Sinking Foundation Repair Converse, TX.
Converse sits where Blackland Prairie clay drains toward the Cibolo Creek watershed, soil that swells after a storm and shrinks back in the summer drought. We seat galvanized steel piers below that moving layer and lift your slab back toward level, with a free elevation survey to start.
How a Converse repair actually goes
Free elevation survey
We grid the whole slab and map it to ±0.01 in. (1/64 in.), producing an elevation profile that shows which zones dropped, which heaved, and where the neutral plane sits.
Engineer-signed pier plan
From that map we set pier locations, depth targets, and a lift sequence that restores grade without over-jacking the sections next door.
Drive, lift, and lock onto steel
Galvanized piers are pushed hydraulically until the equipment reads refusal in competent strata, then the slab is raised and its load transferred onto the steel.
Re-survey and warranty
We shoot the elevations again, document the corrected profile, and hand you the lifetime transferable warranty before the crew leaves.
What the Cibolo-margin clay does to a slab here
The clays along Converse's stretch of the Cibolo drainage are high-plasticity vertisols, many register a plasticity index above 40, which puts them among the most expansive soils in the country. After a wet spring they pull in water and push up against the underside of the slab; through the August dry spell they shrink away from the footing and drop it. Your foundation rides that difference, season after season.
The number that decides whether a repair lasts is the depth of the active zone, how far down the soil moisture keeps cycling. In these Blackland clays it commonly runs eight to fifteen feet, and deeper where a live oak or pecan has been drawing moisture out of one side of the yard. Anything that stops inside that zone is still sitting in moving ground.
That is the whole case for steel piers driven to refusal: they pass through the active clay entirely and seat in strata where the moisture content barely changes year-round. The pier stops when the soil resistance says it has reached load-bearing ground, not at a length somebody guessed beforehand.
Cracks that close by August aren't healing
A brick crack that opens after the spring rains and seems to shut by late summer is tracking the soil's seasonal bounce, not repairing itself.
By the time a corner stays low through the wet season, the movement has stopped self-correcting, that's the point to get it measured.
Signs worth a closer look in a Converse home
On local slabs these tend to show up first at exterior corners and along the long wall running with the Cibolo drainages:
- Stair-step cracks in the brick veneer, or 45-degree drywall cracks running off door and window corners
- A door that binds in spring and swings free by fall, that's soil, not humidity swelling the wood
- A floor that pitches more than about an inch across twenty feet
- Gaps where the fascia or soffit pulls away from the wall plane
- Sheetrock separating at the ceiling-wall joint, often worst down a long north-south hallway
- A visibly low corner you can feel underfoot before you can see it
Questions Converse homeowners ask us
My house is near the Cibolo, is that why the back corner keeps dropping?
How deep do the piers have to go in this part of Converse?
What will a project like this cost me?
We just bought the place, will the warranty mean anything when we resell?
Do we need to move out while you work?
The piers will hold, but won't the soil just push it around again?
Will my racked doors and windows work again once you lift it?
