Excavation & Site Prep in Thornton, CO
Pads and slabs for garages and shops, utility runs, and foundation work for new construction across Thornton.
Pads, slabs and foundation work in Thornton
Thornton keeps growing, especially on its north and east sides, and a lot of what we do here supports new construction: foundation excavation, utility runs to new structures, and the pads and slabs that garages and shops sit on.
If you are adding a detached garage or a shop, we can handle the ground work from start to finish: strip and cut the pad, run the trench for power or water, set the base and pour the slab.

Building a pad that holds up
A slab is only as good as the ground under it. In the clay soils common across the north metro, that means removing unsuitable material, bringing in and compacting a proper base, and grading so water does not sit against the slab edge.
Permits and locates in Thornton
Garages, shops and larger slabs in Thornton often need a building permit from the City of Thornton. Before excavation starts we make sure Colorado 811 locates are in place.

Thornton FAQ
Can you build the pad and pour the slab for a new garage or shop?
Yes. Pad prep and the slab pour are some of our most common Thornton jobs, and doing both keeps the base and the concrete under one crew.
Do you run power or water trenches to a new shop?
Yes. We dig utility trenches to the route and depth required, then backfill and compact after the line is in.
Do you work on new construction in north Thornton?
Yes. Foundation excavation and site prep for new builds is core work for us anywhere in Thornton.
