Our Services:Slab Void Fill & Stabilization
Empty spaces under your slab leave it unsupported, so it can crack and sink. We find the voids and fill them to support the slab again.
We find the void before we fill it.
We locate voids with readings and test holes, so you pay to fill what is actually there.
Signs of voids under your slab
- ★A hollow sound when you tap the floor
- ★Cracks in tile or concrete in one area
- ★A sunken spot in the floor
What causes slab voids in Spring, TX
Flooding
Homes along Spring Creek and Cypress Creek that flooded during Harvey are the most common void fill jobs in Spring.
Slab leaks
Leaking pipes wash soil out from under the slab.
Drought
Clay shrinks away from the slab in long dry spells, leaving gaps.
Poor compaction
Fill that was not packed well at construction settles and leaves space.
Erosion at the edge
Water running along the slab edge carries soil away.
Animals
Burrowing animals can dig under the slab edge.
How we fill voids
- STEP 01Locate
Voids are found by sounding, elevation readings and test holes.
- STEP 02Drill
Small injection holes are drilled through the slab.
- STEP 03Inject
Grout or foam is pumped in until the void is full.
- STEP 04Patch
Holes are patched to match the floor.
- STEP 05Fix the cause
Leaks or drainage are addressed so the void does not return.
Void fill costs
Cost depends on how large the voids are and whether grout or foam is used.
FAQs
Grout or foam?
Cement grout suits large voids and costs less. Foam is lighter and sets fast. The size and location of the void decide.
Will void fill lift my slab?
It is meant to fill and support, not lift. Some sections may rise slightly as the void fills.
How long does it take?
Most void fill jobs are done in a day.
Will the void come back?
Not if the cause is fixed. That is why we check for leaks and drainage problems too.
