Foundation, Waterproofing & Concrete Across Marshall County, Iowa

From the county seat of Marshalltown out to the smaller communities of Le Grand, Gilman, Laurel, Haverhill, and Clemons, Marshall County's mix of river-valley ground and aging farm-town housing puts real stress on a structure over time. We bring foundation repair, basement waterproofing, and concrete services to every one of those towns, treating a settling century home in Marshalltown the same way we treat a leaking block basement in Le Grand or a heaving driveway in Gilman, Laurel, Haverhill, or Clemons. One local crew, one straight estimate, no matter where in the county you are.

Foundation & Waterproofing

Foundation Repair, Basement Waterproofing & Crawlspace Services in Marshall County, Iowa

One local crew handles the whole structural side in Marshall County — piering, waterproofing, crawlspace encapsulation, drainage, and wall replacement. Here's how we fix each:

Steel push pier foundation stabilization in Marshall County, Iowa

Foundation Repair in Marshall County

Foundation repair across Marshall County means dealing with seasonal clay that swells in wet springs and shrinks through dry summers, working century-old foundations near Marshalltown's older neighborhoods and newer poured walls in places like Le Grand alike. We diagnose the actual cause of stair-step cracks, sticking doors, and sloping floors, then stabilize with steel push or helical piers driven to load-bearing strata so the movement stops for good.

  • Steel push piers and helical piers driven to stable load-bearing soil
  • Wall anchors and carbon-fiber straps for bowing or cracked walls
  • Engineered, permanent fixes — not surface patches
  • Transferable warranty and a free, no-pressure inspection

Interior drain tile and sump basement waterproofing in Marshall County, Iowa

Basement Waterproofing in Marshall County

Basement waterproofing here has to answer the Iowa River valley and the slow-draining Iowan Surface clay that traps water against your walls. We install interior drain tile, reliable sump systems with battery backup, vapor barriers, and exterior sealing to intercept water before it reaches the slab, keeping Marshalltown and Gilman basements dry through snowmelt and the heaviest spring storms.

  • Interior drain tile and sump systems sized for Iowa’s water table
  • Crack injection and wall-to-floor joint sealing
  • Vapor barriers and dehumidification to stop musty air and mold
  • Keeps the lower level permanently dry, backed in writing

Crawlspace encapsulation with vapor-barrier liner in Marshall County, Iowa

Crawlspace Encapsulation in Marshall County

Crawlspace encapsulation protects the many smaller and older homes in towns like Laurel, Haverhill, and Clemons, where vented crawls pull in humidity from damp county soil and breed mold, rot, and musty air upstairs. We seal the space with heavy liner, spray foam, and dehumidification — and JLB foams both the crawlspace and the basement for twice the protection at a lower cost than crews that treat only one.

  • Spray-foams BOTH the crawlspace AND the basement — twice the protection
  • Sealed vapor-barrier liner over floor and walls
  • Cuts humidity, mold, and energy loss from the stack effect
  • Done for less than competitors who seal only one or the other

French drain trench with gravel and drain pipe in Marshall County, Iowa

French Drains & Drainage in Marshall County

French drains and exterior drainage matter on Marshall County's flat farm ground and gentle river-valley grades, where water pools against foundations instead of running off. We design buried gravel drains, regrade problem yards, extend downspouts, and route runoff well away from the house so the clay around your footings stops staying saturated season after season.

  • French drains, regrading, and buried downspout extensions
  • Redirects surface and groundwater away from the foundation
  • Relieves the hydrostatic pressure that cracks walls and floors
  • Built for Iowa freeze-thaw and heavy spring snowmelt

Steel-reinforced foundation wall replacement in Marshall County, Iowa

Foundation Wall Replacement in Marshall County

Foundation wall replacement is the right call when a Marshalltown-area block or limestone wall has bowed, cracked through, or crumbled past what anchors and braces can hold. We shore the structure, remove the failed section, and rebuild with engineered poured or block walls and proper waterproofing, restoring full load capacity instead of patching a wall that will keep failing.

  • Full removal and rebuild of failed or severely bowed walls
  • Steel-reinforced poured concrete below the 42-inch frost line
  • Exterior waterproofing and proper drainage built back in
  • The permanent answer when bracing is no longer enough

Broom-finished concrete driveway for Marshall County, Iowa homes

Concrete Driveways in Marshall County

New and replacement concrete driveways in Marshall County are poured on a properly compacted base with control joints sized for Iowa's freeze-thaw swings, so a Marshalltown or Gilman driveway resists the cracking and frost heave that ruin slabs set on poor subgrade. We grade for drainage so meltwater runs off instead of pooling and lifting the surface.

  • Air-entrained mixes (5-7%) built to survive 100-120 freeze-thaw cycles a winter
  • Proper subgrade preparation over Des Moines Lobe glacial till
  • JLB's own in-house crew — no subcontractors
  • Free inspection plus the JLB transferable warranty

Concrete Patios & Outdoor Spaces in Marshall County

  • Site-specific subgrade prep for Des Moines Lobe glacial till
  • Proper joint placement and air entrainment to survive Iowa freeze-thaw

Stained & Colored Concrete in Marshall County

Stained concrete upgrades garage floors, patios, and interior slabs around Marshalltown with rich, permanent color worked into the surface rather than coated on top.

  • Permanent color that won't peel or fade
  • Integral color carried through the full slab depth
  • Proper curing for Iowa conditions
  • Works on patios, driveways, pool decks, and commercial floors

Concrete retaining wall with weep holes for Marshall County, Iowa homes

Concrete Retaining Walls in Marshall County

Concrete retaining walls hold back grade on Marshall County's river-valley slopes and uneven farm lots, preventing erosion and protecting foundations from soil and water pressure. We engineer walls with proper footings, drainage behind the wall, and reinforcement so they stand up to saturated clay and freeze-thaw loading.

  • Footings set below Iowa's 42-inch frost line
  • Rebar-reinforced for structural strength
  • Full drainage systems — weep holes, gravel backfill, and drain tile — to manage persistent hydrostatic pressure from the till
  • JLB's own in-house crew

Backyard fiberglass pool for Marshall County, Iowa homes

Pool Installation in Marshall County

Pool installation in Marshall County covers the concrete side of the project — excavation support, structural slabs, surrounding decks, and drainage — built on stable, compacted ground. We coordinate the concrete work so the pool shell and deck sit level and drain correctly, accounting for the area's clay soils and frost depth.

  • Authorized Iowa dealer for Kisol, Elegance by Kisol, and Exclusive Pools — three factory-built shell lines
  • Every shell carries a 15-year structural warranty (manufacturer's, travels with the product)
  • Dig to swim in 4-8 weeks on most installs
  • Excavation dug dead-level to manufacturer spec, with backfill placed in controlled lifts and compacted to proctor standards so it won't settle, crack the deck, or heave in Iowa's expansive till
