Round Rock's expansive clay soil is the reason slab leaks are so common here. Understand the geology, the warning signs, and why early detection saves thousands.
Round Rock sits on expansive clay soils that swell when wet and shrink during drought. That endless expansion-and-contraction cycle places severe stress on the supply and drain lines embedded in your concrete slab — which is why Central Texas homeowners experience slab leaks far more often than most of the country.
Why it happens
As the slab flexes with the soil, the rigid copper or PEX lines inside it are pulled, pinched, and eventually fatigue. A pinhole or fracture opens — often on the hot water line first — and water silently erodes the foundation from below.
The warning signs
Watch for: a sudden water bill spike, warm spots on the floor, the sound of running water when nothing is on, soft or discolored flooring, new cracks in walls, and low pressure across the house.
Why early detection matters
A slab leak that costs $1,500 to detect and repair today can become a $15,000 foundation repair next year. Electronic acoustic detection, pressure testing, and thermal imaging let us pinpoint the leak to within inches — without tearing up your whole floor.
Your repair options
Depending on the situation we may recommend spot repair, pipe rerouting above the slab, epoxy lining, or a full repipe. We give you an honest cost comparison so you choose with confidence.
