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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

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.
