Serving West Des Moines, IA and surrounding areas. (515) 706-9183
Cracked or bowing basement walls are a sign your foundation needs attention. We build concrete block foundation walls with proper waterproofing and drainage so your basement stays dry through Iowa winters and wet springs.
Foundation block wall installation in West Des Moines means stacking hollow concrete blocks with mortar to form the walls below your home, reinforcing hollow cores with concrete and steel where needed, and coating the exterior with waterproofing before backfilling soil against it. Most residential projects take three to seven days of active work, depending on the size of the wall and how much excavation is needed first.
West Des Moines has a large share of homes built in the 1950s through 1980s, and many of those original block foundation walls are now 40 to 70 years old. When cracks, moisture, or visible bowing appear, the underlying cause is almost always a combination of clay-heavy soil, Iowa freeze-thaw cycles, and aging or absent waterproofing. If your home also needs attention to related structural work, we can coordinate foundation repair at the same time to address multiple issues in a single project.
Cracks that run sideways across your block wall - especially near the middle - are a sign the wall may be bowing inward under soil pressure. In West Des Moines, the combination of clay soils and freeze-thaw cycles makes this pattern more common than in areas with sandier ground. A horizontal crack is more serious than a vertical one and should be evaluated by a professional sooner rather than later.
White, chalky deposits on your block wall are called efflorescence - mineral salt left behind when water moves through the blocks and evaporates. It is a reliable sign that water is getting through your wall even if you have not seen standing water yet. In West Des Moines, this often shows up after spring thaw or heavy rain when groundwater levels rise and push moisture through aging block walls.
A musty smell that does not go away, even during dry weather, is often caused by moisture moving slowly through block walls. This is especially common in older West Des Moines homes where the original exterior waterproofing has degraded over decades. If the smell gets worse in spring or after rain, your block walls are likely the source.
Walk along your basement walls and look closely at the mortar lines between each block. If you see gaps, crumbling, or sections where mortar has fallen away entirely, the wall has lost some of its structural integrity and its ability to keep water out. This type of deterioration is normal in homes 40 or more years old - which describes a significant portion of West Des Moines's housing stock.
We handle new foundation block wall construction for additions, crawl spaces, and full basements, as well as partial wall replacements where damaged or failing sections need to come out and be rebuilt. Every installation includes exterior waterproofing and a drainage layer at the base of the wall - two steps that are often skipped by contractors looking to cut costs but that make the difference between a dry basement and a wet one. Where the design calls for it, hollow block cores are filled with concrete and reinforced with steel rods to add wall strength against lateral soil pressure.
Foundation block wall work often connects naturally to other projects. Some homeowners use a new foundation wall as the starting point for a larger outdoor project, including a custom outdoor kitchen masonry structure built on a solid concrete footing nearby. Others come to us specifically to address existing structural concerns through foundation repair before adding living space below grade.
Best for homeowners adding a basement, crawl space, or below-grade addition who need a structurally sound block wall built from the ground up.
Best for homeowners with isolated sections of damaged, bowing, or heavily cracked block wall that need to be removed and rebuilt rather than patched.
Best for homeowners with an existing block wall that is letting water through and needs exterior waterproofing and a drainage system installed to stop it.
West Des Moines sits on clay-heavy soil that holds water and swells when wet, then contracts when it dries. That movement puts constant lateral pressure on foundation walls, and without proper drainage it can lead to bowing or cracking even in a well-built wall. Iowa winters compound the problem - ground temperatures drop hard enough to freeze soil to depths of 36 to 48 inches in a bad year, expanding water-saturated clay against your foundation with real force. The city's spring flooding risk, tied to snowmelt and the Raccoon River watershed, means elevated groundwater is a regular seasonal condition here, not an occasional one. The Portland Cement Association publishes the technical guidance we follow for block wall construction in these conditions, covering waterproofing requirements and drainage system design for below-grade masonry.
Homeowners in Altoona and surrounding eastern suburbs reach out to us regularly about foundation walls on homes from the 1960s and 1970s that are showing signs of age. We also serve homeowners in Johnston who are finishing basements or adding below-grade living space and need a foundation wall inspection or partial replacement before the project can move forward. The City of West Des Moines requires permits for foundation work, and we handle the application and all scheduled city inspections as part of every project.
We respond within one business day. Tell us what you are seeing - cracks, moisture, or a new addition plan - and we will schedule a free on-site visit. Phone estimates are not reliable for foundation work because every house is different.
We inspect the existing foundation, look for signs of water intrusion or soil movement, and measure the scope. You receive a written proposal within a few days that covers excavation, block work, waterproofing, drainage, permit fees, and cleanup - no hidden add-ons.
Once you approve the proposal, we apply for the required City of West Des Moines permit. This typically takes one to two weeks. Use that time to clear the work area - we will tell you exactly how much clearance the crew needs around the foundation.
The crew excavates, lays the block wall, applies exterior waterproofing, installs the drainage layer, and backfills the soil. The city inspector signs off at the required stage - we handle scheduling. Mortar reaches full strength in about 28 days, but your basement is usable well before that.

(515) 706-9183Many contractors treat exterior waterproofing and drainage as optional line items. We include both on every foundation block wall project because skipping them is the most common reason basements stay wet after new wall work. You should not have to ask for these - they are part of every proposal we write.
We apply for all required City of West Des Moines building permits before the first shovel goes in the ground. A permitted project means a city inspector independently verifies the work meets code - which protects your investment and creates a paper trail that matters when you sell your home.
Central Iowa's combination of expansive clay soil and deep freeze-thaw cycles creates conditions that crack block walls in specific, predictable ways. We have worked on foundations across the Des Moines metro long enough to know what those conditions require - proper footing depth, the right mortar mix, drainage designed for clay, and waterproofing that holds up to seasonal groundwater rise.
Surprise add-ons are one of the most common frustrations in foundation work. Our written proposals itemize excavation, block work, waterproofing, drainage, permit fees, and cleanup so the number you approve is the number you pay. If something changes during the job, we tell you before the work is done - not after.
Every one of these proof points comes down to one thing: we do the work correctly the first time. Foundation walls are not a project you want to do twice, and homeowners across West Des Moines call us because our proposals are thorough, our work is permitted, and the result holds up through Iowa winters.
