Affordable Concrete raising with Mudjacking
When it comes to the structural integrity and aesthetics of your property, few things are as crucial as the stability of your concrete surfaces. Whether it’s a driveway, sidewalk, or patio, uneven concrete not only detracts from the curb appeal but also poses safety risks. In the realm of concrete repair solutions, mudjacking emerges as a reliable and cost-effective method for restoring and leveling sunken concrete. By injecting a specially formulated mixture beneath the settled slabs, mudjacking offers a swift and long-lasting solution that addresses the underlying causes of concrete settlement, ensuring a durable and even surface for years to come.

The mudjacking / slabjacking concrete raising process
Drill Holes
The first step we take when starting your concrete raising project is to strategically drill one inch holes into the section that requires lifting. These allow us to hydraulically fill the spaces underneath your concrete.
Lift Concrete
A sand-based slurry, infused with Portland cement, is hydraulically pumped through the 1″ holes to fill voids and raise the settled concrete. As the slurry fills the voids and crevices under the concrete slab, the pressure of the filling begins to raise the concrete. We measure the level at which the concrete slab is raised, ensuring it’s raised enough to make it level with the surrounding slabs.
Fill Holes
After our mudjacking crew has completed raising your concrete, we insert a plug into each hole, and patch it with new cement. The concrete slab is ready for use immediately. It is recommended, however, to allow the patch material to set-up before use, which typically takes a couple of hours.
Benefits of mudjacking concrete raising
1
Mudjacking is the most economical means of raising and repairing your concrete.
2
More cost effective than polyurethane concrete raising, and exponentially more cost effective than concrete replacement.
3
When you level your uneven concrete using poly foam concrete raising techniques, ⅝” injection holes (Size of a dime!) are strategically drilled around the areas where the concrete is sunken and requires lifting.

Investment
Why would anyone spend 4 to 5 times the amount of money to have their concrete raised using polyurethane opposed to traditional mudjacking?
It pays to use the more expensive polyurethane method when raising slabs that are poured over very unstable or unsuitable fill. Polyurethane weighs 2-4 pounds per cubic foot compared to 100-150 pounds per cubic foot of traditional mud, making polyurethane material much less likely to overburden unstable soil. In an article written by G. L. Bowen PE. LLC, Helical Piers & Polyurethane Foaming in the April addition of Helical Pier World, Mr. Bowen discussed the advantages of using closed cell polyurethane to fill voids and support floors over peat moss soils in Alaska. In situations like this, light weight polyurethane has a tremendous advantage over much heavier mudjacking materials.
Strength and Support
Is polyurethane strong enough to raise and support concrete slabs?
Traditional mudjacking does have an advantage over polyurethane when it comes to compressive strengths. A contractor can make the compressive strength of mudjacking material be whatever is desired by adding cement or combining cement with lime or sand achieving compressive strengths of 2,400 PSI. Polyurethane’s compressive strength is consistently around 80 to 100 PSI. It is preferable to pump a higher compressive strength material than the existing sub-base.
The End Result
Does the finished job look better than traditional mudjacking?
A feature of polyurethane that will make the end results more attractive, especially to the residential market, is a smaller injection hole. Polyurethane utilizes a hole that is only 5/8” or smaller, compared to mudjacking holes that run between 1” and 2”.
USAGE AND SOLUTIONS
Who wants their concrete raised using polyurethane foam?
US Departments of Transportation seem to be preferring the use of polyurethane concrete lifting for sagging bridge approaches or removing dips in highways. The main reason being the light weight characteristic of the material which will not overburden the soil.
Our experience tells us that conventional mudjacking will be around for a long time. The average consumer will always look for the most inexpensive way to fix settled concrete. However, polyurethane concrete lifting has found a home and will be the solution to raising slabs when a light weight material is needed.
