Sunken concrete does not always need to be demolished and replaced. When a slab is still structurally sound, concrete lifting can raise it toward its intended position, restore drainage and remove abrupt trip edges.
How concrete lifting works
MI Concrete Lifting drills carefully placed 1-inch injection holes through the slab. A masonry-based slurry is hydraulically pumped beneath the concrete. The material fills empty spaces and builds controlled pressure that lifts the slab. Once the desired position is reached, the holes are patched.
Surfaces that can often be lifted
Why concrete sinks
Settlement from original construction is common around newer foundations and areas built up with fill. Erosion can develop where open joints allow water into the base. Tree roots may also lift one section while nearby slabs settle, creating a dangerous mismatch.
Lifting or replacement?
Lifting is worth evaluating when the concrete remains reasonably intact. Replacement may be the better choice when a slab is severely crumbled, structurally failed or broken into many unstable pieces. A professional inspection can help you avoid paying to replace usable concrete.
Most residential lifting projects can be completed in a single day. For a free inspection in Southeast or Central Michigan, contact MI Concrete Lifting at 517-294-1815 or visit MIConcreteLifting.com.
