Boulder retaining walls that hold the hill.
Engineered rock walls built by the ton across the Inland Northwest. We cut the grade, set the drainage, and place rock that stays put.
Rock walls are the whole business, not a side service.
WHAT WE BUILD
Most landscapers stack rock. We engineer it: excavation, base prep, drainage, and boulder placement handled by one crew with our own equipment.
Large boulder retaining walls
OUR SPECIALTY
Walls from two feet to over twelve, built with 1 to 12-ton basalt and granite. We key the base below grade, backfill with drain rock and geotextile, and set every boulder with an excavator thumb so the face locks instead of leaning.
- Typical height range
- 2 – 12 ft
- Boulder size
- 1 – 12 tons
- Base & drainage
- Keyed footing, drain rock, fabric
- Engineering
- Stamped plans over 4 ft
- Typical build time
- 2 – 5 days
Driveway & road cuts
Widen a driveway or carve a buildable pad without losing the hillside above it.
03Terraced landscape walls
Multi-tier walls that turn a slope you can't use into planted, walkable yard.
04Slope stabilization & erosion control
Failing bank, washout, or a wall someone else built wrong. We re-cut and rebuild.
05Commercial & subdivision
Plan-and-spec work for builders and developers. Bonded, insured, scheduled to your phase.
RECENT WORK
Walls we've built across the Inland Northwest.
Take a look at recent projects around Spokane, Colbert, Kennewick and North Idaho. Odds are we've built on a slope like yours.
How a wall happens
Five steps, no mystery, no change-order games.
-
01
Walk the site
We measure grade, check water, and tell you honestly if a wall is the right fix.
-
02
Fixed bid + plan
Linear feet, height, tonnage, drainage spec, and a date. One page, one number.
-
03
Cut & key the base
Excavate to competent soil, key the footing below grade, lay drain rock and fabric.
-
04
Set the rock
Boulders placed face-locked by excavator, chinked and battened back into the slope.
-
05
Backfill & clean
Grade behind the wall, restore topsoil, haul the spoils. Site leaves ready to plant.
Where we work
Two yards, one crew standard.
Spokane out of Colbert, Tri-Cities out of Kennewick. Anything within roughly 60 miles of either yard gets a same-week site visit.
