Hillside lot washing away or an old wall starting to lean? We build concrete retaining walls in Missoula that hold back slopes, handle clay soils, and survive hard Montana winters.

Concrete retaining walls in Missoula are built by excavating a trench below the frost line, pouring a deep concrete footing, forming and pouring the wall itself, then installing gravel drainage behind it - most standard residential walls take two to five days of active work from start to backfill.
Missoula sits in a mountain valley where freeze-thaw cycles and clay-heavy hillside soils make wall construction more demanding than in warmer markets. The South Hills, Rattlesnake, and Grant Creek neighborhoods all have sloped lots where proper wall construction is not just about looks - it protects your property from real damage. Many homeowners in these areas also need concrete floor installation work done alongside a new wall when they are regrading a basement or garage area.

These are the warning signs Missoula homeowners most often describe when they call us.
If soil is visibly moving downhill toward your foundation, driveway, or a neighbor's fence, the slope needs to be held in place. In Missoula's South Hills and Rattlesnake neighborhoods, this creep often gets worse every spring as snowmelt saturates the ground. A retaining wall stops that movement before it becomes a much more expensive repair.
If your current wall is tilting forward, showing horizontal cracks, or has gaps opening at the base, it is telling you something is wrong underneath. In Missoula's climate, freeze-thaw cycles put enormous stress on walls that were not built with deep enough footings or proper drainage. A wall that is leaning is one wet spring away from failing completely.
When water collects against your home after rain or snowmelt, a slope above is directing runoff toward your property. A retaining wall combined with proper grading can redirect that water away from your foundation, protecting your basement and reducing erosion over time.
Visible erosion - bare soil, exposed tree roots, or gravel washing off a slope - means the ground is moving. Missoula's spring runoff season can accelerate this quickly, especially on south-facing slopes that thaw fast. A retaining wall stops erosion at the source rather than just patching the damage each year.
We handle everything from permit application through final backfill and cleanup. Every wall we build starts with excavation deep enough to place the footing below Missoula's frost line - around 36 inches on a cold winter. We set forms, pour the wall, and install gravel drainage with weep holes behind the structure before backfilling in compacted layers. Skipping or rushing any of those steps is how walls fail in three to five years, and it is also how homeowners end up with expensive emergency repairs. For projects that include flat work near the base of a new wall, our concrete footings service covers the structural groundwork.
We also handle the City of Missoula permit process for walls over 4 feet tall, including any required drawings or plan review. If you are dealing with slopes near a property line or a drainage easement, we can advise you on what the city will need before we submit. Homeowners who want to create usable flat space on a hillside lot often pair a new retaining wall with concrete floor installation for a patio or garage slab at the base.
Best for homeowners with hillside lots who need to stop soil movement and protect their yard.
Right when an existing wall is leaning, cracking, or has failed drainage behind it.
Suits projects over 4 feet where the city requires drawings and inspection.
Good for steep lots where a single tall wall would need to be engineered or is too intrusive.
For any wall project where water management behind the wall is the primary concern.
Suits homeowners who want the wall to look finished and match their landscaping.
Missoula's hillside neighborhoods - the South Hills, Rattlesnake, and Grant Creek areas - sit on sloped lots where retaining walls are not optional upgrades. They are often the only thing keeping a yard from gradually sliding toward the street or a neighbor's property. The valley floor and lower hillsides also include areas of clay-heavy soil left behind by ancient Glacial Lake Missoula. Clay holds water and expands when wet, which puts extra lateral pressure on walls during spring snowmelt. A contractor who does not understand this will undersize the drainage or set the footing too shallow, and the wall will show it within a few years. We also know that Missoula's construction season is short - reliable concrete work runs from late April through October - so we plan schedules that do not push pours into risky shoulder-season temperatures.
We serve homeowners throughout western Montana, including Deer Lodge and Anaconda, where similar valley topography and frost conditions require the same approach. If you have a slope on your property that concerns you, call us before it becomes an emergency repair.
Call or submit the contact form and we respond within 1 business day. We schedule an on-site visit to walk the slope, assess the soil and drainage, and ask what you need the wall to accomplish. No commitment required at this stage.
You receive a written quote covering excavation, footing, wall, drainage, backfill, and cleanup. For walls over 4 feet, we handle the City of Missoula permit application before work begins - typically one to three weeks of lead time.
The crew digs the trench to frost-line depth and pours the concrete footing. This is the anchor that keeps the wall from shifting. In Missoula, that footing goes roughly 36 inches down - deeper than what contractors in warmer climates dig.
After the footing cures, we form and pour the wall, then install gravel drainage with weep holes before backfilling in compacted layers. Concrete reaches full strength over about 28 days - avoid heavy loads near the wall during that time.
Free on-site estimate. No obligation. We respond within 1 business day and pull all required Missoula permits.
(406) 317-4988We set every footing below the 36-inch frost line that Missoula's coldest winters demand. A wall with a shallow footing will heave and crack within a few years in this climate - ours do not.
We install gravel backfill and weep holes behind every wall we build. Proper drainage is the single most important factor in long-term wall performance, and it is one of the most commonly skipped steps in the industry.
We manage the entire City of Missoula permit process for walls that require it - drawings, application, and inspection coordination. Unpermitted walls are flagged during home sales and can require costly teardown and rebuilding. We make sure yours is fully above board.
Hillside lots in the South Hills and Rattlesnake neighborhoods present challenges that flat-lot work does not - steep access, clay soils, and drainage from above. We have built walls on these lots and know what they require. You can verify our Montana contractor license before signing anything.
Every wall we build is backed by local knowledge, honest pricing, and work that will still be standing straight in ten years. If you have questions about your project, call us - we are happy to talk through what you are dealing with before you commit to anything.
