Foundation to finish grade for St. Louis metro jobs.
From residential basements in South City to commercial pads in Chesterfield, we run excavation jobs across the St. Louis metro. Equipment is sized to the site — we don't send a 36-ton into a residential back yard, and we don't send a mini-ex to move 500 yards.
The full scope,
one contractor.
St. Louis is the metro hub we serve most — jobs span everything from downtown utility work to suburban site development across the county line. We don't sub the work out — the same crew that quotes the job does the work.
Precise digs to plan depth and dimension. We work from engineered drawings and coordinate with your foundation contractor for clean handoff.
Stripping, clearing, stockpiling, and rough cut to get your lot ready for foundation, slab, or vertical construction.
When the bucket hits limestone, we switch to hydraulic hammer. We carry the right attachment and don't sub out rock work.
Excavated material is loaded and hauled in the same day. We manage disposal or stockpile to your specification.
Structural backfill placed in lifts and mechanically compacted. We don't leave settlement problems behind for your slab to find later.
Jon Jones is on-site for every excavation project. The person who quotes the job runs it.
Local conditions,
local expertise.
St. Louis project work spans a spectrum that no other metro quite matches — century-old utility corridors downtown, suburban foundation digs through glacial till and clay, and commercial redevelopment in tight corridors where every buried line has to be confirmed before a bucket moves. Aging infrastructure in South City and North County generates steady sewer and water repair calls, and the utility density in the downtown commercial core makes hydrovac the standard for any excavation near established rights-of-way.
Our process
in St. Louis, MO.
We work from your engineering drawings — plan depth, dimensions, setbacks, and utility conflicts reviewed before equipment moves. Any conflicts we spot on the drawing get surfaced before we dig.
Tight residential lots get the mini-ex. Production foundation digs get the full-sized fleet. We size equipment to the site — no oversized iron in a backyard, no undersized bucket on a 500-yard cut.
Dig to plan depth and dimensions. Spoils loaded same-day where possible or stockpiled to your specification. We don't leave excavated material piled against structures overnight.
We finish to your subgrade elevation and walk it with you or your foundation contractor before we leave. You get photos of depth and dimensions — clean handoff, fully documented.

How is excavation priced for jobs in St. Louis, MO?
Pricing depends on soil conditions, depth, rock presence, spoils disposal, and site access. St. Louis Metro has significant limestone in many locations, which adds hydraulic hammer time to some jobs. We quote every project individually after reviewing plans or walking the site.
Can J1S handle rock excavation in St. Louis, MO?
Yes. We carry a hydraulic hammer attachment and don't sub out rock work. When the bucket stalls on limestone — common across St. Louis Metro — we switch to the hammer and keep the job moving without calling in a third party.
Do you handle spoils hauling as part of the excavation?
Typically yes. We load and haul excavation spoils with our own trucks — one contractor for the full scope. Spoils can be hauled off-site to disposal or stockpiled on-site to your specification.
How long does a residential foundation excavation take near St. Louis, MO?
Most residential basement excavations in the St. Louis Metro area run one to two days depending on depth, soil, and whether rock is encountered. We give a realistic timeframe when we quote — and if conditions change mid-job, we communicate immediately.
