What the Experts Say About Raising Concrete with Foam

    1. James Warner (Civil Engineer, Guest Lecturer at the School of Mines, and internationally recognized expert in the concrete leveling field), writes in his textbook, Practical Handbook of Grouting: Soil, Rock, and Structures, “However, [there] are several limitations, the greatest of which is probable lack of complete filling of the cavity. Because the injected material [foam] reacts and reaches its maximum volume in increments shortly following injection, significant voids remain after treatment.  This was found to be the case when a bridge approach slab near the Denver airport that had been so treated [with foam] continued to settle and was subsequently removed.  The foam grout was observed to have developed into pedestals at the drill holes, leaving a large portion of the total area untreated.

The Alternative – AAA Concrete Raising Company

AAA uses a traditional sand slurry mix which is capable of fully filling the voids under a slab. AAA brings a semi truck to each job site, which carries approximately twice the material as its next closest competitor. This insures they will have enough material to completely fill all the voids under a slab.

The Two Vital Steps in Slab Jacking:

1. Raise concrete to proper elevation.

2. Completely fill voids under the slab in order to stabilize it.

These reasons are why AAA Concrete Raising will never use polyurethane foam to raise your concrete.  We are the only company in Denver with a semi truck, which carries up to twice as much material as our closest competitor, giving us peace of mind that we will always have enough material to fill all of your voids.  We believe this is one reason AAA Concrete Raising has been the #1 concrete raising company in Denver for over 25 years.

Our Clients Agree

“Good people, job well done. They did everything just as they committed. Left the site clean and raised the concrete right to its original position. I will definitely use them again if the need arises.”

Neil P.

“The job was scheduled and completed on time and in a very professional manner. The “mud jacking” really worked, our patio is now level and no water should collect. I would recommend AAA to anyone who wants to save approximately 50% over replacement.”
