What we do

One contractor, from raw ground to finished pad

Most of our work starts before there is anything to look at — clearing, digging, stabilising and grading until a site is ready to build on. We own the iron and run our own crews, so the schedule is ours to keep.

Industrial & Commercial Sitework

Site clearing, building pads, grading and demolition — everything that has to happen before anyone pours concrete.

Excavation & Mass Grading

Mass excavation, earthmoving, soil stabilization and finish grading at any scale, from a single lot to a subdivision.

Underground Utilities Construction

Water, sewer, storm and franchise utilities — new installation, repair and relocation, from a house service to a municipal main.

Rock Crushing & Aggregate

Mobile crushing and screening on your site, plus concrete and asphalt recycling — usually cheaper than trucking aggregate in.

Buildings & Structures

Shops, pole and post-frame buildings, steel structures and custom homes — on ground we prepared ourselves.

Why WCI

No jobs too big or small

We have run mass grading on multi-acre industrial sites and we have dug a single footing for a shop building. Both get the same estimator, the same equipment and the same answer on the phone.
