and help the environment! It’s a WIN-WIN!

Is maintenance needed after the lifting?

After Richards’ LLC completes our work, it is the customer’s responsibility to caulk the seams of sections that were repaired, and/or backfill any exposed areas to contain the material. It is important to prevent water from going under the slab as a way to help preserve the repaired slab. The customer can do this by making sure that downspouts are correctly placed to have water running away from your concrete or foundation.

How does Richards’ LLC concrete lifting method with polyurethane foam compare to traditional mudjacking?

Our polyurethane foam material is much lighter than mudjacking materials and requires much smaller and few holes to inject the foam. Richards’ LLC also will not need to drive heavy trucks onto your lawn and landscaping. By using polyurethane foam to raise your concrete, we bring a hose directly from our trailer to the repair site without driving one piece of equipment through your yard.
