Concrete Raising (Mudjacking)
Are mudjacking and slabjacking the same thing?
Yes, mudjacking is just another name for slabjacking, which refers to raising of concrete slabs.
Why is mudjacking superior to other forms of concrete raising?
Mudjacking provides the greatest control over the lift. The moment we release the pump trigger, the slab stabilizes in that position. With other techniques the slab continues to rise after the injection stops or the slab can compress the fill after it is blown in. Also mudjacking does not pump chemicals into the soil. It does not damage the surrounding landscape and it costs less than the new gimmicks out there. Trust the process that’s tried and true and not some new technique that blows sand or pumps chemicals.
How do you charge for mudjacking?
Estimates are based on time and materials — how long will it take our crew to complete the work and how much slurry is required. Prices are based on the assumption that there are no voids. If a significant void is discovered, we may ask you to approve a small surcharge before we proceed.
How long does mudjacking take?
Most projects are completed in just hours and are ready for use as soon as we leave.
How visible will the filled holes be?
We use 1-in. diameter holes, the smallest holes in the slabjacking industry, and we fill the holes with tinted mortar for the best possible color match. Pressure washing will make the surrounding surface look clean and improve the match.
How much can I save by raising rather than replacing concrete?
Mudjacking typically costs about one-third as much replacing concrete because there is no demolition or landscaping restoration or minimum truck load fees and it requires less labor, equipment and hauling.
What causes concrete to sink?
Concrete settles from poor compaction, improper soil preparation, erosion, excessive loading or poor grading. Downspouts should direct water away from the foundation and paving and landscaping should slope down and away from foundations to avoid water problems.
Will a raised concrete slab continue to settle? Is mudjacking permanent?
We have mudjacked thousands of concrete slabs each year since 1992 and we very rarely have callbacks. We warranty our work for up to three years.
What can I do to preserve my concrete and prevent further settling, deterioration or cracking?
Horizontal concrete surfaces should be cleaned and sealed every two years to protect them from moisture and salt. Landscape surrounding areas to direct water away from the structure. Try to keep heavy dumpsters and delivery trucks off your concrete driveway during remodeling projects. Avoid using salt on your concrete. And keep cracks sealed with self-leveling concrete-colored caulk.
What happens if my concrete cracks during the project or if it cracks the following year?
It’s highly unlikely. We only crack 2 or 3 slabs a year. These cracks typically are very small and happen on slabs that are weak or narrow. If we feel a slab may crack, we will stop and discuss the options. If the slab was poured with a substandard strength concrete and no reinforcing rod, it will be more susceptible to cracking. With Minnesota’s extreme temperatures, frost heave is common. Frost heave is the leading cause of cracks in concrete slabs. Creating positive water drainage and sealing joints to prevent water intrusion will minimize or eliminate frost heave.
What happens if you can’t raise my slab to achieve positive drainage and alignment of sections?
If for some reason we cannot achieve positive drainage and alignment, we will discuss replacement options.
Can mudjacking be used to raise a section of asphalt paving that has sunken?
No. Asphalt pavement is not firm enough to lift.
How long is your raised concrete warranty and what does the warranty cover?
Our work is warranted for up to three years. The warranty covers any settlement of slabs that we raised. We will re-raise the slab at no cost to the owner if needed.
Are you insured?
We carry $3 million liability insurance, $500,000 workers compensation insurance and $5 million umbrella coverage.
What do you do to make your concrete last?
We used high-strength, 4,000 psi minimum mix and install reinforcing rods in every slab. We cut control joints strategically to prevent random cracking, and we seal every job with a penetrating sealant to extend curing time and prevent salt intrusion.

How much snow needs to fall for you to plow?
Typical plowing contracts start at 1.5-in., although some of our commercial clients are set at a 1-in. trigger depth.
How do the amount of snowfall and number of storms impact what I pay?
Most of our snow removal contracts are billed by the hour or the inch. These clients spend less in mild winters and more in severe winters. If you are a contract client you pay one fee for the entire season no matter how much snow falls.
