A retaining wall holds back soil, controls slope, and protects your property from erosion. In Des Moines, these walls face serious pressure from multiple directions. Iowa's heavy spring rains saturate the soil behind the wall and add enormous weight. Winter freeze-thaw cycles push against the wall's face from the front. Clay-heavy soils expand when wet and contract when dry, creating a constant cycle of lateral pressure. A retaining wall that is not built to handle these forces will crack, lean, and eventually fail. DSM Concrete Pros builds concrete retaining walls throughout the Des Moines metro, designed to stand up to exactly these conditions.
What Makes Retaining Walls Fail in Iowa
Most retaining wall failures in Des Moines come down to two problems — poor drainage and inadequate structure. Both are preventable with the right design and installation process.
Drainage is the biggest factor. When water builds up behind a retaining wall and has no place to go, the pressure on that wall increases dramatically. Iowa gets significant rainfall throughout the year. Spring rains are especially heavy and come fast. If the retained soil becomes saturated and water pressure builds with no relief, even a well-built wall can crack or bow outward.
The second problem is structural. A retaining wall needs to be sized and reinforced for the height of soil it holds and the conditions it faces. A wall that is too thin, lacks proper reinforcement, or sits on an inadequate footing will not last. In Iowa, where frost pushes 40 inches deep, and clay soils shift with moisture levels, the structural demands on a retaining wall are higher than in milder climates. Cutting corners on footing depth or reinforcement in Des Moines leads to walls that fail within just a few years.

How DSM Concrete Pros Builds Retaining Walls
Every retaining wall project starts with a site evaluation. DSM Concrete Pros looks at the slope, the soil type, the height of the wall needed, and what sits above and below the retained area. That information shapes every decision about footing depth, wall thickness, reinforcement, and drainage.
Footings go below the frost line on every wall we build. In Des Moines, that means setting footings at least 42 inches below grade. A footing above the frost line will heave with the ground during winter freezes. That movement transfers directly into the wall and causes cracking and tilting over time. Proper footing depth is non-negotiable in Iowa's climate.
Wall thickness and reinforcement depend on the wall height and the soil pressure it must resist. Taller walls carry more load and require more concrete and more rebar. DSM Concrete Pros sizes each wall for the actual conditions on site, not a one-size-fits-all template.
Drainage is built into every wall we install. We place a gravel drainage layer directly behind the wall and install drain tile at the base to carry water away from the retained soil. Weep holes or drainage outlets are included so that any water that does build up has a clear path out. This step is what separates a wall that lasts from one that fails after a few Iowa spring thaws.
Concrete Retaining Walls vs. Other Materials
Builders pick from wood, brick, or stone to construct these sturdy walls. You will mostly see block, wood, and concrete across Des Moines. Each path has trade-offs. Learn what they are so you can choose wisely.
Wood provides the lowest entry price for your new wall. They happen to have a very brief life cycle. Wood retains moisture, especially in Iowa's wet springs, and it eventually rots. You can count on timber structures to last roughly fifteen years. Once they hit that twenty-year mark, they generally need to be replaced. Des Moines weather puts timber walls through the wringer. The constant rain and cycles of freezing and thawing rot the wood much faster than in dry climates.
Segmental block walls use interlocking concrete blocks stacked in a battered pattern. Homeowners rely on these because they handle daily household tasks with ease. Size matters here. Added height reduces total stability. Taller walls built from segmental block require engineering and geogrid reinforcement to maintain stability.
Poured concrete walls stand up to pressure better and last longer than other building materials. A properly built concrete wall handles heavy soil loads, resists Iowa's freeze-thaw pressure, and lasts for decades without the maintenance demands of timber or the height limitations of block. For walls that carry significant loads, sit near structures, or need to hold back substantial slopes, poured concrete is the right choice.
Retaining Walls That Add Value to Your Property
A well-built retaining wall does more than hold back soil. It creates usable flat space on sloped properties. It defines outdoor living areas. It protects landscaping, driveways, and foundations from erosion. In Des Moines, where spring runoff can move a surprising amount of soil in a short time, a retaining wall protects real value.
DSM Concrete Pros finishes retaining walls to suit the property. Exposed concrete can be left with a natural form finish or given a textured surface to match surrounding hardscaping. We can also incorporate decorative wall elements in visible areas of the yard or near the front of a property.
A retaining wall built by DSM Concrete Pros is built to last. We do not skip footing depth to save time. We do not skip drainage to cut costs. We build walls the way they need to be built in Des Moines — with the right structure, the right materials, and a drainage system designed for Iowa's climate.
