Where the Iowa River carved the limestone bluffs that made Iowa Falls the Scenic City, those same river terraces and weathered Hardin County till test old basements daily — so JLB brings foundation repair and basement waterproofing to every home in town.

Up on the Iowan Surface uplands toward the US-20 corridor, Iowa Falls homes settle unevenly as the weathered till and clay dry and swell with the seasons, opening stair-step and diagonal cracks in pre-1940 walls near downtown. JLB stabilizes these foundations with steel push or helical piering and wall braces, restoring level footing across both the historic core and newer builds.
Because much of this Scenic City sits on the lower terraces the Iowa River carved between its limestone bluffs, basements here fight a stubbornly high water table and spring seepage through aging stone and block walls. JLB answers it from the inside with interior drain tile, a sump pump, and sealed cracks that route groundwater away before it reaches the floor.
River-valley humidity creeps into crawlspaces and basements alike across Iowa Falls, feeding mold, musty air, and damp framing in the city's older homes. Rather than treating just one level, JLB spray-foams both the crawlspace and the basement together, sealing the whole underside against moisture for twice the protection at a lower cost than crews that encapsulate only one.
Properties stepping down from the Iowan Surface uplands toward the Iowa River shed runoff onto lower lots, where clay-heavy till drains slowly and pools against foundations. JLB grades these yards away from the house, lays French drains to intercept surface and ground water, and extends downspouts well past the walls to keep storm flow off basements near the bluffs.
Iowa Falls' oldest stone and concrete-block basements around the Metropolitan Opera House and Ellsworth Community College can bow or crumble once decades of freeze-thaw and saturated till finally overwhelm loosened mortar. When a wall is past saving, JLB rebuilds it in steel-reinforced poured concrete, with footings set safely below the regional frost line to resist future heaving.

The limestone bluffs that line the Iowa River gave Iowa Falls its "Scenic City" name, and that same river-cut valley is where Ellsworth Community College, the Metropolitan Opera House, and the older downtown homes all sit within a short walk of the water. JLB works this corner of Hardin County out of its Boone office, sending the same in-house crew to the river-terrace houses near downtown and the newer streets running out along U.S. Highway 20 and U.S. Highway 65. A college-and-agriculture town spread across bluff and bottomland means foundations of very different ages and types, and JLB diagnoses each one by where in Iowa Falls it actually stands.
What sits under most of Hardin County is Iowan Surface ground, not the younger till found nearer the capital, and the distinction matters for how a foundation moves here. This is older glacial material that weathered and eroded for thousands of years longer, leaving a clay-heavy cap that drinks in spring rain and snowmelt, swells, and then pulls back tight as it dries. A foundation riding on soil that keeps changing volume gets pushed unevenly — that is the origin of the stair-step cracks, pinched doorways, and slowly leaning basement walls that turn up in homes that looked fine a few seasons earlier. Add the long north-central Iowa winters working frost deep into that clay, and aging mortar joints in the town's stone and block basements give way well ahead of newer poured walls. JLB scopes each repair to land on firm ground beneath the restless surface layer instead of chasing the symptom.
JLB provides foundation repair and basement waterproofing throughout Iowa Falls and the rest of Hardin County — from the river-terrace neighborhoods along the Iowa River and the historic downtown to the newer homes spreading out along U.S. Highway 20 and U.S. Highway 65. Our crews understand how this Iowan Surface ground bears load and where the water collects.
Numbers That Speak for Themselves
A high water table near the Iowa River and the water-holding Iowan Surface soils across Hardin County both work against your foundation every wet season. If you've noticed cracks, water in the basement, or doors that stick in your Iowa Falls home, a free professional assessment finds the cause before it compounds.
Not Sure What You're Dealing With?
Hardin County sits on the Iowan Surface — older, weathered glacial till under clay. This ground holds water and shifts under load, so JLB scopes every repair to reach stable strata below the weathered layer instead of patching at the surface.
Homes on the lower terraces near the Iowa River sit close to a water table that pushes groundwater against basement walls year-round. JLB designs interior drainage and sump systems for the chronic moisture that defines Iowa Falls's riverside neighborhoods below the limestone bluffs.
From the pre-1940 stone basements around downtown and the Metropolitan Opera House to mid-century block and newer poured walls out toward US-20, JLB carries the equipment and training to repair every foundation type in the Scenic City's housing stock.
Our in-house crew handles foundation repair, waterproofing, and concrete across Iowa Falls and Hardin County, and every estimate is free with clear written pricing before any work begins.

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."

Most residential foundation and waterproofing jobs in Iowa Falls run from one to a few days on site once work begins, while larger structural stabilization or full interior drainage systems can take longer; flatwork pours add cure time before the surface carries weight. Scheduling starts with a free on-site assessment, after which JLB gives you a written scope and a target window. Since the crew travels from the Boone office to cover Iowa Falls and the rest of Hardin County, jobs in the area are grouped to keep timelines tight — call (515) 444-9234 to get on the calendar.
New construction is not immune. When a lot on the edge of Iowa Falls is freshly cut and graded, the fill placed back around and under the foundation has not had time to fully consolidate, so it keeps compressing under the weight of the house for the first few years. On the clay-rich Iowan Surface ground around Hardin County, that fill also swells and shrinks with each wet-and-dry cycle, which can leave a young home with hairline cracks, a settling slab, or a door that suddenly sticks. JLB evaluates whether the movement is normal early settling or something that needs piers or drainage to stop.
Yes. JLB's structural foundation repairs carry a warranty that transfers to the next owner, so the work done on your Iowa Falls home stays protected when the property changes hands. That matters in a market where buyers ask hard questions about a basement or foundation — being able to hand over documented, warranted repairs is a real selling point. The specific terms and coverage are spelled out in writing with your free estimate, so you know exactly what transfers before any work starts.
Our team schedules an on-site inspection that accounts for the river-valley water table, Hardin County's Iowan Surface soils, and your specific foundation type.
