Gumbo Clay vs. Your Foundation’s Plumbing
Cibolo’s slab leak story starts under the concrete: Houston Black clay swells dramatically when soaked and shrinks just as hard when dry, flexing foundations through every wet-dry cycle. Builders answered with post-tension slabs, which resist cracking — but the water lines cast into or beneath those slabs still absorb the movement. Over enough cycles, a fitting or a rubbed line gives, even in PEX-era construction that owners assume is leak-proof.
And a slab leak on this soil is self-accelerating: the escaping water keeps the clay beneath your foundation permanently swollen while the surrounding soil cycles normally, creating differential movement that stresses the slab — and the remaining plumbing — even more. That feedback loop is why we treat Cibolo slab leaks as urgent, not someday, repairs.
Finding Leaks Under Post-Tension Concrete
Post-tension slabs raise the stakes on accuracy: those slabs contain steel tendons under enormous tension, and cutting concrete blind risks severing one — an expensive, genuinely dangerous mistake. Our slab leak detection Cibolo process is built for it: acoustic listening to pinpoint the leak, electronic line tracing to map the plumbing, pressure isolation to confirm hot or cold side, and thermal imaging for hot-line leaks warming the floor.
We also locate tendons before any concrete is opened. The result is one small, correctly placed access hole — or better, the determination that a reroute avoids opening the slab entirely. Homeowners usually call us after noticing a jumped water bill, warm tile in Falcon Ridge or Bentwood Ranch floor plans, the meter creeping with everything off, or the water heater cycling nonstop.
Reroute-First Thinking, With Every Option Priced
For many Cibolo slab leaks, the smartest repair never touches the concrete: we abandon the failed under-slab run and reroute new PEX overhead through the attic and walls. In Cibolo’s 2000s floor plans this is often clean and fast — accessible attics, modern framing, manifold systems that make isolation simple — and it eliminates the post-tension cutting question entirely.
Where a direct spot repair makes better sense, we do it with tendons located and marked. Either way you get both options priced, our reasoning in plain English, and foundation leak repair documentation thorough enough for your insurance claim and your own records — including detection findings, photos, and the repair scope. On this clay, that paper trail matters at resale.

Slab Leak Repair in Cibolo — FAQs
Can you cut into a post-tension slab in Cibolo without hitting a tendon?
Yes — but only with the tendons located first, which we do before any concrete is opened. Most Cibolo homes built after 2000 are post-tension, and cutting one blind can sever a stressed tendon. This is exactly why slab work here belongs with a contractor who locates leaks precisely and maps the slab before touching it — and why we often recommend an overhead reroute that avoids cutting altogether.
What does a slab leak do to a foundation on Cibolo’s clay soil?
It creates a permanently wet, permanently swollen zone in soil that’s supposed to cycle evenly. That differential — one patch of gumbo clay swollen while the rest shrinks through a dry spell — moves the foundation unevenly, which can crack finishes, rack doors, and stress other plumbing. It’s the main reason we tell Cibolo homeowners not to sit on slab leak symptoms.
How do I check for a slab leak at my Cibolo home?
Turn off every fixture and water-using appliance, then watch your meter — movement means water is going somewhere. Other tells: an unexplained jump on your City of Cibolo or Green Valley SUD bill, warm spots on floors, faint running-water sound, or a musty smell along baseboards. Any of those, call (210) 555-0199 — electronic detection confirms or rules it out without tearing anything open.
