Excavation & Site Prep in Arvada, CO
Foundation excavation, backfill and final grade, plus trenching for utilities to new structures across Arvada.
Foundation work in Arvada
Arvada ranges from established neighborhoods near Olde Town to newer development on the northwest side. Across all of it, our work centers on the foundation: digging it, backfilling it properly once the walls are up, and setting final grade.
We also trench for utilities to new structures such as detached garages, shops and accessory buildings, so water, sewer or power gets where it needs to go.
What we do in Arvada
Why backfill matters
Backfill that is dumped in and left loose will settle, and settled backfill around a foundation sends water straight toward the walls. We place and compact backfill in lifts, then set final grade so the ground slopes away from the house.
