Why Concrete Sinks & Settles
What happens underneath a slab when concrete loses support.
Why Concrete Sinks & Settles
Concrete depends on the soil and base beneath it. Settlement, poor compaction, erosion, washout, drainage and previously disturbed soil can create voids or loss of support. When the slab itself remains suitable, leveling or lifting may be an alternative to removal.
What to Look For
Photograph the entire affected area as well as close views of cracks, edges, joints and elevation changes. Note whether the condition is changing, whether water collects nearby and whether a previous repair has failed.
When to Get It Evaluated
If the damage is spreading, creating a trip point, holding water, showing movement or getting worse after winter, an evaluation can help determine whether targeted repair still makes sense.
