New water service lines, well-to-house lines, utility trenching and underground hookups — dug at the right depth, bedded and backfilled properly, and cleaned up when we're done. MB General Contracting installs and repairs underground water and utility runs for homes, shops and new construction across St. James, Rolla and Phelps County.
Underground utility work is one of those jobs that is invisible when it's done right and a constant headache when it isn't. A water service line that's set too shallow will freeze and split in a hard Ozark winter. A trench backfilled with the wrong material or without compaction will settle, sag and leave a soft channel across your yard that swallows gravel and cracks driveways. A conduit run without proper bedding can get crushed or nicked. None of that shows up the day the machine leaves — it shows up months or years later, and by then it means digging the whole thing up again.
MB General Contracting is an owner-operated, licensed general contractor based in St. James, and this is the kind of dirty, precise work we do every week. Matthew Buhlinger runs the machines himself, so the person who bids your job is the person on site making sure the line goes in at the correct depth with the right bedding and a properly compacted backfill. We own our own excavators, dozers and skid steers, so we're not renting equipment or waiting on a sub — we show up, dig it right, and put the ground back the way it should be. Whether you're a homeowner replacing a failing line, a landowner running water to a new well or shop, or a builder getting a new house ready to hook up, we handle the underground work cleanly and correctly the first time.
From a single water service line to a full set of utilities for a new build, here's the underground work we take on for property owners across Phelps County and the surrounding towns:
Lines set too shallow freeze; trenches backfilled with rock or without compaction settle and sag. We install below the frost line with proper bedding under the line and compacted backfill over it, so your water stays protected in winter and your ground doesn't cave in over the run.
When a line has to cross a finished driveway, a county road, a paved parking area or established landscaping, we don't have to tear it up. We can push the line underneath with directional drilling (boring) and leave the surface intact.
The Ozark plateau under St. James, Rolla and the towns around them is not easy digging. Much of Phelps County sits on shallow soil over chert and limestone, and it's common to hit rock a foot or two down — especially on the hilly, wooded lots around Rolla and the acreage south toward Salem. Rock changes everything about a utility job: how deep we can trench, whether we need to rip or hammer through it, and how we bed the line once we're past it. We plan for it, and our equipment is set up to deal with it, so a rock ledge doesn't leave your line sitting too shallow.
Rural property here also means a lot of long distances and private systems. Around St. James, homes tie into a small-town Public Water Supply district; but out on the acreage and small farms surrounding it, and down toward St. Robert and the Fort Wood area, plenty of properties run off private wells with the house set well back from the road. That's a long line to trench, at the right depth the whole way, sometimes across a driveway or through a wooded slope. Winter matters too — a proper frost depth here isn't optional, because a shallow line will freeze solid and split. We've been running lines through this ground for 15-plus years, and we install every one to handle the local rock, distance and cold.
Buried lines fail quietly. Here are the things that usually mean it's time to call:
Sometimes a single break in an otherwise sound line is a straightforward repair. But an old galvanized line, an undersized poly line, or one that's been set too shallow is usually money better spent on a full replacement — because patching one weak spot on a failing line just means digging it up again next year. When we're on site we'll tell you which situation you're in and why.
Straightforward, no surprises. Here's how a typical waterline or utility job goes.
Tell us what you need — a new well line, a leak, utilities for a build. We talk through access, distance and what's on the property.
We come out in person, walk the route, check for rock and obstacles, note any driveway or road crossings, and give you a clear plan.
We trench at the correct depth with proper bedding — or bore under any finished surface — and set the line to spec.
Trench backfilled in lifts, compacted, graded back and cleaned up so your ground is left settled and tidy.
Every underground job is priced on what it actually takes to do it right — which is why we come out and look before we quote. The biggest factors are:
We keep it plain: a free, in-person estimate is the only honest way to price buried work, and that's exactly what we give you — no obligation.
Underground work is unforgiving — you can't see the mistake until it costs you. That's why it pays to have the right person and the right equipment doing it:
Matthew Buhlinger runs the machines himself. The person who bids your line is the person setting its depth and compacting the backfill — not a rotating crew.
We own our excavators, dozers and skid steers. No rental delays, no waiting on a sub — and machines set up to get through Ozark rock.
We can open a trench or push a line under a driveway or road with directional drilling. Same contractor, whichever the job needs.

Waterline and utility work also ties into the rest of our site work. If a run needs a trench opened as part of a bigger dig, that's excavating; if standing water or a wet trench is part of the problem, we handle drainage; and once the line's in, we can regrade and restore a driveway or lane that had to be crossed — all with one crew.
Yes — that's one of the most common jobs we do out here. We trench the line from the well to the home, shop or barn at proper frost depth with correct bedding, and if the route has to cross a finished driveway or road we can bore under it instead of tearing it up. Distance and rock are the main things that affect the work, which is why we come out and look first.
It depends on the line. A single break in an otherwise sound line can be a straightforward repair. But an old galvanized line, an undersized poly line, or one that was set too shallow is usually better replaced, because patching one weak spot on a failing line just means digging it up again. When we're on site we'll tell you honestly which situation you're in.
Deep enough to sit below the frost line so it doesn't freeze in an Ozark winter — a shallow line will split the first hard cold snap. The exact depth depends on the type of line and local requirements, but the principle is the same on every job: we set it deep enough to be protected, with proper bedding and compacted backfill over the top.
We do. For new construction we open and coordinate the trenches for water, sewer and underground electric so your new home or shop is ready to hook up. We're a licensed general contractor and also pour concrete in-house, so utility trenching often ties right into the rest of the site work we're already doing on the build.
Yes. When a water, electric or conduit run has to cross a finished driveway, a paved road, a parking area or established landscaping, we can push it underneath with directional drilling and leave the surface intact — no ripping up your concrete or blacktop.
Before we open ground we account for what's already buried on the property and check the likely route so we're not surprised by existing lines. For public utilities, a proper locate should always be called in before digging, and we work with that. When it's a leak on your own line, we trace it to the failure point rather than guessing, so we're digging in the right spot the first time.
It happens a lot on the Ozark plateau — shallow soil over chert and limestone is normal ground around Rolla and St. James. Our equipment is set up to rip or hammer through rock so the line still gets to proper depth. Rock does add time to a job, which is one of the reasons access and soil are things we check during the free estimate.
We're based in St. James and serve Rolla, St. Robert and the rest of Phelps County plus the nearby towns. If you're out on rural acreage in the area with a well or a new build that needs water and power run to it, we're likely close by. Give us a call and we'll tell you.
