Drainage and Root Barriers
Mature trees close to a slab can pull serious moisture out of the clay in a dry summer.
Drainage and Root BarriersWells Branch was built out from the early 1980s under its own municipal utility district, so most of the housing is now around forty years old with trees to match. Big trees on clay soil are a very common combination here.

Mature trees close to a slab can pull serious moisture out of the clay in a dry summer.
Drainage and Root Barriers
Slabs from the 1980s have been through every drought since, and some have stopped coming back.
Slab Foundation Repair
Where one side has settled for good, lifting is done in measured stages from elevation readings.
Foundation LevelingForty years of shrink and swell is long enough for a house to develop a settled shape rather than a seasonal one. That is the main thing distinguishing this housing from newer subdivisions further north: the movement has had time to become permanent, and the trees planted with the houses are now big enough to matter.
When you call, tell the provider how close the nearest large tree is to the slab, which side the yard drains toward, and whether any past foundation work was done. A surprising number of homes in older neighborhoods have had piers installed at some point, and the paperwork, if you still have it, saves a lot of time.
Live oaks and cedar elms planted in the 1980s now draw heavily from the soil beside the house through a dry summer.
Grading that worked when the lot was new can be buried under forty years of added beds, edging and raised soil.
Older houses may already carry piers or patched cracks. Knowing what was done before changes how the readings are interpreted.
The useful first step is almost always measuring, because in housing of this age the difference between "always been a bit uneven" and "dropping now" is not something you can see. Once there is a plot, the options are clear: moisture control if it is seasonal, piers if it is not.
Where a big tree is the driver, a root barrier and a watering routine may do more than anything else, and both are covered on the drainage and root barriers page. If piers are warranted, the pier comparison explains the choice, and leveling covers the lift.
Housing of a similar era sits just north in Brushy Creek, and the same clay continues northeast under Pflugerville. Ask for an inspection or read the warning signs guide first.
Pier count, depth and access set the price, and it is usually quoted after the elevation readings rather than over the phone. Mature landscaping and fences can make access harder, which affects the figure. Ask the independent provider to put the pier positions and the scope in writing before any work is approved.
Round Rock Foundation Repairs connects callers in Wells Branch and the neighborhoods either side of the I-35 corridor with independent providers. Mention the address and the age of the house. What a visit includes is set out on the inspection page.
Inspection timing is set by the independent provider and depends on their schedule and the property location. Call to check whether a provider is available. Mention any closing date or option period so the provider can say whether it can be met.
Be careful. Cutting large structural roots on one side can destabilize a mature tree, and digging beside a loaded slab can remove soil that is helping to support it. A properly placed root barrier is a planned job, not a weekend with a spade. Ask about it at the drainage visit.
Usually the barrier, if the tree is healthy and worth keeping. Removing a big tree that has been drawing moisture for decades can let that soil rehydrate and swell, which is its own kind of movement. A barrier is a gentler change. Either way it is a decision to make with measurements in hand.
Not automatically, but it has had more opportunities. Each severe drought is another chance for a slab corner to drop and not come back, and this housing has seen several. Plenty of 1980s houses here read perfectly acceptably. Measuring is how you find out which one you have.
