Foundation, Waterproofing & Concrete Across Polk County, Iowa

From the county seat of Des Moines out to the smaller communities of Elkhart, Alleman, and Berwick, Polk County homeowners deal with the same expansive Iowa till that cracks walls, floods basements, and heaves slabs. JLB provides foundation repair that stabilizes settling structures, basement waterproofing that keeps water out for good, and concrete services that restore driveways, patios, and walkways. Whether you are in downtown Des Moines or a quiet acreage near Alleman or Berwick, our crews know how local soil behaves and how to fix the damage it causes.

Foundation & Waterproofing

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

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

Steel push pier foundation stabilization in Polk County, Iowa

Foundation Repair in Polk County

Foundation settlement is a recurring problem across Polk County because the Des Moines Lobe clay beneath most homes shifts with each wet and dry cycle. JLB stabilizes sinking and cracking foundations with steel push piers and helical piers driven to stable load-bearing soil, then lifts the structure back toward level where possible. We inspect homes throughout Des Moines and out to Elkhart, Alleman, and Berwick, matching the repair to the foundation type and the way the local soil has moved it.

  • 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 Polk County, Iowa

Basement Waterproofing in Polk County

Basement waterproofing is essential in Polk County, where heavy spring rains and snowmelt saturate the clay and force water against and under foundation walls. JLB installs interior drain-tile systems, sump pumps with battery backup, and wall vapor barriers to capture water and route it safely away from the home. The result is a dry, usable basement that holds up to the wet-dry swings that define Iowa's central counties.

  • 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 Polk County, Iowa

Crawlspace Encapsulation in Polk County

Crawlspaces under Polk County homes trap the moisture that rises out of damp clay soil, leading to mold, wood rot, and sagging floors above. JLB sets itself apart by spray foaming both the crawlspace and the basement for twice the protection at a lower cost than competitors who only treat one space. We seal the area with a heavy-duty vapor barrier, address standing water, and create a clean, dry, energy-efficient zone under your home.

  • 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 Polk County, Iowa

French Drains & Drainage in Polk County

Poor drainage is one of the biggest threats to foundations in Polk County, where dense till sheds water slowly and lets it pool against the house. JLB installs French drains, extends downspouts, and corrects grading to move surface and subsurface water away from the foundation before it can cause settlement or seepage. These drainage upgrades protect homes in Des Moines, Elkhart, Alleman, and Berwick from the runoff that follows every major Iowa storm.

  • 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 Polk County, Iowa

Foundation Wall Replacement in Polk County

When a Polk County foundation wall has bowed, cracked, or deteriorated beyond what reinforcement can fix, JLB performs full foundation wall replacement to restore the home's structural integrity. Decades of clay pressure and freeze-thaw cycles can push older block and poured walls past the point of repair. Our crews remove the failing wall, rebuild it to code, and pair it with proper waterproofing and drainage so the new wall is protected against the same forces that took down the old one.

  • 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
