Dry summers
When clay dries out in summer, it shrinks and opens voids under slabs.

Concrete leveling + foundations
Driveways, patios, pool decks, and foundations. If it is sinking in Lee's Summit, we can help.

Lee's Summit growth
Lee's Summit has grown fast. Alongside the older homes around downtown, newer subdivisions have spread out toward Longview Lake, Lake Jacomo, and Lakewood. Those newer homes often come with long driveways, big patios, pool decks, and wide sidewalks. That is a lot of concrete sitting on Missouri clay.
Why concrete sinks
The result is a driveway that drops at the garage, a patio that tips toward the house, or a sidewalk with a trip hazard.

Lifting slabs without tearing them outPolyjacking
We use ground penetrating radar to find the voids under the slab, then inject high-density polyurethane foam through small 5/8 inch holes. The foam fills the void and lifts the concrete back toward level. It will not shrink, it repels water, and it is light enough that it does not overburden the soil.
Foam cures quickly, so concrete can often be used again soon after the repair.

The bigger picture
Sometimes the sunken patio is a symptom, not the whole story. Water that runs toward the house from settled concrete can end up in the basement. And the same soil movement that drops a driveway can settle a corner of the house.
If you are also noticing cracks in drywall or brick, doors that stick, or water in the basement, we will look at those during the same visit. Depending on what we find, the answer could be foundation repair with steel push piers or helical piers, basement waterproofing, or crawlspace encapsulation.
A garage slab that has dropped can leave a lip at the driveway and let water run inside. It is a common place for polyjacking.
A pool deck that settles can tip water toward the pool or the house. It is a common place for polyjacking.
