Every underground utility starts the same way: a trench dug to the right depth, in the right place, without hitting anything already down there. Roberts Excavation provides utility trenching for homeowners, electricians, plumbers, and builders within about 30 miles of Plainfield — service trenches for new homes, conduit runs to garages and barns, and open trenches cut, held safe, and backfilled around another trade's schedule. We run our own machines, so trench timing is ours to control, not a subcontractor's.
Safe trenching is process, not luck. We call CBYD 811 for markouts before every dig, hand-expose existing lines where the locates converge, and cut trenches to the depth each utility's code requires — with sand bedding and warning tape where the spec calls for them. Where codes and separation rules allow, we run multiple utilities in one coordinated trench, so your yard gets opened and closed once instead of three or four times.
Eastern Connecticut trenching means rock. Glacial till, boulders, and ledge show up in a lot of local trenches, and we run equipment sized to deal with it rather than stopping the job when the digging gets hard. Free estimates, straightforward scheduling, and a compacted, restored trench when we leave — not a settled rut across your lawn a year later.
