Sewer Line Excavation
Replacing a line that is past repair.
A camera goes down the line first, because the picture decides the job. A single offset joint or one crushed section is a spot repair and a short trench. A line that is bellied, collapsed, or has root intrusion through every joint gets replaced end to end. We locate the run and its depth before anything is dug, so the trench goes where the pipe is rather than where the plan says it should be.
Sewer line repair →Water Service Line Excavation
From the meter to the house.
The service line is the one nobody thinks about until the pressure drops or a patch of lawn stays green through a dry spell. Galvanized lines corrode shut from the inside and old polybutylene splits at the fittings. The replacement goes in below the local frost depth, bedded in sand rather than laid on rock, with a new shutoff where it enters the building so the next repair does not need the street.
Repiping →Gas Line Excavation & Installation
Buried runs to a shop, generator, grill or pool heater.
A buried gas run is sized for the appliance at the end of it and every appliance already on the system, which is the step most often skipped — a line that is one size light works perfectly until the second appliance fires. Tracer wire goes in with the pipe so it can be found again, the line is pressure tested, and it is inspected before the trench closes.
Gas lines →Underground Electrical Trenching
Power out to a shop, barn, well, pump or gate.
Burial depth depends on what is in the trench — direct-burial cable, PVC conduit and a feeder behind a breaker are each held to a different minimum, and the inspector measures it. We pull the conduit, set the sweeps so the wire can actually be pulled later, keep the required separation from the gas and water in the same trench, and land it on a panel sized for what the building will eventually hold rather than what it holds today.
Wiring & repairs →Utility Trenching
One trench, several utilities, done to spec.
Running water, gas, electric and low-voltage in a shared trench is cheaper than four trenches and is allowed, within rules about vertical separation, bedding and marking. Each utility gets its own bed and its own warning tape at the right height, and the backfill goes in lifts and is compacted rather than pushed back in and left to settle over the winter.
Culvert Installation & Repair
Driveway crossings and washouts.
A culvert is sized for the water the ditch actually carries in a hard rain, not for the pipe that happened to be there. One that is undersized, crushed at the inlet, or silted full sends the next storm across the driveway instead of under it. We set the invert so it drains, armor the inlet and outlet so the ends do not undercut, and rebuild the shoulder over the top.
Storm Drain Installation
Moving surface water off the property.
Surface water is collected at catch basins and carried to somewhere it can go — daylight on a slope, a dry well, or a legal tie-in. The whole job is grade: a line with a flat spot in it holds water, freezes, and fails at the flat spot. We shoot the grade rather than eyeball it, and size the basins and the pipe to the roof and paving area feeding them.
French Drains
Subsurface water, away from the foundation.
A perforated pipe in washed rock, wrapped in filter fabric, intercepting groundwater before it reaches a wall or a crawlspace. Fabric and clean rock are what decide whether it still works in ten years — a drain backfilled with native soil silts shut and becomes a buried pipe full of dirt. Where the water has nowhere to fall to, the trench feeds a sump instead.
