Why concrete slabs sink
Concrete can settle when soil below it changes, fill was not compacted evenly, water moves material away, or voids develop beneath the slab. Houston's long hot periods and heavy rain events can also make drainage and moisture management important parts of the conversation.
How slab lifting works
A provider identifies the low areas and selects injection points. Material is placed beneath the slab to fill voids and create lift. The process is gradual because the slab, adjoining concrete, steps, garage floors, pool coping, and other fixed elevations all limit how far a panel can safely move.
Concrete raising around homes
Common residential projects include driveway panels, front walks, sidewalks, steps, patios, pool decks, and slabs near garages. The goal is not only appearance; elevation changes can affect trip hazards and drainage too.
Questions to ask before hiring
Ask what material will be used, what elevation is realistic, whether void filling is included, how cracks and joints are handled, what drainage issues were noticed, and what warranty applies to re-settlement.
