Underground Leak Detection and Repair in Round Rock, TX

The pipe that runs under your lawn and driveway is out of sight until it is not. A buried leak shows up as a soft patch of grass, a sinkhole-like dip, or a meter that never stops.

Signs a buried line is leaking

Underground leaks announce themselves at the surface. A strip of lawn that stays green and spongy through a dry week is one tell. A low spot that sinks as the soil washes out, or mud weeping up through a driveway crack, points the same way. The clearest tell is the meter. With every fixture off, a dial that keeps creeping means water is escaping between the meter and the house.

In Behrens Ranch and other 2000s neighborhoods, the buried runs are usually plastic and long. A small break can travel a good distance before it surfaces near a flower bed or the edge of a patio.

Driveways and patios are where these turn expensive if ignored. Water washing under a slab erodes the base it sits on, and a small void becomes a cracked or sunken section of concrete. Catching the leak while it is still a wet patch in the grass usually means a small repair, not a poured slab. That is the case for tracing it early.

Locating a leak you cannot see

We do not dig to look. Line tracing puts a signal on the buried pipe so we can follow its exact path and depth from above. Listening equipment then picks up the sound of water escaping under pressure, and we walk the run until the sound peaks over the break. That gives us a marked spot, often within a foot, before a shovel touches the ground.

Near Old Settlers Park, where mature trees and irrigation share the same soil, that precision keeps the dig small. If your yard has a patch that will not dry out, call (512) 737-6168 and we can locate it.

Repair without trenching the whole yard

Once the spot is marked, most buried leaks need only a small excavation to reach and repair the break. When a line has failed in several places or is too old to trust, a trenchless pull replaces the whole run instead. It works through access pits at each end, so the lawn, driveway, and landscaping mostly stay put. We size the work to the line, not to the easiest invoice.

Why Round Rock soil hides underground leaks

The ground here works against you twice. On the west side, porous limestone lets escaping water travel sideways and surface far from the break. On the east side, expansive clay swells over a leak and can seal the surface, so the water moves down and out instead of up. Either way, the wet spot you see is a clue, not the location.

That is exactly why tracing beats digging. We follow the pipe and the sound to the real source rather than chasing the symptom across the yard.

Two checks before we dig

A little homework speeds the whole visit. Shut the house off at the main and watch the meter; if the dial keeps turning, the leak sits on the buried run between the meter and the house. Then walk that path and note any spot that is soft underfoot, sunken, or stubbornly green while the rest of the lawn is dry. Those two observations point us at the right stretch of yard before a shovel comes out.

We also rule out the simple culprits first. An irrigation valve, a hose bib, or a pool fill line can mimic a buried main leak, and clearing those can save a dig entirely. Once they are ruled out and the meter still moves, we trace the supply run, listen for the break, and mark it. You see the spot and the plan before we open the ground. If your meter is moving with everything off, call (512) 737-6168.
