Tunneling for slab leaks Victoria TX means we dig a controlled access tunnel under your foundation, reach the failed pipe, and repair it in place. No jackhammering your living room. No torn-up tile. If you have a hot spot on the floor, a climbing water bill, or water pooling near a wall, we find the leak and fix it. Serving Victoria County and all of Victoria, TX.
Tunneling for slab leaks Victoria TX is a below-slab access method that reaches a leaking pipe without breaking through the finished floor above it. We excavate a narrow, shored tunnel from outside the foundation or from a garage or utility closet, follow the pipe run to the failure point, and repair or replace the damaged section. Copper pipes, PEX pipes, PVC pipes, and older galvanized pipes all fail under a slab, and tunneling gets us to the exact spot with a concrete saw only touching the slab edge, not your kitchen tile.
Most Victoria homes sit on expansive clay soils that shift with our wet-and-dry cycles, and that movement stresses under-slab lines until a pinhole leak turns into a pipe burst. If your water bill jumped and you hear water running when nothing is on, you likely need tunnel leak repair Victoria Texas. We use acoustic listening devices and thermal imaging cameras to pin the leak before we ever cut concrete, so the tunnel goes to the right place the first time.
Every tunneling job includes detection, the tunnel, the pipe repair, testing, and concrete restoration at the access point. Here is what you get, and where add-on costs can come in if the job turns out bigger than the initial detection suggested.
Electronic leak detection equipment, acoustic listening devices, and thermal imaging cameras pinpoint the leak before we dig. Pressure testing gauges confirm hot or cold side. This is included in every job and usually takes one to two hours on site.
We cut a small access point with a concrete saw, hand-dig the tunnel, and shore it to OSHA specs. Tunnels run three to four feet deep and stay narrow. Shoring, ventilation, and confined-space safety gear are all part of the job, not an extra.
We cut out the failed section and install new pipe with rated couplings. Copper, PEX, PVC, and cast iron each get the right materials and method. If the whole run is bad, we quote replacement before we start so there is no mid-job surprise.
Before we backfill, we pressure-test the repaired line and check the surrounding soil with moisture meters. If it does not hold, we do not close it up. You get a walkthrough and the test results before we finish.
We backfill in compacted lifts and patch the access point with concrete patch mix matched to your slab. The finished surface sits level with the surrounding floor. Full flooring restoration is not included, but most jobs leave the finished floor untouched.
We start with electronic leak detection equipment, acoustic listening devices, and thermal imaging cameras to isolate the leak. Pressure testing gauges confirm whether it is on the hot side or cold side. This usually takes one to two hours and tells us exactly where to tunnel before anyone cuts anything.
We map the pipe run with a pipe locator and video pipe inspection camera, then choose the entry point. That is often outside the foundation wall or through a garage slab. You see the plan and the price before we dig. No surprises on the invoice.
We cut a small access opening with a concrete saw, then hand-dig and shore the tunnel with trenchless tunneling equipment and proper shoring. Tunnels run three to four feet deep and stay narrow. Most excavations take four to eight hours depending on soil and depth.
Once we reach the failure, we cut out the bad section and repair or replace it. Copper gets a new coupling or a full section swap. PEX and PVC get new pipe and fittings. Cast iron and galvanized pipe usually get replaced in that run. We use pipe clamps and couplings rated for the line, then seal joints with pipe sealant.
We pressure-test the repaired line, check for moisture with moisture meters, then backfill in lifts and compact. The access point gets concrete patch mix and is finished level with the surrounding slab. You get a walkthrough, and we do not leave until the line holds pressure.

Pressure testing gauges confirm whether it is on the hot side or cold side. This usually takes one to two hours and tells us exactly where to tunnel before anyone cuts anything.
Pick up the sound of pressurized water escaping a pipe under the slab. This is the fastest way to confirm a pinhole leak or pipe burst location before we cut anything.
Show temperature differences on the floor surface to reveal hot water line leaks and wet spots under tile. Used alongside acoustic gear to narrow the tunnel entry point.
Camera the inside of drain and sewer lines to find cracks, bellies, and root intrusion. We record the pass so you can see the problem and the finished repair.
Traces the pipe run and reads moisture and pressure changes to pinpoint under-slab leaks. It is how we decide whether tunneling is the right approach or a simpler repair will do.
Confirm whether the leak is on the hot or cold side and verify the repair holds before we backfill. No line gets closed up without a passing pressure test.
Cut clean access openings at the slab edge and break out concrete when a garage or unfinished slab is the better access route. Dust control is set up before the first cut.
A homeowner noticed a spike in the water bill and a faint sound of running water at night. The leak was under finished hardwood in the living room, and two other plumbers had quoted a full slab break-out with flooring removal.
After: We tunneled in from the exterior foundation wall, replaced the pitted copper section with new copper and couplings, and pressure-tested the line. The hardwood stayed in place. The water bill dropped back to normal on the next cycle.

A 1960s home had a sewer backup that returned after every snaking. The camera showed a cracked cast iron section under the slab with root intrusion at the joint. The homeowner was ready to break out the whole bathroom floor.
After: We tunneled from the side yard, replaced the failed cast iron stretch with new PVC set to proper slope, and cameraed the finished line before backfilling. The backup stopped, and the bathroom floor was never touched.

A hot spot appeared in the bathroom tile and the tenant could not move out during repairs. The leak was on a hot water line under the slab, and the property owner needed it fixed without tearing up the bathroom.
After: We tunneled from the adjacent utility closet, repaired the hot water line, and restored the access point with concrete patch mix. The repair finished in two days, the tile stayed intact, and the unit never went vacant.
Book this service →Most under-slab leaks announce themselves the same way: a climbing water bill, a hot spot on the floor, or water where it should not be. Here is what we fix and why waiting makes it worse.
Ask a pro →We locate the leak with acoustic and thermal gear, confirm it with pressure testing, and repair the pipe through a tunnel. Most billing surprises trace back to a single failed section we can fix in one to three days.
We trace the hot water run, tunnel to the failure, and repair or replace the section. We also check the rest of the run for the same corrosion pattern so you are not back in six months for the next pinhole.
We find the source, repair the under-slab line, and dry-test the area with moisture meters before we close up. If the water is coming from a water heater or supply fitting instead, we fix that and save you the tunnel cost.
We camera the line with a RIDGID SeeSnake, locate the break, and repair or replace the failed section through a tunnel or outside excavation. You get a camera recording of the finished line before we backfill.
We locate the leak with acoustic and thermal gear, then dig a shored access tunnel from outside the foundation or through a garage slab to reach the pipe. We repair or replace the failed section, pressure-test the line, then backfill and patch the access point. Most jobs take one to three days from detection to finished repair.
Tunnel leak repair is fixing a leaking under-slab pipe by digging a narrow tunnel beneath the foundation instead of breaking out the finished floor above it. Your tile, hardwood, or laminate stays put. We reach the pipe, cut out the bad section, install new pipe and couplings, and test the line before closing the tunnel.
Typical 2026 pricing in this area runs $3,500 to $9,500 depending on tunnel depth, pipe material, and how much pipe needs replacing. A single spot repair on a shallow line sits at the low end. Long runs of cast iron or galvanized pipe needing replacement push toward the high end. Detection and the estimate are free.
For most occupied homes, yes. Tunneling avoids tearing out flooring, cuts dust and noise, and usually finishes faster because there is no large concrete pour to cure. Breaking concrete makes sense for a shallow leak in a garage or unfinished area where flooring is not a concern. We tell you which fits your situation.
Water under your slab does not fix itself, and every day it runs costs you on the meter and stresses your foundation. Call us and we will locate the leak, quote the repair, and get you on the schedule. Licensed, insured, and available 24/7 for emergencies.
