💧 What Is a Slab Leak?

A slab leak is a water leak that occurs beneath the concrete foundation (or "slab") of a building. Most homes in Texas are built on slab foundations with water lines running underneath. Over time, these pipes may corrode, crack, or burst, leading to hidden leaks that can undermine your home’s structure.

🔧 Slab Leak Repair Options

  • Every home and leak is different, which is why we offer multiple repair strategies:

  • ✅ Pipe Rerouting

  • When possible, we bypass the damaged underground pipe by installing new water lines through walls, ceilings, or attics. This is faster, less invasive, and often more cost-effective than breaking the slab.

  • ✅ Spot Repair Through the Slab

  • If the leak is isolated and accessible, we’ll carefully remove a small section of concrete, repair the pipe, and then restore the flooring and slab to its original condition.

  • ✅ Tunneling Under the Foundation

  • For more extensive or centrally located leaks, we may tunnel underneath the slab to access and repair the damaged pipe. This avoids cutting into interior flooring and is a preferred option in finished homes.

  • ✅ Pipe Lining / Epoxy Restoration

  • If your existing pipes are mostly intact, we can insert an epoxy lining into the old pipe to seal the leak from the inside — no digging or rerouting required.

  • We’ll help you choose the right option based on the location, pipe material, damage severity, and your budget.
