Interior Piers and Tunneling in Wichita Falls, TX: Reaching the Low Point Under the Middle of the House
Interior load points get reached two ways, through your floor or from a hand-dug tunnel, and we price both on the same written quote.
- Free on-site inspection
- Both access routes priced
- Written itemized quote
Wichita Falls Foundation Works reaches interior load points under Wichita Falls slabs two ways, through the floor or from a hand-dug tunnel, and prices both on the same written quote. Which one suits your house is a decision about money against disruption, and we make it with you at the free on-site inspection, long before our crew shows up.
Call (940) 202-0406 and we'll get that inspection on the calendar. Nobody should find out about a hole in the living room floor after signing.
What interior pier and tunneling work includes
Two access routes exist and we price them separately. Through the slab, we locate a beam by drilling test holes before a core or a cut opens the floor. From a hand-dug tunnel, we open a shaft at the perimeter and shore the passage as it advances, and your floor stays untouched.
This work sits inside slab foundation repair wherever the low point sits under the middle of the house, away from any outside wall. Who bills what matters. Piers set inside a tunnel go on their own line, a plumbing repair found in the tunnel is the plumber's bill, and flooring after a through-slab pier is a separate trade entirely.
What you get in writing before the floor is opened
Four commitments come in writing before either route is chosen. You get a free on-site inspection first, then a written itemized quote broken into separate lines.
We set a scheduling window up front, and the warranty terms are written down too, transfer language spelled out. That means you read what passes to the next owner, what a transfer costs and what voids it. Either way, Wichita Falls and Wichita County get the same paperwork.
Signs the low point is inside, not at an outside wall
A dip you can feel walking the hallway, with every door on the outside walls still closing fine, usually points at an interior load-bearing point that has dropped.
- A dip or slope you can feel walking the hallway or the kitchen.
- Cracked floor tile and opened grout lines running right across a room.
- Interior doors binding when the ones on outside walls still close.
- Sheetrock cracks at the corners of interior door frames.
- A warm spot, a damp patch or an unexplained water bill.
- Furniture that rocks in the middle of a room on a slab floor.
Our elevation readings settle where the low point actually is, and the crack pattern alone never will.
What Wichita Falls homeowners get from Wichita Falls Foundation Works
The through-slab against tunnel decision comes down to money against disruption. What a tunnel saves you in floor covering, it costs in dollars per foot. Interior piers are the minority of slab jobs around Dallas-Fort Worth, going by what one North Texas repair company publishes, so a quote that puts most of the piers inside deserves an explanation before you sign it.
Ask any bidder who carries the plumbing bill if a lift breaks an under-slab line, and get that answer in writing alongside proof of general liability insurance and the warranty transfer terms. We put a plumber's leak test in the scope wherever jacking is, and we do it before the floor is open.
The City of Wichita Falls licenses and registers contractors and requires a permit before repair or alteration work starts; ask to see both.
Through the slab compared with tunneling underneath
Through the slab. This is the cheaper route at $125 to $175 per pier on top of the pile price, and it costs you the floor covering.
Tunneling. Our crew never comes inside except to read elevations, your flooring stays put, and it runs $165 to $500 per linear foot.
What happens to a tunnel afterward is a real disagreement in the trade. Some crews backfill it in compacted lifts, and at least one Dallas company leaves tunnels open on purpose so a future plumbing repair stays reachable. Either way, we send a suspected leak for a hydrostatic plumbing test before we price piers.
How the job runs, elevation survey to patched floor
- Free on-site inspection and elevation survey, our estimator taking interior readings to map where the low point actually sits.
- The decision: through-slab or tunnel, priced both ways, and we state the flooring consequence plainly.
- Preparation inside: furniture out or off the walls, floor covering pulled back, jackhammer and saw work scheduled with you because it is loud.
- Access: an 8-inch core or a cut opened next to the beam, or a 4-foot shaft and a hand-dug tunnel shored as it goes.
- Piers set: a bearing plate laid at the bottom, pier sections driven from a stand inside the opening.
- Lift and void fill: the section brought up while our crew reads elevations, then the void under the slab filled.
- Patch: the hole finished flush with structural concrete, left to cure before flooring goes back down.
Which Wichita Falls houses end up with piers inside
The Census Bureau's 2020-2024 housing tables say the age of a Wichita Falls house runs roughly by ZIP: 76301 at a median of 1956 and 76309 at 1959 hold the oldest stock, 76306 is the 1960s ZIP, and 76308, the largest ZIP by unit count, sits at a median of 1976 with most of its houses built in 1970 or later.
In USDA soil survey data for Wichita County, Kamay is the soil most often mapped under the developed city, and its clay subsoil carries a plasticity index of 29, high on the NRCS shrink-swell scale. The City of Wichita Falls requires a permit to repair or alter a structure, and its published exemption list does not name foundation work.
How much do interior piers and tunneling cost in Wichita Falls?
An interior pier through the slab adds $125 to $175 on top of the exterior per-pier price. Tunneling runs $165 to $500 per linear foot, and how far the tunnel runs sets which end of that band you land on (see the price table for a short run against a long one).
Flooring that does not go back down, jackhammer access, tunnel depth and whether it needs shoring all move the numbers. Call (940) 202-0406 and we'll price both routes for your house at the inspection.
| Work | Typical range | Notes |
|---|---|---|
| Interior pier set through the slab (added to the exterior pier price) | $125 to $175 per interior pier | The surcharge for breaking and patching the slab, not the pier itself. Flooring, furniture moves and finish repair are on top. |
| Under-slab tunneling | $165 to $500 per linear foot of tunnel | A 3 ft by 3 ft cross section. A short 8 to 15 ft tunnel to one bathroom runs about $3,000 to $7,000; a long run under the middle of a house can pass $20,000. Piers set inside are billed on top. |
| Concrete pressed pilings (pressed concrete cylinder piles) | $300 to $700 per pile installed | The per-pile price the interior surcharge is added to, where pressed cylinders are the pile. |
| Steel push piers (pressed steel piles) | $500 to $1,500 per pier installed | The per-pier price the interior surcharge is added to, where steel is the pier. |

Interior pier and tunneling questions from Wichita Falls homeowners
When does a pile have to go under the middle of the house instead of the perimeter?
When the elevation readings put the low point inside the house, which usually means an interior load-bearing point has dropped. No pit at the grade beam reaches that point. The readings settle it, and we'll tell you what they say before anyone quotes a pier.
Is it better to break the floor open or to tunnel in from outside?
Tunneling keeps our crew out of the house and leaves your flooring alone, at $165 to $500 per linear foot. Going through the slab is cheaper, a $125 to $175 surcharge per pier, and it costs you the floor covering. We write both numbers down at the inspection.
What does an interior pier add to the price of the job?
$125 to $175 per interior pier, on top of the per-pier price. That surcharge pays for breaking and patching the slab, and the pier itself is priced on its own line. See the per-pile price it is added to.
What does tunneling cost, and how long is a typical tunnel?
$165 to $500 per linear foot for a three-foot by three-foot tunnel. A short run to one bathroom lands far below a long run under the middle of the house, and the price table carries both. Piers we set inside are billed on top.
Does the tile or wood floor go back down afterwards?
Flooring that comes up over an interior pier generally does not go back. We patch the slab hole and finish it flush, but the floor covering and the finish repair are a separate trade and a separate bill. That is the main reason to choose a tunnel.
Which rooms do we lose while interior piers go in, and for how long?
The rooms we are working in. Furniture goes out or off the exterior walls, floor covering comes up, and a cut hole in the slab holds a pipe stack and a drive stand. Concrete dust settles on everything. Going by the timelines North Texas repair companies publish, an interior job typically runs four to five business days, where exterior work runs one or two.
Can a tunnel be used to fix a plumbing leak at the same time?
Yes, and that is one reason to tunnel. It reaches an under-slab drain line without opening the floor. The plumbing repair inside the tunnel is the plumber's separate bill, and our foundation quote does not carry it. Get the leak answered with a hydrostatic plumbing test before we price piers.
These are two different trades, and the choice is dollars per foot against a floor you will not get back. Both belong on paper before anyone opens anything. Call (940) 202-0406 and we'll price your house both ways at the inspection, then let you pick.
