Our technicians take many things into consideration when providing an estimate for concrete leveling including the size of the concrete area, condition of the slabs, and how much the concrete has settled. The average job is usually within just a few hundred dollars. Regardless of the job size, concrete leveling is generally less than half the cost of concrete replacement.
Mudjacking has been the industry standard for concrete leveling for many years. It utilizes a clay/mud material pumped beneath the concrete slab to achieve lift. Mudjacking requires a 2″ hole to inject material and, like concrete, can take several hours or even days for the material to fully cure.
Polyurethane injections are quickly replacing the tradition mudjacking as it requires a smaller injection hole of about 0.5″, cures in a matter of minutes, and carries a much lower risk of additional settling later due to its light weight properties. Polyurethane injections use a two-part mixture injected beneath the concrete to create an expanding foam to achieve lift. By the time the technician has finished lifting and cleaning up the work area the material is already cured and safe for regular traffic again. Polyurethane is less likely to experience additional settling later as it is very lightweight and the material does not break down or wash away with moisture.
Most concrete leveling installations take only a small portion of the day. When using polyurethane the material will be cured by the time the installation crew has finished patching the injection holes and cleaning up. In most cases you’ll have a level, fully functional concrete surface within just a couple of hours!
Polyurethane can cure in warm, cool, and even wet conditions. There are very few scenarios that concrete lifting is not recommended. One example of concrete lifting not being recommended is if a slab is cracked into multiple small pieces as it becomes very difficult to lift all of the pieces evenly. Concrete leveling is not recommended when the weather is below-freezing and the ground has frozen.
Within the first few years after concrete has been poured the soil compacts naturally and will not experience such a dramatic compaction again unless the soil is disturbed, flooded, or significant weight is added. Concrete corrected by mudjacking is more likely to experience additional settling than concrete corrected by polyurethane injection because the material used is not only adding up to 150 pounds per cubic foot to the void beneath the concrete, but it can also be washed away and broken down. Polyurethane injections are less likely to experience additional settling as the material weighs in at about 2 pounds per cubic foot and is hydrophobic so it will not break down or wash away due to the weather.
All polyurethane injections are covered by BASEco’s warranty.
The most common reason for concrete to settle is due to moisture. As the soil beneath the concrete gets wet and dries out it compacts the soil or leave voids in the soil that allow the concrete to settle. To avoid settled concrete, it is recommended to correct drainage near the concrete by extending your rain gutters away from the concrete and maintaining a positive grade. Soil can also compact due to the weight of traffic using the concrete surface or it can settle naturally over time.
