Broom-finished concrete driveway for Marshalltown, Iowa homes

Concrete Driveways in Marshalltown

JLB pours residential and commercial driveways across Marshalltown on a subgrade prepped over the Des Moines Lobe glacial till, with an air-entrained mix in the 5-7% range so the slab can take 100-120 freeze-thaw cycles a winter without spalling. In the older central neighborhoods near the Tremont Water Tower, where 1940s-60s lots sit on saturated river-valley ground, that drainage-conscious base prep is what keeps a new drive from heaving.

  • 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

Warm ashlar stamped concrete patio for Marshalltown, Iowa homes

Concrete Patios & Outdoor Spaces in Marshalltown

Because Marshalltown sits low along the Iowa River, a patio here lives or dies on what goes under it, so JLB excavates and preps the subgrade over the local till before a single yard is poured. One in-house crew runs the job from dig to broom-finish, stamped, colored, or exposed-aggregate finish, and if you want the patio tied into a pool, the same crew handles both under one contract.

  • Site-specific subgrade prep for Des Moines Lobe glacial till
  • Proper joint placement and air entrainment to survive Iowa freeze-thaw
  • One in-house crew handles excavation through finish
  • Can be paired with a JLB pool installation under a single crew

Broom-finished concrete front walkway for Marshalltown, Iowa homes

Concrete Sidewalks & Walkways in Marshalltown

Frost heave is the enemy of any walkway in Marshall County, and JLB builds sidewalks to ride out the till movement that buckles slabs in Marshalltown's flat floodplain blocks. Whether it's a plain replacement on a 1950s lot or an ADA-capable run for a commercial site, the concrete is poured to the right strength with 5-7% air entrainment so the surface stays flat through the thaw.

  • Built to handle expansive till movement and frost heave
  • Correct concrete strength and 5-7% air entrainment
  • Full range from plain replacement to decorative finishes
  • JLB's own in-house crew

Italian slate stamped concrete for Marshalltown, Iowa homes

Stamped Concrete in Marshalltown

JLB lays stamped concrete in Marshalltown in patterns that read as brick, slate, stone, or wood, using integral color and surface hardeners that survive the freeze-thaw battering this part of central Iowa takes. The base and drainage get engineered for the river-valley till under the historic core, so a stamped drive or patio holds its pattern past the first winter rather than just the first summer.

  • Integral color and surface hardeners engineered for Iowa freeze-thaw
  • Proper base and drainage over glacial till
  • Durable, low-maintenance alternative to natural stone
  • JLB's own in-house crew

Concrete pool deck at the water edge for Marshalltown, Iowa homes

Concrete Pool Decks in Marshalltown

A pool deck in Marshalltown has to handle real soil movement on this saturated Iowa River ground, so JLB pours with an air-entrained mix and sets the expansion joints to let the slab move without cracking. Since JLB installs the pool too, one crew can set the shell and pour the slip-resistant deck around it on a single contract, no coordinating between trades.

  • Air-entrained mixes and correct expansion joints for Iowa soil movement and freeze-thaw
  • JLB can set the pool AND pour the deck — one crew, one contract
  • Proper reinforcement for a deck that stays level
  • Free inspection

Stained decorative concrete patio for Marshalltown, Iowa homes

Stained & Colored Concrete in Marshalltown

JLB stains and colors concrete throughout Marshalltown using acid staining, water-based stains, and integral color carried through the full slab depth so it can't peel or flake off. On patios, drives, pool decks, and commercial floors alike, the slab is cured for Iowa conditions, which matters on the temperature swings that drive the 100-120 freeze-thaw cycles this town sees each winter.

  • 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 Marshalltown, Iowa homes

Concrete Retaining Walls in Marshalltown

Every JLB retaining wall in Marshalltown is footed below Iowa's 42-inch frost line and rebar-reinforced so it stays put on the gentle uplands and floodplain edges along the Iowa River. Each wall gets weep holes, gravel backfill, and drain tile to bleed off the persistent hydrostatic pressure that builds in this poorly-draining valley till, the same pressure that stair-steps the old block foundations in town.

  • 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 Marshalltown, Iowa homes

Pool Installation in Marshalltown

JLB installs fiberglass pools in Marshalltown start to finish in-house, as an authorized Iowa dealer for Kisol, Elegance by Kisol, and Exclusive Pools, with most digs going from excavation to swim in 4-8 weeks. On the saturated ground near the river the excavation is dug dead-level to spec and the backfill compacted in lifts, and a fiberglass shell flexes with soil movement where gunite would crack; every shell carries a 15-year structural warranty.

  • 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

Concrete parking lot with control joints for Marshalltown, Iowa homes

Concrete Parking Lots in Marshalltown

For commercial sites around Marshalltown, from lots serving the historic core to facilities near the Iowa Veterans Home, JLB builds parking lots in heavy-duty 4,000-5,000+ PSI concrete over a subgrade prepped for the local glacial till. Drainage is engineered for the heavy rainfall this river town gets, and the mix is air-entrained to take the freeze-thaw load Marshall County winters throw at pavement.

  • Heavy-duty 4,000-5,000+ PSI specifications
  • Proper subgrade preparation over glacial till
  • Air entrainment for Iowa freeze-thaw
  • Drainage engineered for Iowa precipitation and frost

Sealed warehouse concrete floor for Marshalltown, Iowa homes

Warehouse & Industrial Floors in Marshalltown

JLB pours warehouse and industrial floors in the Marshalltown area at 6-12 inches and 4,000-5,000+ PSI, with joint spacing set for forklift and heavy traffic. The subgrade is prepped for the Des Moines Lobe till that runs under this stretch of central Iowa, and JLB runs the full sequence in-house so a distribution or manufacturing floor here holds flat through the deep frost the region reaches.

  • 6-12" thickness at 4,000-5,000+ PSI
  • Proper joint spacing for forklift and heavy traffic
  • Subgrade preparation for glacial till
  • Built for Iowa frost and freeze-thaw

Concrete ADA ramp with handrail for Marshalltown, Iowa homes

ADA Ramps & Compliance in Marshalltown

JLB builds ADA-compliant concrete ramps for Marshalltown's commercial, municipal, and institutional sites, holding precise 1:12 slope and code-compliant landings on facilities like the Iowa Veterans Home. The footings go below the 42-inch frost line and the reinforced, air-entrained concrete keeps the ramp meeting federal and local code even as Marshall County ground shifts through repeated freeze and thaw.

  • Precise 1:12 slope and code-compliant landings
  • Air-entrained, reinforced concrete that holds compliance through Iowa freeze-thaw and soil movement
  • Deep footings below the 42-inch frost line
  • Meets federal ADA requirements plus local code

Concrete Questions for Marshalltown Homeowners

Yes. JLB's own concrete crew works throughout Marshalltown and the surrounding Des Moines metro — driveways, patios, sidewalks, stamped and stained concrete, pool decks, retaining walls, and more. Every job is handled in-house from subgrade prep through the final finish. Call (515) 717-8560 for a free estimate.

Central Iowa runs roughly 100-120 freeze-thaw cycles a winter on the Des Moines Lobe. JLB uses 5-7% air-entrained mixes, places control joints correctly, compacts the subgrade, and sets structural footings below the 42-inch frost line so flatwork resists scaling, cracking, and heave.

In-house. The same JLB crew handles excavation, forming, reinforcement, the pour, and the finish — no subcontractor handoffs. On pool projects, that same crew sets the fiberglass shell and pours the surrounding deck under a single contract.
