Des Moines Foundation Repairs & Waterproofing
Des Moines sits at the confluence of two rivers, and the neighborhoods closest to the Des Moines and Raccoon rivers deal with foundation conditions that the rest of central Iowa doesn't face at the same intensity. Seasonal flooding, saturated clay soils, and hard freeze cycles combine to put consistent pressure on basement walls, footings, and the concrete around the house. Bowed block walls, step cracks near windows, water tracking across the floor after storms, and settled driveways and walks are all common results.
Anchored Walls has been working on those problems in and around Des Moines since 1978. The company started with wall anchor systems for pushed-in basement walls and grew into a full foundation and waterproofing contractor serving central Iowa. Today their experienced crews handle foundation repair, basement waterproofing, crawl space encapsulation, concrete leveling, and egress window installation, with repairs backed by a Lifetime transferable warranty and a money-back guarantee.

Foundation Repair in Des Moines, IA
The housing stock across Des Moines spans more than a century, and the foundation problems here reflect that range. Older homes in neighborhoods like Beaverdale, Highland Park, and the South Side often have block or brick foundations that have been taking on clay soil pressure and freeze-thaw movement for decades. Newer construction on the expanding edges of Polk County isn't immune either. The expansive soils here put stress on poured concrete walls too, particularly after wet springs followed by dry summers.
The signs tend to show up in predictable patterns. In the basement, a horizontal crack running across a block wall usually means lateral soil pressure has been building outside. Stair-step cracks climbing the mortar joints point to settlement along part of the footing. A wall that looks straight from a distance but curves slightly inward through the middle has started to bow. Upstairs, doors that used to close cleanly and now rub at the top corner, or floors with a noticeable dip toward one side of a room, are often the first things homeowners notice before they've looked closely at the basement. Anchored Walls built its reputation in Des Moines on repairing pushed-in and bowing basement walls. For walls showing inward movement, their crews install steel wall anchors that extend into stable soil away from the foundation and connect to steel plates on the interior wall. The system can be gradually tightened over time to help restore wall position while preventing further movement. For settlement, they use helical piers or push piers to transfer the load down to stable bearing soil below the problem zone. Cracked sections are repaired, loose blocks reset, and weak spots reinforced so the wall carries the load properly again. Every job starts with an inspection. A specialist looks at the walls, floors, and grading around the house, explains what's happening in plain terms, and recommends a repair that fits what they actually see on that specific property.

Basement Waterproofing in Des Moines, IA
After a long rain or a fast snowmelt, water tracks in along the wall-floor seam, leaves damp patches in the middle of the slab, or pools near floor drains. Block walls develop bubbling or peeling paint. A musty smell settles into the space and doesn't clear for days. In finished basements the evidence shows up as swelling base trim, carpet that stays damp at the edges, or rust forming on stored items and metal posts.
Homes near the Des Moines and Raccoon rivers face that pressure more acutely during high water, but saturated clay pushes moisture through gaps, cracks, and footing seams across the city regardless of proximity to the rivers. Older Des Moines basements often have no interior drainage at all, so water that gets through has nowhere controlled to go. Anchored Walls installs interior drainage systems for Des Moines homes sized to the specific conditions in each basement. Their crews cut a channel along the inside perimeter at the footing, set drain lines in clean stone, and route water to a sump basin where a pump discharges it away from the foundation. Wall protection panels can be added to direct moisture seeping through block walls down into the drainage system before it reaches the floor. When a homeowner calls about a wet basement, Anchored Walls looks at where water is actually entering, how often it happens, and what's already in place before recommending a repair.

Crawl Space Repair in Des Moines, IA
A lot of Des Moines homes sit over open or partially open crawl spaces, and the humidity that central Iowa summers bring makes those spaces hard to control. Bare soil releases moisture into the air below the house, open vents let outside humidity in, and water that seeps along the foundation edges has nowhere to drain. The results show up above the crawl space as floors that feel soft or uneven underfoot, a musty smell that strengthens near interior walls and vents, insulation hanging down in clumps, and condensation collecting on ductwork and pipes.
Left unaddressed, that moisture works into floor framing, weakens wood over time, and can cause supports under the floor to lose bearing capacity. Anchored Walls repairs and encapsulates crawl spaces in and around Des Moines. Their crews seal the ground with a durable vapor barrier, close off vents and gaps that let outside air in, and install drainage and a sump system where standing water is present. Dehumidifiers sized for the space pull residual moisture from the air so humidity stays at a controlled level. Where floor framing has started to drop, support posts are added or adjusted to bring the structure back to proper bearing. The inspection covers the crawl space itself, not just the symptoms showing up in the rooms above it. Moisture levels, wood condition, support layout, and how water reaches the space are all part of what Anchored Walls looks at before recommending a repair plan.

Concrete Leveling in Des Moines, IA
Central Iowa's clay soils shrink and swell with the seasons, and that movement leaves voids under concrete over time. A sidewalk panel drops at one corner and catches your foot. Driveway slabs develop a lip at the garage that you feel every time you pull in. Front steps pull away from the porch and leave a gap that widens each year. Patios tilt back toward the foundation and hold water against the wall instead of draining away from it.
The slab itself is usually fine. The problem is what's underneath. Downspout washout, freeze-thaw movement, and soft spots near the foundation leave voids under the concrete, and once the support is gone the slab follows gravity. Anchored Walls levels settled concrete around Des Moines using a polyfoam lifting process. Small holes are drilled through the slab, expanding foam is injected underneath, and as it fills voids and cures it raises the concrete back toward its original position. A sunken sidewalk panel comes back up to meet the next one, a low driveway edge lifts at the garage, a tilted step returns to a safe, even surface. Safety is a consistent part of the conversation on these jobs. Uneven slabs create trip hazards and send water toward the foundation rather than away from it. Lifting the concrete with polyfoam addresses both problems at once.

Egress Window Installation in Des Moines, IA
Older Des Moines homes were built under different code requirements, and a lot of those basements have windows that are too small, too high, or otherwise insufficient for a finished living space. When a homeowner starts planning a bedroom, office, or family room downstairs, the question of how someone would get out in an emergency comes up fast.
Adding a properly sized egress window solves several problems at once. It provides a code-compliant escape route, brings real daylight into a finished room, and when done correctly keeps soil and water away from the new opening so you aren't trading one problem for another. Anchored Walls installs egress windows in Des Moines basements. That work includes excavating next to the foundation, cutting a clean opening in the concrete or block wall, setting the window unit, and installing a code-sized well with a ladder or built-in steps. Drainage at the bottom of the well ties into stone and a drain line so water doesn't sit against the wall. Inside, the opening is trimmed so the new window integrates cleanly with the finished space. Before any cutting starts, Anchored Walls looks at the basement layout, exterior grade, and which wall makes the most sense for light, safety, and access. The result is a window that looks planned, works with the house, and makes the lower level safer and more usable. Why Des Moines Homeowners Trust Anchored Walls. Anchored Walls has been working on Des Moines foundations since 1978. A lot of that early work came through referrals from homeowners who had watched a pushed-in basement wall get straightened and braced, then called back years later when drainage or crawl space issues came up. That kind of repeat business from the same neighborhoods builds up over decades, and it shows in how the company approaches a job. The work is done by experienced crews who work in central Iowa soils every day. The same people installing wall anchors on one job may be cutting an egress window or laying out an interior drain the next week. That experience matters when someone is explaining what's happening to your foundation, walking through repair options, and setting expectations before work starts. Repairs are backed by a Lifetime transferable warranty and a money-back guarantee on qualifying systems. For Des Moines homeowners, that combination means the company intends to stand behind the work for as long as the house is standing, whether the job is a wall anchor installation on the south side of the city or a drainage system in a basement closer to the river.

After getting bids and talking with a few different contractors regarding what we needed for waterproofing our basement, I was feeling pretty overwhelmed, anxious and stressed out. Elliott was a breath of fresh air. He's a very nice, respectful guy. He is very knowledgeable and was easy to talk to. After speaking with him, I felt more at ease and less anxious about the whole process. Because of Elliott, we plan to move forward with Anchored Walls for our basement waterproofing.
