JLB's Concrete Services

Concrete Services in Knoxville, Iowa

JLB's concrete crew works throughout Knoxville, handling everything from residential driveways and patios to commercial flatwork and fiberglass pool installation. Every slab is built for central-Iowa freeze-thaw — air-entrained, properly jointed, and poured on a compacted base.

Concrete Services

Concrete Services in Knoxville, Iowa

JLB brings its full concrete crew to Knoxville — flatwork, decorative finishes, structural walls, and pools, all in-house. Here's what we pour locally:

Broom-finished concrete driveway for Knoxville, Iowa homes

Concrete Driveways in Knoxville

On Knoxville's rolling lots south of Lake Red Rock, JLB starts a driveway by cutting and compacting the subgrade to hold a level slab on terrain that wants to shed runoff downhill. The mix carries 5-7% air entrainment so the surface rides out the 100-120 freeze-thaw cycles a Marion County winter throws at it. One in-house crew runs subgrade prep through final broom finish.

  • 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 Knoxville, Iowa homes

Concrete Patios & Outdoor Spaces in Knoxville

A patio in Knoxville has to sit on ground that slopes. JLB grades and preps the subgrade across the clay-rich soils common in the southern metro, where the Des Moines Lobe thins into older Pre-Illinoian till and loess, then pours your choice of broom, stamped, colored, or exposed-aggregate finish. Joint placement and air entrainment are dialed for Iowa winters, and the patio can be poured under the same contract as a JLB pool.

  • 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 Knoxville, Iowa homes

Concrete Sidewalks & Walkways in Knoxville

Knoxville's seasonal runoff heading toward Lake Red Rock makes frost heave a real threat to walkways, so JLB builds sidewalks on a drained, compacted base with the correct concrete strength and 5-7% air entrainment. We handle plain residential replacements through ADA-capable commercial runs and decorative finishes. The clay-rich southern soils move, and the walkway is built to move with them.

  • 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 Knoxville, Iowa homes

Stamped Concrete in Knoxville

Stamped concrete gives a Knoxville home the look of brick, slate, stone, or wood without the upkeep of natural stone. JLB carries integral color and surface hardeners through a slab built over a drained base, which matters on the rolling, clay-heavy ground that runs through Marion County toward Lake Red Rock. The finish is engineered to hold through Iowa freeze-thaw, not 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 Knoxville, Iowa homes

Concrete Pool Decks in Knoxville

Because JLB sets pools and pours decks with the same crew, a Knoxville backyard gets one contract instead of two contractors arguing over grade. Pool decks go down with air-entrained concrete and correctly spaced expansion joints so soil movement on these rolling southern lots doesn't crack or tilt the slab. The surface is finished slip-resistant for wet feet and reinforced to stay level.

  • 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 Knoxville, Iowa homes

Stained & Colored Concrete in Knoxville

For Knoxville patios, driveways, and shop floors, JLB uses acid stains, water-based stains, and integral color that runs the full depth of the slab so it never peels or fades. Integral color is the safer choice on exterior slabs facing Marion County's heavy freeze-thaw load. We cure the concrete properly for Iowa conditions so the color stays true season after season.

  • 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 Knoxville, Iowa homes

Concrete Retaining Walls in Knoxville

Knoxville's rolling hills and runoff toward Lake Red Rock make retaining walls as much about water as about grade. JLB sets footings below Iowa's 42-inch frost line, reinforces the wall with rebar, and builds in weep holes, gravel backfill, and drain tile to relieve the hydrostatic pressure that builds in the slow-draining southern-transition soils. The result holds the hillside and the water both.

  • 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 Knoxville, Iowa homes

Pool Installation in Knoxville

JLB is an authorized Iowa dealer for Kisol, Elegance by Kisol, and Exclusive Pools, and installs the full fiberglass package in a Knoxville backyard — excavation, shell, plumbing, backfill, and deck — with no subcontractors. Fiberglass flexes with the clay-rich ground south of Lake Red Rock where a gunite shell would crack, and each shell carries a 15-year structural warranty. Most installs run dig-to-swim in 4 to 8 weeks.

  • 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 Knoxville, Iowa homes

Concrete Parking Lots in Knoxville

Commercial lots serving Knoxville's downtown core and the traffic around Knoxville Raceway need concrete that takes a beating. JLB specs heavy-duty 4,000-5,000+ PSI mixes over a subgrade prepped for the clay-rich southern soils, with air entrainment for freeze-thaw and drainage routed to manage Marion County's runoff. We build, expand, and replace lots that hold up to weather and load.

  • 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 Knoxville, Iowa homes

Warehouse & Industrial Floors in Knoxville

For warehouse and industrial floors near Knoxville and the wider I-35/I-80 corridor, JLB pours 6-12 inches at 4,000-5,000+ PSI with joint spacing set for forklift and heavy traffic. Subgrade prep accounts for the older till and loess of the southern metro so the slab stays flat under load. The full sequence — prep through finish — is handled by one in-house crew built for Iowa frost.

  • 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 Knoxville, Iowa homes

ADA Ramps & Compliance in Knoxville

ADA ramps for Knoxville's commercial, municipal, and institutional buildings have to keep their slope and landings code-compliant for years, which is why JLB sets footings below the 42-inch frost line. Air-entrained, reinforced concrete holds the precise 1:12 slope through Marion County's freeze-thaw and the soil movement that comes with this rolling southern ground. Every ramp meets federal ADA requirements plus local code.

  • 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 Knoxville Homeowners

Yes. JLB's own concrete crew works throughout Knoxville 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.
