Nevada is a close-knit community of about 7000 in Story 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 in Nevada spans multiple eras: Small town core with 1960s-80s suburban expansion; median house age is approx. 45 years. That range means you'll find concrete block basement, poured concrete basement, crawlspace foundations across different neighborhoods — and many eventually need the engineered approach to foundation settlement. The dense glacial till in Nevada prevents quick drainage. Standing water against block foundations leads to significant lateral pressure and wall bowing.
Flat agricultural terrain in Story County; high density of glacial till in the subsoil. The flat terrain means water doesn't naturally drain away from foundations — it pools and presses. That's where stop seepage before it damages walls and flooring makes the difference. JLB provides 5 specialized services to Nevada homeowners: foundation repair, waterproofing, crawlspace encapsulation, drainage solutions, wall replacement, and more — all designed for the specific conditions in this area. Every job starts with a free estimate and an honest assessment — no pressure, no obligation.
Nevada at a Glance
Where Does JLB Provide Foundation Repair in Nevada, IA?
JLB provides foundation repair and waterproofing throughout Nevada and the surrounding Story County area. Our crews know every part of this community.
Why Are Nevada's Block Foundations Vulnerable to Story County Soil Pressure?
The homes in Nevada sit on a range of foundation types, each with its own vulnerabilities. Here's what our crews see most often in Story County.
Concrete block basement
Concrete block basements in Nevada use hollow-core masonry that's inherently weaker than poured concrete under lateral loads. The expansive clay in Story County presses against these walls every wet season, and over time the cumulative stress shows up as cracking, bowing, or step-pattern fractures.
Poured concrete basement
Poured concrete basements in Nevada are the most common type across Story County. They handle the clay soil better than block, but lateral pressure still creates vertical and diagonal cracks — especially near corners and window wells where the wall is weakest. Catching these early prevents water infiltration.
Crawlspace
Crawlspace foundations in Nevada trap moisture from Story County's clay soil, creating an environment where mold, wood rot, and structural sagging thrive. Full encapsulation with spray foam and vapor barriers is the permanent solution — and JLB seals both the crawlspace and the basement for twice the protection.

Numbers That Speak for Themselves
Cracks in Your Nevada Basement Walls?
The concrete block foundations common in Nevada develop predictable crack patterns under years of clay pressure. A free estimate from JLB identifies the cause and gives you a clear plan — before the cracks become a structural issue.
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.

Foundation Repair & Waterproofing Questions for Nevada Homeowners
The most common issues we see in Nevada are wall cracks (stair-step and horizontal patterns in block walls), basement water intrusion, uneven or settling floors, and doors or windows that stick. The dense glacial till in Nevada prevents quick drainage. Standing water against block foundations leads to significant lateral pressure and wall bowing. All of these trace back to how Story County's expansive clay interacts with the specific foundation types in your neighborhood. For homes with crawlspaces, insulate and seal for year-round comfort addresses the moisture side of the equation.
Foundation problems in Nevada correlate with housing age and foundation type more than specific neighborhoods. Areas with Small town core with 1960s-80s suburban expansion housing tend to have the most issues because those foundations have endured decades of Story County's clay pressure. That said, Story County's soil affects the entire city — we've done work in virtually every part of Nevada.
Story County's expansive clay undergoes dramatic volume changes with moisture. When wet, it swells and pushes against foundation walls with thousands of pounds of lateral force. When dry, it contracts and creates voids beneath footings. Flat agricultural terrain in Story County; high density of glacial till in the subsoil. This endless cycle causes progressive damage that compounds year after year if not addressed.
Foundation repair costs in Nevada vary widely based on the scope of damage and the solution needed. Minor crack repairs may cost $500-$2,000. Pier installation for settling foundations typically ranges from $5,000-$15,000. Full waterproofing systems run $3,000-$12,000. We provide free estimates with detailed, written estimates — no surprises and no pressure.
JLB provides 5 services to Nevada homeowners: foundation repair (push piers, wall anchors, carbon fiber), basement waterproofing (interior drainage, sump pumps, crack injection), crawlspace encapsulation (spray foam + vapor barriers for both crawlspace and basement), foundation wall replacement, and custom drainage plans based on your water flow.
