Urbandale Concrete Patios Built on a Compacted Base for Iowa Soil
Our process starts with the ground long before any concrete shows up. We strip the area, compact the subgrade, and grade a free-draining base, because a slab is only ever as flat as what sits beneath it. That groundwork is what carries Des Moines' 33 psf design snow load through winter and keeps the patio from dropping over a soft spot the next spring. Only once the base reads right do we set forms and pour.
Urbandale's established blocks come with mature landscaping that works on the soil. The big trees that make these 1960s-through-1990s neighborhoods handsome also pull moisture out of the ground in dry stretches, shrinking the soil around a slab. We account for that when we prep the base and lay out joints, so the patio holds its line as the ground swells and shrinks through the seasons.
Patio Finishes JLB Pours in Urbandale
Broom, stamped, colored, or exposed-aggregate — patio finishes that fit how you use the space.
Base prep that does the quiet work
The base is where a patio is won or lost.
A compacted, free-draining sub-base spreads the slab's weight evenly and bridges the seasonal movement of moisture-hungry soil. On the established lots off the Merle Hay Road corridor, where decades-old trees have reshaped the ground, that prep is the difference between a slab that stays put and one that cracks within a few seasons.
Forming and thickness set to the use
Thickness follows what the patio will hold.
A standard backyard slab gets four inches of air-entrained concrete over the prepared base, stepped up where it carries an outdoor kitchen, hot tub, or heavy furniture. We form to the layout you want and pour the 5 to 7 percent air range so freezing water expands into the mix rather than the surface.
Keeping the patio low-maintenance for years
A poured slab asks little once it's in.
There are no paver joints to weed or re-level and no units to heave out of line, so seasonal upkeep is mostly a rinse and the occasional sealer coat. We saw-cut control joints up front to steer cracking into clean lines, which keeps the surface reading intentional rather than worn. One JLB crew runs the whole job, and the patio can be poured as a pool deck under one contract.

What Makes Urbandale Concrete Different?
Central Iowa concrete endures 100 to 120 freeze-thaw cycles in a single winter. Each cycle expands trapped moisture and opens micro-fractures, which is why air-entrained mixes and correct joint placement matter far more here than in milder climates.

Signs You Need Patios in Urbandale
Cracks Across the Slab
Wandering cracks mean missing joints or a base that moved under the patio.
Uneven or Settled Sections
A patio that has dropped on one side was poured over loose or uncompacted fill.
Water Pooling on the Surface
Puddles after rain mean the slab lost its pitch and needs regrading.
Scaling or Pitting
A flaking, pockmarked surface is freeze-thaw damage working through the slab.
Heaving Against the House
A patio lifting toward the foundation can push water and ice where you don't want it.
Outgrown the Space
An undersized slab limits how you use the yard — a good time to rebuild bigger.

Concrete Patios & Outdoor Spaces in Urbandale — FAQ
A slab is only as flat as the ground under it. JLB strips, compacts, and grades a free-draining base so the patio carries its load evenly and doesn't drop over a soft spot, which is especially important on Urbandale's established, tree-shaped lots.
Large trees pull moisture from the soil during dry spells, shrinking the ground around a slab. JLB accounts for that movement in the base prep and joint layout so an Urbandale patio holds its line through the seasons.
A standard backyard patio is four inches of air-entrained concrete over a prepared base. JLB steps up the thickness wherever the slab carries an outdoor kitchen, hot tub, or other heavy load.
Very little. A poured slab has no paver joints to weed or re-level, so upkeep is mostly a rinse and an occasional sealer coat. Saw-cut control joints placed up front keep any cracking in clean, intentional lines.
Yes. Because the same in-house crew installs pools and pours concrete, the patio can go in as the surround for a new pool under one contract instead of two separate projects.
