A-1 Concrete Leveling's patented technology is similar to what you may know as Mudjacking, but there are some significant differences.
First of all, the A-1 process works at 5 psi, a much lower pressure than traditional mudjacking which can go as high as 700 psi. Using such a low pressure enables the lifting of concrete with less risk of cracking or damage to the surrounding area. It also allows the material to fill the voids under the slab much more fully.
The A-1 Concrete Leveling process also uses smaller holes, only 1 inch in diameter (about the size of a quarter) which is three to eight times smaller than conventional mudjacking. This leaves your concrete driveway, sidewalks, patio or porches much cleaner and closer to their original look. And even though 99% of the jobs we complete never need lifted again, if they do we can reuse the same holes. Most mudjackers will need to drill new holes if the concrete needs pumped again.
Another big difference between traditional mudjacking and A-1 Concrete Leveling is our environmentally friendly, concrete-free AgLime slurry. It is a proven stable material with over 500,000 jobs completed nation wide. Traditional Mudjacking uses a soil-based mud slurry or sand and concrete mixture that doesn't flow as well and can erode and lose support much more quickly requiring a higher rate of return to re-lift the concrete. Our call back rate for resettling is less than 1 percent.
