When a sewer line fails in Houston, the clock starts immediately. Tunnel Now is the sewer line replacement trenching company Houston homeowners and contractors trust when they need the excavation done right, with no sunken trenches, torn-up floors, or second-guessing. We address the issue, dig it properly, and leave your property stable and solid.
A few years ago, a homeowner in Oak Forest called us in a panic. The yard smelled like a swamp, the toilets were backing up, and a plumber had just informed them that the main sewer line had collapsed 40 feet from their home. The trench had to go.
Every week, we receive calls like this from Houston’s Heights to Pearland, Sugar Land, Spring Branch East, Midtown, and Pasadena Texas. Houston’s clay-rich soil, aging cast iron pipes, and slab-on-grade foundations put sewer lines under constant strain. When one fails, you need an excavating crew that knows how to dig properly, compact correctly, and return your property in better condition than they found it.
Tunnel Now is Houston’s preferred crew for sewer line replacement trenching. We collaborate with plumbers, utility contractors, and homeowners to handle the excavation portion of each job, which most people never consider until something goes wrong underground.
The main sewer line extends from your house to the city connection on the street. When that line fails, whether due to tree root intrusion, pipe joint separation, or years of cast iron pipe corrosion, the repair almost always begins with a trench.
In older Houston neighborhoods such as Meyerland, Montrose, and Bellaire, we frequently find original cast iron pipes that are 50 to 70 years old. These pipes crack, sag, and degrade over time.
Add Houston’s notorious clay soil, which swells in wet weather and shrinks in dry spells, and you have a recipe for main line collapses that occur faster than most homeowners anticipate.
Sewer line bellies, foundation shifting, and slow drainage through the lateral lines are all indications that something is wrong underground.
Our crew will complete the excavation from your foundation to the street.
We dig to the proper depth, protect surrounding landscaping and concrete where possible, and stage everything so that your plumber can enter, repair or replace, and exit quickly.
We know what a sewer line belly looks like when we hit it, and we know how deep we need to dig to fix it properly.
This is where things get specific, and Tunnel Now really stands out in the Houston market. Under-slab tunneling is the most precise, high-value service we provide, and many homeowners are unaware that it exists until they need it.
When a sewer line beneath a concrete slab fails, there are two options: break up the floor or tunnel under the foundation. Now there are tunnels. We dig a horizontal access point from outside the foundation, travel through the soil beneath the slab, and reach the problem pipe without touching your flooring, tile, or interior structure.
This is especially important in neighborhoods like Memorial, Friendswood, and West University, where homes have slab-on-grade construction and finished interior floors. Ripping up a kitchen or bathroom to access a failed sewer pipe can cost thousands of dollars in interior restoration. Tunneling avoids all of this.
We provide under-slab tunneling services to repair crews, pipe replacement projects, and plumbing contractors who require below-slab access without demolition. If your plumber has told you that the line under your slab requires repair, contact us before anyone touches your floor.
Trenchless methods such as pipe bursting and pipe lining have gained popularity in Houston, and for good reason. They are faster, less disruptive to your yard, and don’t damage your driveway or landscape. But most companies don’t tell you that trenchless work still requires access pits.
Those pits need to be dug correctly. The wrong dimensions or depth can make pipe bursting or lining impossible, or force a contractor to abandon a project in the middle. Tunnel Now specializes in excavating the entry and exit access pits that pipe bursting and lining crews require to complete their work efficiently. We’ve worked with trenchless teams all over Houston, from Katy to Clear Lake, and we know exactly what they need before they arrive on site.
If your trenchless contractor needs a reliable excavating crew to properly prepare the site, we’re the ones to call.
Building a new home? Setting up a commercial property in the Greater Houston area? Getting your sewer line tapped into the city main is a job that requires permits, precision, and an excavating contractor who knows how Houston’s utility systems work.
Tunnel Now handles sewer tap installation for new construction projects and for properties being connected to Houston’s municipal system for the first time. We coordinate with the city, handle the excavation to the right depth and angle, and make sure every tap is clean and code-compliant from day one.
We work regularly with builders, utility contractors, and commercial developers across the Houston metro. Whether you’re tying into a city main in Spring Branch or connecting a new structure in Pearland, we know the local requirements and we do this work every week.
What follows the trenching and digging is what distinguishes a good excavating contractor from a bad one. Any crew can dig a trench. Not every crew is familiar with proper backfill and compacting techniques.
Poor compaction following trenching in Houston’s clay-heavy soil causes settlement, which means your driveway, parking lot, or yard sinks weeks or months after the job is completed. This process is a headache for homeowners and a major issue for commercial clients who cannot afford a sinking trench in a parking lot or loading zone.
Tunnel Now uses proper backfill materials and compaction equipment for all digging and trenching jobs. We test compaction to ensure it meets industry standards, and we do not leave a job site until the ground is stable.
For commercial clients in Pasadena, the Galleria corridor, and the Energy Corridor, the level of attention to detail is just as important as the dig itself.
Sewer line work does not occur in isolation. Tunnel Now also provides excavation for broader drainage services such as French drains, drainage corrections, and yard grading that directs water away from your foundation rather than toward it.
Houston’s flat topography and heavy rainfall seasons result in ongoing drainage issues. Yard pooling after a storm, soggy ground near the foundation, and slow drainage through your lateral lines are all indications that the grade and soil surrounding your property require attention. We dig the channels, install the drainage systems, and backfill properly to ensure that your yard sheds water as it should.
As a licensed utility contractor serving the Houston metro area, we also perform excavation for water line work, gas line access, and other below-grade utility projects that necessitate careful, experienced digging with soil compaction standards to back it up.
When something goes wrong underground, such as a collapsed main line in Meyerland, a failed under-slab pipe in Memorial, or a new construction tap that must connect to the city main at an exact angle, the quality of the excavation work determines whether everything else is easier or more difficult.
Tunnel Now has been doing this work in Houston for long enough to be familiar with the soil, neighborhoods, permit requirements, and issues that arise in each area of the city. From The Woodlands to Friendswood, from Katy to Baytown, we’ve dug, tunneled, tapped, and compacted it all back.
People frequently ask us, “Who’s the best sewer line replacement trenching crew near me?” The answer is a crew that knows Houston’s terrain as well as its equipment.
