Foundation repair in Braun Station, the far west side's oldest subdivisions.

That pairing gives these streets their own diagnostic question. The clay out here moves roughly half as much as the black clay east of town, so most of what we measure in Braun Station traces back to water and to roots rather than to seasonal swelling. More than forty years of added beds, patios and regraded yards decide where the water goes, and the mature canopy decides which side of a house dries out first.

AREAS WE SERVE ON THE FAR WEST SIDE: BRAUN STATION EAST AND WEST, MYSTIC PARK AND TIMBER RIDGE, IN 78250 NEAR LOOP 1604 AND BANDERA ROAD, A SHORT RUN WEST FROM OUR VANCE JACKSON SHOP.

The ground under the far west side

Braun Station sits on mixed ground rather than one uniform clay.

Braun Station occupies the 78250 pocket of San Antonio's far west side near Loop 1604 and Bandera Road, and the ground under it is not one soil. Sampling across the area turns up Patrick, Lewisville and Eckrant on 1 to 8 percent slopes. None of them is the deep, dark, dramatic ground people picture when they hear Texas clay. Linear extensibility across 78250 is 5.7 percent, a little under half the 12 percent measured on the Houston Black and Branyon clays that gave the east and south sides of the county their reputation. The local risk score of 43 out of 100 says the same thing in one number. Real movement is possible, but the soil is not the villain it is a few miles east.

Mixed ground changes the failure mode rather than removing it. Bearing can shift from one point along a slab beam to the next, and where the soil is shallow the water falling on a yard never disappears into a deep profile. It runs toward whatever low spot it finds. That is why poor drainage drives so much of the damage here, and why a hard August pulls down the edges that lost their moisture first instead of settling a house evenly all the way around. The subdivisions farther west sit on the same shallow limestone country, which is why foundation repair in Alamo Ranch and Westover Hills read as this geology with a generation less history on top of it.

Forty years on the same slab

The oldest far west subdivisions ask a different question than the new ones.

Forty plus years is long enough for a slab to show its hand. A Braun Station house has now been through every Central Texas drought since the 1970s, including the severe ones, and most of the settlement it was ever going to do has already happened. That flips the usual question. In a new subdivision we are asking whether a pad will still consolidate. Here we are asking whether the crack that has been in the dining room wall since the kids were small is finished or still opening a fraction every summer. Reading the crack itself gets you partway. The floor elevation survey settles it, and that survey is free whether or not the answer leads to repair.

Age brings one item newer neighborhoods do not have yet, which is original plumbing under an original slab. When a drain or supply line that has been buried since the house was built finally gives up, it washes fines out of the soil around it, and the slab loses support in a spot that has nothing to do with the weather. A leak under the slab is worth ruling out before anyone scopes piers, and on a house this age that is a live possibility rather than a formality.

Construction has changed too. Houses from the 1970s and 1980s were poured before post-tensioned slabs became standard in San Antonio tract building, so when something does move under a Braun Station foundation it usually shows up locally, at one corner or along one short run, rather than as an entire side going down. Local movement is the cheaper kind to correct. Where piers are the right answer we set steel piers or hybrid piers and nothing else, pressed to refusal, and where limestone is close the drives are short.

Trees and rerouted water

On shallow ground the canopy and the downspouts decide more than the weather does.

The canopy over Braun Station is the giveaway that these are the older far west streets. Trees planted with the houses are now full size, and where the soil is shallow a full size tree reaches rock quickly, so it draws from a small reservoir instead of a deep one. In a dry summer it can take the available moisture out of the ground on its side of the house and leave the opposite side untouched. That one sided drying is the classic tree and foundation pattern, and the answer is almost never to take the tree out. Root barriers, a consistent watering routine and better drainage handle most of it.

The other half is four decades of landscaping. Beds get built up, a patio gets poured, a walk gets added, a pool goes in, and each change moves water a little. None of it is a mistake on its own. Added together over forty years they can send roof and yard water straight at a slab the builder originally graded to shed it. Deep clay absorbs some of that. The ground here often does not, which is why correcting grade and downspouts is frequently the entire repair out here. Our drainage correction crew handles that side of the work, and how water moves around a San Antonio foundation is the first thing an inspector maps before anyone talks about piers.
