Out With the Old (Mudjacking) & In With the New (Polyjacking)

polyjacking and old mudjacking for Kansas City and St. Louis locationsWhat is mudjacking? Mudjacking is a concrete repair method used to lift and level sunken concrete. Since the 1900s, many businesses and homes have benefitted from mudjacking. It has been used to stabilize basement floors, driveways, sidewalks, patios, garage floors, and more. Mudjacking has been used for decades, so there are no surprises when you use this method. You know exactly what you are getting, for better or for worse.

In some cases, mudjacking can be a temporary solution due to its inability to resist moisture. As a result, the slurry may break down, wash away, and weaken. Because of these drawbacks, polyjacking has gained popularity over the years. If you have sunken concrete, we recommend polyjacking so you can save money and time in Missouri, Kansas, and the surrounding area.

Benefits of Polyjacking vs Mudjacking

Material and Drill Holes

Aside from not being moisture resistant, mudjacking uses a heavy cement-based mixture that weighs nearly 100 lbs per cubic foot. Many large holes are drilled through the slab so the material can pass through the slab, fill in the voids, and lift the slab back in place.

With polyjacking, polyurethane is used to lift and level sunken concrete to its desired height. Polyurethane weighs about 2 lbs, requiring fewer and smaller drill holes for the injection process. Within a few seconds, a chemical reaction occurs and polyurethane turns into foam. The foam expands and fills in voids under the slab.

Curing Process

Mudjacking can take 1-2 days to complete as opposed to polyurethane foam which cures within 15 minutes.

Long Term vs Short Term Repair

Since polyurethane foam is lightweight, it won’t burden loose or weak soil under the slab. This prevents future settling, making it a long-term repair solution. On the other hand, mudjacking is a short-term repair method because it uses thick material that overburdens loose soils.

Patched Holes

Since mudjacking requires many large holes, more patchwork is needed. Mudjacking patched holes are more noticeable and less attractive than polyjacking’s patched holes.

Both mudjacking and polyjacking achieve the same results when lifting and leveling sunken concrete, but polyjacking has become a preferred method over traditional mudjacking.
