Rough grading
Cut and fill to bring the site close to design elevations, moisture-conditioned and compacted in lifts.
Services
Rough and fine grading in your neighborhood and across the Delaware Valley, with elevations checked against the plan before we call it complete.

Capabilities
Cut and fill to bring the site close to design elevations, moisture-conditioned and compacted in lifts.
Final shaping for lawns, slabs, paving and swales so water moves where it should.
We provide equipment and remediate soft spots identified during proofroll or testing.
Grades checked against plan with laser/rod (machine control where the job calls for it).
Grade sloped away from foundations and toward planned outlets.
Topsoil spread, raked and ready for seed or sod when included.
Process
Tell us the project, the property and the timing. We'll say plainly whether it's a fit.
We walk the site, follow the water, check access and note anything that needs review.
A written scope built for your project — inclusions, exclusions and assumptions spelled out.
Utilities marked, protection set, then the work — with check-ins, not surprises.
Grade and drainage verified with you, punch items closed, site left clean.

FAQ
Rough grade gets the earth close to design; fine grade is the final shaping that controls drainage and finish surfaces.
Often, yes — sometimes regrading is enough, sometimes it needs drainage. We'll tell you which after walking it.
We work across the Delaware Valley — Pennsylvania, New Jersey, Delaware and Maryland. Outside that? Ask — we'll tell you honestly whether it makes sense.
It depends on the job and the municipality. We'll tell you during scoping what's needed and who typically pulls it; engineered or permitted work is coordinated with your engineer or GC.
Yes. We coordinate proofrolls and compaction testing and address soft areas they flag.
