Learn MoreFoundation Repair and Waterproofing for Pella's Older Homes
Pella is a close-knit community of about 10000 in Marion County. The homes here may not number in the tens of thousands, but they sit on the same aggressive clay soil that affects the entire Des Moines region — and they face the same foundation and waterproofing challenges as any home in the metro.
The housing stock in Pella dates primarily to the Unique mix of meticulously maintained historic European-style homes and stable 1970s-2000s residential growth.. Most homes sit on stone foundation and concrete block basement and poured concrete basement foundations — construction methods that were standard for the era but weren't designed to handle the soil movement we now understand. Pella's high property values make foundation maintenance a priority. Aging block basements are susceptible to moisture seepage from the expansive clay common in Marion County. When the damage shows, homeowners here need underpinning that bypasses problem soil completely.
High prairie plateau between the Des Moines and Skunk Rivers. Proximity to water means higher water tables and more hydrostatic pressure on foundations — making waterproofing designed for heavy clay soil essential for many homes. JLB provides 5 specialized services to Pella homeowners — from foundation stabilization to drainage systems — each designed for the unique soil and moisture conditions here. Every job begins with a free estimate.

How Does Marion County's Clay Affect Pella's Stone and Block Foundations?
The homes in Pella sit on a range of foundation types, each with its own vulnerabilities. Here's what our crews see most often in Marion County.
Stone foundation
Pella's oldest homes often sit on limestone or stone foundations — hand-laid masonry that predates modern engineering. These walls are porous, the mortar is lime-based, and decades of Marion County's clay pressure have taken a toll. Water intrusion, mortar deterioration, and inward leaning are common.
Concrete block basement
Concrete block foundations are common in Pella's pre-1950s homes. After decades of lateral pressure from expanding clay, the mortar joints weaken and walls begin to bow inward. Horizontal cracks near the midpoint of the wall are the classic warning sign — and they need professional attention before the wall fails.
Poured concrete basement
Poured concrete basements throughout Pella are strong, but they're in a tough spot — Marion County's clay soil and the area's high water table create persistent hydrostatic pressure. Cracks that start as hairline fractures become active water channels once the soil is fully saturated during spring thaw.

Catching foundation and waterproofing problems early saves thousands of dollars in repairs. If you see any of these in your Pella home, it's time to call for a free estimate.

Numbers That Speak for Themselves
Pella's Older Homes Deserve a Professional Eye
Foundations built before the 1950s have been absorbing soil pressure for over 70 years. If your Pella home is showing cracks, sticking doors, or basement moisture, a free estimate tells you exactly what's going on — before it gets expensive.
Not Sure What You're Dealing With?
Click any symptom below to learn what it means, what's likely causing it, and how we can help. Most of these are more common — and more fixable — than you'd think.
Diagonal, stair-step, or horizontal cracks in drywall, plaster, or brick usually trace back to soil movement beneath your foundation. The heavy clay soils in the Kansas City and Des Moines metros expand and contract seasonally, which can shift your foundation over time. The good news: this is very fixable with the right approach.
Water entering through floor joints, wall cracks, or seeping through porous concrete means groundwater pressure is pushing moisture into your basement. An interior drainage system and sump pump can solve this permanently — and we can usually have it done in a day or two.
When a foundation settles unevenly, it can shift your home's frame just enough to make doors and windows bind. This is one of the earlier signs of foundation movement — and catching it early often means a simpler, less expensive repair.
That musty smell is moisture. Up to 40% of the air in your home rises from below — from your crawlspace and basement. If there's excess humidity down there, it affects your whole home. Encapsulation seals it out, and you'll notice the difference in your air quality right away.
Floors that slope toward the center or an exterior wall usually mean the support structure underneath needs attention. Push piers can stabilize your foundation and often lift it back to level — giving your floors a second life.
When soil washes out or compacts beneath a concrete slab, the slab drops and becomes uneven. Polyjacking uses expanding polyurethane foam to fill the void and lift the concrete back to grade — usually in under a day, with no heavy equipment needed.
Water collecting near your foundation means your grading or drainage isn't directing water away effectively. French drains, regrading, extended downspouts, and drain pipes can redirect water away from the house — protecting your foundation for the long haul.
A basement wall that has bowed more than 2 inches inward, shifted off its footing, or shows multiple structural cracks may have moved beyond what bracing can fix. When carbon fiber straps, I-beams, or wall anchors are not enough, the wall needs to be removed and rebuilt with reinforced concrete. This is the last resort — but it is the permanent fix when the wall itself is compromised.

However, they're absolutely worth repairing — modern engineering solutions like push piers, wall anchors, and carbon fiber reinforcement can stabilize and extend the life of these foundations for decades.
Yes. High prairie plateau between the Des Moines and Skunk Rivers.
