Dug to spec.
Ready for forms.
Precise foundation excavations for slabs, basements, footings and retaining walls across Damascus, Happy Valley and Oregon City. Built to spec for your contractor or builder, handed off clean to the next trade.
Four kinds of foundation work
Slab & Stem Wall Excavation
The pad cut to elevation and the stem wall lines opened up, so concrete goes where the plans say it goes.
Basement & Crawlspace Dig Outs
Full depth dig outs with clean walls and a flat bottom, sized so the crew after us is not hand digging corners.
Footing Trenching
Footings trenched to the depth and width on the drawings, straight runs, square corners.
Retaining Wall Excavation
The cut behind the wall and the trench under it, prepped for whatever wall system your project uses.
A foundation is only as good as the hole under it
Every trade that follows us builds on our work. If the dig out is off, the forms fight it, the concrete order is wrong and the framing inherits the error. So we dig to the plans, check the grade as we go, and leave walls and bottoms the forms crew can work against without cleanup.
This is the part of the job where it helps that we speak the language of GCs and developers. Tight schedules, exact grades, clean handoff to the next trade, no babysitting required. And Nathan runs the iron himself on every dig, so the person on the controls is the owner whose name is on the work.
Homeowner building without a GC? Same standard. Send us what your engineer or builder gave you and we will walk you through the rest in plain English.
Foundation dig outs rarely travel alone
Most foundation jobs start with ground that is not ready and end with material that has to move. If the lot is still overgrown, lot clearing comes first. The wider dirt work around the pad is our excavation bread and butter, and the spoils leave on our own trucks through hauling and grading. One crew, one schedule, one bill.
Timing works the same as the rest of our work. We can usually walk the site within a few days of your call, and most residential dig outs start within one to two weeks depending on the season and the schedule. If your foundation is one lot in a bigger build, we plan the dig around your timeline instead of ours.
What builders and owners ask us
Can you dig a basement or crawlspace?
Yes. Basement and crawlspace dig outs are core work for us, alongside slab and stem wall excavation, footing trenching and retaining wall excavation.
Do you work from my builder's plans?
Yes. Send the plans with your address and scope and we dig to them. Depths, widths and elevations come off the drawings, and the site gets handed to the forms crew the way they expect to find it.
What do you need from me for a quote?
Your address, the scope and any plans or photos you have. From there we will walk the site and give you a straightforward quote with no surprises. Estimates are free.
Can a GC get a certificate of insurance before you start?
Yes. Beaver Excavation is fully licensed and insured in Oregon, and we can send a certificate of insurance to any GC or property owner who needs one on file before work begins.
Plans in hand? Send them over.
Free estimates. We can usually walk a site within a few days of your call.
