Underground Utilities in Southeast Michigan

Example builds › Rock Solid Excavation › Services › Underground Utilities

Rock Solid Excavation handles the underground work that connects a property to its services — trenching for water, electric, and gas service lines, and sewer tie-ins to municipal systems. We plan around the utilities already in the ground, dig clean, and restore the surface so you'd hardly know we were there. In Michigan, what's buried has to survive frost and shifting clay, so compaction and depth matter. Freeze, thaw, repeat — built to take it.

What We Run

From a single service line to a sewer connection, we do the trenching and tie-in work that gets a property connected, on a new build or an existing one.

Trenching across a finished property can be a mess if it's done carelessly. We plan the route around what's already in the ground, dig efficiently, and put the site back together — proper backfill, compaction so the trench doesn't settle and sink later, and surface restoration so the lawn or drive recovers. Doing the compaction right is what keeps a trench from turning into a sunken line across the yard after the first freeze-thaw season.

How We Keep Disruption Down

On a new build, utility runs and the sewer tie-in get planned with the rest of the site work so everything fits — trenching gets done before the surfaces go down, and the connections are laid out to match how the rest of the site comes together. On an existing property, the challenge is working around what's already there — landscaping, drives, and other buried lines — with as little disruption as possible. Either way, John will walk the route with you first and lay out how the work will go.

In Michigan, depth isn't optional. Buried lines have to sit below the frost line and stay there, because a service line set too shallow can freeze, shift, or fail when the ground heaves. We dig to the right depth for what's being run, bed the line properly, and backfill in a way that protects it for the long haul. Freeze, thaw, repeat — built to take it. Getting the depth and bedding right up front is what keeps a buried line out of trouble for decades instead of becoming a problem after the first hard winter.

New Builds and Existing Properties

We work to keep disruption down — planning a tight route, digging efficiently, then backfilling, compacting, and restoring the surface. The trench line recovers, and proper compaction keeps it from settling into a sunken strip later.

Yes. Sewer tie-ins to municipal systems are part of what we do, planned around existing utilities and connected properly.

Depth and Frost

If a trench is backfilled loosely, the ground settles over time — especially through Michigan's freeze-thaw cycles — leaving a sunken line and sometimes stressing the buried service. Proper compaction prevents that, so we don't cut corners on it.

We're based in Fenton and serve Genesee, Oakland, Livingston, and Washtenaw County, including Flint, Grand Blanc, Linden, Holly, Hartland, Howell, Brighton, Milford, and the surrounding area.
