Learn MoreWhy Do Properties Here Need Structural and Waterproofing Work?
Johnson County sits on the Wymore-Ladoga clay complex — 60–80% clay rated "very high" shrink-swell. That ground cycles pressure against basement walls year after year. Split-levels from the 1970s–1990s are especially vulnerable, and even 2000s construction shows early settlement from disturbed backfill.
Beneath the clay, a Peorian loess layer loses bearing capacity when saturated — creating conditions for both bowing walls and settlement on the same property. JLB evaluates each lot's conditions and drainage before recommending targeted solutions.

How Does Johnson County Clay Affect Local Structures?
Two common basement types here react differently to the aggressive local clay.
Poured Concrete Basement
Poured walls handle lateral pressure better than block but still develop cracks from settlement. Solutions include epoxy injection and pier underpinning.
Concrete Block Basement
Common in 1960s–1980s builds. Hollow-core block is vulnerable to lateral clay pressure, showing horizontal cracking along mortar joints. I-beams or anchors address the displacement.
What Warning Signs Should You Watch For?
These indicators worsen with each wet-dry cycle. If you spot any of them, schedule a free inspection before damage escalates.

Numbers That Speak for Themselves
Structural Damage Won't Stop on Its Own — Get Ahead of It
Every wet-dry cycle puts more pressure on your property. If you've noticed cracks, sloping floors, or water in the basement, a free inspection tells you exactly where things stand. Contact us today.
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.

What Our Customers Say
"We had cracks running up our walls and doors that wouldn't close. JLB came out, explained exactly what was happening with the soil under our house, and had the piers installed in two days. Floors are level again. Wish we hadn't waited so long."
"Three other companies gave us the runaround. JLB showed up, did a thorough inspection, and gave us a straight answer. The repair held up through an entire Missouri winter with zero new cracking."
"Our crawlspace was a mess — moisture, mold, the works. JLB encapsulated it AND spray-foamed our basement in the same project. The difference in our home's air quality is incredible. Great value for the price."

Questions From Local Homeowners
Expansive clay drives cracking in both poured and block basements, bowing walls in 1970s–1980s split-levels, and settlement that shows as sticking doors or stair-step cracks in brick veneer.
Steel piers are driven through the clay to load-bearing strata, then hydraulic pressure lifts the structure back to grade. Displaced walls are braced with I-beams or anchors depending on severity.
The local Group D clay sheds rainwater instead of absorbing it, building hydrostatic pressure against walls. JLB installs perimeter drain tile and sump systems to intercept water at the footing.
Yes — high rainfall on clay holds moisture against your property, and the stack effect pulls that damp air upstairs. Encapsulation with sealed vents and a dehumidifier drops humidity below the mold threshold.
Wall cracks, doors that stick, sloping floors, and water in the basement after rain all warrant professional evaluation. Early diagnosis prevents escalating damage and costs.
Steel piers for settlement, I-beams and anchors for wall displacement, drain tile and sump systems for water intrusion, crawlspace encapsulation, and polyurethane slab lifting. Every project includes a transferable warranty.
