The first bucket of dirt on a Cheney lot says a lot about the house you can afford. Sometimes it comes up brown silt for six feet. Sometimes the teeth scrape, bounce, and stop a foot and a half down on black basalt, and the budget conversation changes on the spot. This is channeled scabland country, where the Ice Age floods scoured the soil off old lava flows, and the rock can be deep under one lot and right under the sod next door.
Domex Construction builds custom homes here under Washington contractor license DAVYDCI833NC. Bring us a lot and a wish list and we'll develop the design with you, adding a drafter or architect and an engineer as the house needs them. Or hand us plans from your own designer, or a stock set, and we'll price and build them as drawn, with the foundation adjusted to the ground we actually find. Nine years in business, 32 years of combined crew experience, fully insured.
Shallow Basalt and What It Does to a Foundation
Sound basalt carries a footing better than almost any soil. The trouble is getting into it: a machine that digs silt in an afternoon has to chip rock for days. When the pits show rock, there are three honest options:
- Break it. A hydraulic breaker on the excavator fractures the rock so it can be dug out. Slow work, billed by machine time.
- Build on it. Footings can bear directly on cleaned rock, stepping to follow its surface instead of cutting a level trench through it. It takes an engineer's detail and is often the cheapest answer.
- Rethink the basement. A full basement that pencils out on a silt lot becomes the most expensive room in the house when all eight feet of it are rock. A crawlspace, a partial basement where the rock drops away, or a house set higher on imported fill moves that money into rooms you'll see.
Basalt also changes where water goes. Snowmelt soaks through the topsoil, hits rock, and runs along its surface until it finds an opening, and a basement wall cut into that layer is one. Footing drains, a path to daylight or a sump, and backfill that sheds water get designed in from day one, not after the first wet March.
Trenches, Test Pits, and Utility Runs
Water lines and sewer laterals have to sit deep enough to stay out of the frost, and every foot of trench through basalt is breaker work. A house pushed far back from the street for privacy can cost more in trenching than the setback is worth. Where test pits find deeper soil along one side of the lot, utilities go there. Broken rock can't go back against the pipe, so lines get bedded in imported sand.
That's why our Cheney projects start with an excavator, not a floor plan. A few hours of test pits where the house, utilities, and any drainfield will go tells you more about the budget than a listing will.
Town Lot or Acreage Outside Cheney
Inside city limits, the City of Cheney issues the permit and the house ties into city water and sewer. The questions become setbacks, lot coverage, and how deep the sewer main runs compared with the rock on your lot. Older lots near campus run tight, so a two-story plan often fits better than a long ranch.
Past city limits the job grows. Spokane County issues the building permit and the Spokane Regional Health District reviews well and septic. Shallow soil over rock is exactly what can rule out a standard drainfield, so the soil evaluation comes before design, and the system the district allows can decide where the house sits. The well gets drilled into basalt, and nobody can promise its depth until the rig is done. Add power from the road, a driveway that carries a loaded concrete truck, and often a shop.
Open ground also means wind. We put the garage or shop on the weather side where the site allows and keep the entry out of the prevailing blow. The envelope gets what our siding crews in Cheney give every exposed wall: taped wrap seams, flashed openings, cladding fastened for gusts. Exterior work is where Domex started.

Getting a House Out of Scabland Ground
- Dig before you draw. Test pits at the footprint, utility route, and drainfield site, with rock depth recorded at each.
- Design to the rock. Drawings developed with you, or your plan set adjusted: crawlspace or basement, stepped footings, drainage, engineered details where footings bear on basalt.
- Permits by jurisdiction. City of Cheney for in-town lots; Spokane County plus the Spokane Regional Health District for acreage.
- Excavation and utilities. Breaking, sand-bedded trenches, footing drains, and foundation inspections, with rock work tracked against the allowance in your contract.
- Frame, close in, finish. Structure, a wind-tight envelope to Washington's energy code, systems, finishes, and a walkthrough against the written scope.
Rock and Lot Questions From Cheney Buyers
Can I find out how deep the rock is before I buy?
Yes. Ask the seller for permission to dig test pits, or make the purchase contingent on them. A few hours of excavator time is small next to a foundation surprise.
Do I have to give up on a basement?
Not necessarily. Where rock sits deep or drops away across the lot, a basement or walkout works. Where it's shallow everywhere, we'll price breaking it next to a crawlspace and let you decide what the room is worth.
Will you blast?
Blasting is a licensed specialty with its own permits and neighbor concerns, and on a town lot it's rarely worth it. Mechanical breaking, or footings designed to sit on the rock, handles most of what we see.
Does the rock affect septic on acreage?
Often. A drainfield needs enough suitable soil over the rock, and the health district decides what system your parcel gets. That answer can move the house, so we get it early.
How do you price rock nobody can see yet?
From the test pit results, with a written allowance for rock excavation and a stated rate beyond it. You'll know how a surprise gets priced before the first bucket goes in.
