Your satisfaction isn't just a goal—it's our promise. We'll work with you until every detail is exactly right. That's the Green Thumb difference.
Built for Iowa Freeze-Thaw
Iowa's clay-heavy soil holds water, and every winter that water freezes, expands, and pushes on your wall. Most retaining walls that fail here weren't built wrong on the outside — they were built wrong underneath.
What winter does vs. how we build
Winter
Water gets trapped behind the wall
How we build
Drainage stone and perforated tile carry it away before it can freeze.
Winter
Frozen soil heaves the base
How we build
We set a compacted aggregate base below frost depth.
Winter
Saturated clay pushes the wall forward
How we build
Geogrid ties the wall into the soil behind it on taller walls.
Winter
Fine soil clogs the drainage
How we build
Filter fabric keeps clay out of the stone so drainage keeps working for decades.
The walls we replace usually failed from missing drainage or an undersized base — not the block itself.
Permitting note: Taller retaining walls (and walls supporting a surcharge like a driveway or pool) typically require a building permit and engineered drawings in Central Iowa cities. The exact threshold varies by municipality, so we confirm with your city's building department on every project that's close to the line — and we handle the filing as part of the job.

Retaining Wall Materials We Install
Choose the right material for your property, budget, and style. We build every type with the same attention to drainage, engineering, and long-term durability.
Timber Retaining Walls
Pressure-treated timber walls offer a warm, natural look that blends beautifully with gardens and wooded lots. They're ideal for shorter walls under 4 feet, garden beds, and rustic landscape designs. Timber is cost-effective, easy to work with, and creates a charming organic aesthetic.
Best for: Garden beds, short slopes, rustic or cottage-style landscapes
Concrete Block Retaining Walls
Interlocking concrete blocks provide exceptional strength, clean lines, and long-term durability. These walls resist Iowa's freeze-thaw cycles, require minimal maintenance, and come in a variety of textures and colors to match your home's style. Perfect for structural loads and modern designs.
Best for: Structural walls, modern homes, tall slopes, driveways
Natural Stone Retaining Walls
Nothing beats the timeless elegance of natural stone. Boulder and fieldstone walls deliver unmatched curb appeal and can last a lifetime when properly built. Each stone wall is unique, offering a high-end, custom look that increases property value and creates a stunning focal point.
Best for: Premium landscapes, curb appeal, properties needing a custom look
Project Types We Build
Most of our retaining-wall work is large-scope: structural walls, terraced systems, and erosion control on the kind of sloped and walkout lots that are common across the Des Moines metro. We design for what your site actually needs — not a one-size package.
Segmental Block Walls
Versa-Lok, Allan Block, and similar engineered systems — the workhorse for 3–10 ft structural walls with geogrid reinforcement.
Boulder & Natural Stone
Iowa fieldstone and limestone boulder walls when the look needs to read organic and the wall is acting as much as landscape as structure.
Poured Concrete Walls
When height, load, or a tight property line calls for engineered cast-in-place — we coordinate with the engineer and excavator.
Tiered / Terraced Systems
Multiple shorter walls stepped up a hillside — usually the right answer when a single tall wall would require expensive engineering and a permit.
Erosion Control on Walkout Lots
Common on newer metro subdivisions where the builder left an aggressive grade behind the foundation — we re-grade, wall, and re-establish positive drainage.
Materials & When We Use Them
Segmental concrete block
Most cost-effective structural option, freeze-thaw rated, widely available in finishes that match metro architecture.
Natural stone & boulders
Higher cost, longer install, unmatched look — best for prominent front-yard and garden walls where the wall is part of the design.
Poured concrete
Strongest, smallest footprint per height — used when a tall, engineered wall is unavoidable or property lines are tight.
Drainage stone & filter fabric
Behind every wall: clean 3/4″ washed stone, perforated drain tile, and non-woven filter fabric. This is what keeps a wall standing — not what's visible from the street.
Geogrid reinforcement
Manufacturer-spec geogrid layered into the backfill on taller walls — non-negotiable on anything load-bearing.

Retaining Wall Installation FAQ — Des Moines & Central Iowa
How much does a retaining wall cost in Des Moines?
Typical Des Moines retaining wall projects range from about $3,800 for a 40-linear-foot front-yard replacement up to $22,000+ for a multi-tier backyard rebuild with integrated drainage. Price depends on wall length, height, materials, site access, and soil conditions. We provide free, detailed written estimates so you know exactly what to expect before any work begins.
How long does retaining wall installation take?
Most residential retaining wall projects are completed within 2 to 5 business days. Small garden walls may take just 1–2 days, while larger structural walls or terraced systems can take up to a week. Timeline depends on wall size, material, weather, and site conditions. We give you a clear schedule upfront and stick to it.
What is the best material for a retaining wall?
The best material depends on your goals, budget, and property. Concrete block is strongest and most durable for tall structural walls. Natural stone offers unmatched beauty and curb appeal. Timber is affordable and ideal for shorter, decorative walls. During your free estimate, we'll assess your site and recommend the right material for your specific needs.
Do I need a permit for a retaining wall in Iowa?
In most Des Moines-area jurisdictions, retaining walls over 4 feet tall require a permit. We handle all permitting, zoning checks, and HOA approvals as part of our service. You won't have to worry about paperwork — we ensure your wall is built to code and fully compliant with local regulations.
How do I know if I need a retaining wall?
You likely need a retaining wall if you notice soil washing away after rain, cracks in your foundation, sloping or uneven yards that are hard to mow, or water pooling near your home. Even if erosion seems minor now, it usually worsens over time. A free assessment from our team can confirm whether a wall is the right solution.
Are you a licensed retaining wall contractor near me in Des Moines?
Yes — Green Thumb Outdoor Solutions is a fully licensed and insured retaining wall contractor based in Des Moines, serving Ankeny, West Des Moines, Urbandale, Johnston, Waukee, Clive, Altoona, and the entire metro. Every retaining wall installation is built to code with general liability and workers' comp coverage on site.
Do you repair or replace failing retaining walls?
We do. If your existing wall is leaning, bowing, cracking, or pushing outward, our retaining wall builders will assess whether it can be rebuilt in place or needs full replacement. Most failures come from poor drainage or an undersized base — we fix the root cause so the new wall doesn't repeat the problem.
How tall a retaining wall can you build?
We build everything from short garden walls to multi-tier engineered systems. Once a wall starts approaching the height your city flags as requiring an engineered design, we coordinate a stamped plan and permit before we break ground.
What's behind the wall matters — what do you use?
Clean 3/4″ washed drainage stone, non-woven filter fabric against the soil, perforated drain tile at the base daylighted to grade, and compacted backfill in lifts. On taller walls we layer geogrid reinforcement per the block manufacturer's spec.
Can you terrace a steep slope instead of one tall wall?
Often that's the right call. Two or three shorter walls stepped up a hillside can avoid engineering requirements, plant out more beautifully, and cost less than one tall structural wall. We design for the slope you actually have.
How long will the wall last?
A properly built segmental block or natural stone wall — correct base, drainage, and reinforcement — should outlast the homeowner. The walls we replace usually failed because of missing drainage or undersized base, not the block itself.
