Foundation & Retaining in Boise, ID
Idaho's capital, where the high desert meets the foothills
Building on Boise's Foothills slopes and stepped Bench lots often means a retaining wall and a foundation cut that has to be right the first time. Iron Crest Earthworks excavates footings and wall bases to plan, builds a compacted, free-draining base that handles slope and freeze-thaw, backfills behind the wall, and coordinates cleanly with your foundation and concrete crews so the grade holds for decades.
What's included
- Foundation & footing excavation
- Basement & crawlspace digs
- Retaining-wall excavation & base
- Hardscape & paver base prep
- Backfill & compaction
In Boise, we take on foundation & retaining across the North End, the Bench, Southeast Boise & Warm Springs, and the rest of Ada County — sized to the lot and the access on each site.
Our process
How foundation & retaining works in Boise
- 01
Stake to plan
We work from your foundation or wall plans, confirm dimensions and depth, and quote it free.
- 02
Excavate to grade
Footings, basements, and wall bases are dug to the correct depth and dimension.
- 03
Prep the base
We place and compact base material so the foundation or wall sits on solid, level ground.
- 04
Backfill & compact
After the structure is in, we backfill in lifts and compact so nothing settles or pushes.
Every Boise job includes coordinating the permits Ada County requires and hauling debris off-site — we leave the lot clean and ready for what's next.
Working in Boise
Idaho's capital, where the high desert meets the foothills
Boise spreads from the Boise River and its Greenbelt up into the Foothills, mixing dense established neighborhoods with hillside lots and high-desert ground on the edges. Older parts of town carry decades-old structures, mature trees, and tight access; the bench and foothill margins bring slope, rock, and drainage to plan around.
Boise jobs run the gamut — gutting and tearing out aging structures on tight North End and Bench lots where access and neighbors matter, and grading or clearing hillside parcels on the foothill edge where slope and runoff drive the plan. We keep dust controlled and coordinate the City of Boise permits and utility disconnects these jobs require.

Do you haul off the debris after foundation & retaining in Boise?
Always. Every Boise job includes sorting, loading, and hauling debris off-site, so your Ada County lot is left clean — no pile left for you to deal with.
Do you dig foundations and footings?
Yes — foundation, footing, basement, and crawlspace excavation are core to what we do. We dig to your plan dimensions and depth.
Can you prep the base for a retaining wall?
Yes. We excavate and build a compacted base for retaining walls, which is critical on the valley's sloped lots.
Do you backfill after the foundation is poured?
Yes. We backfill in compacted lifts so the soil around your foundation doesn't settle or push against it.
