Johnston Concrete Patios Graded for High Groundwater and Iowa Snow
A poured patio and a paver patio solve the same problem in opposite ways. Pavers shift at the joints, weed up, and need periodic re-leveling; a properly poured slab gives you one continuous, stable surface that carries Des Moines' 33 psf design snow load and clears with a single shovel pass. On the large custom-home lots common across Johnston, that low-fuss, monolithic surface is usually what homeowners are after, and we pour it over a compacted base to keep it flat for the long haul.
Johnston's wooded hills near Saylorville Lake sit on a high water table. Proximity to the lake pushes seasonal groundwater up, and the lower-lying developments here feel real hydrostatic pressure. A patio in this terrain has to move water decisively, so we read the lot's drainage before forming and pitch the slab to keep runoff off the foundation. Around the custom-home hills near Terra Park, that grade protects the basement below as much as the slab on top.

Patio Finishes JLB Pours in Johnston
Broom, stamped, colored, or exposed-aggregate — patio finishes that fit how you use the space.
Why poured concrete fits these lots
One slab beats dozens of units for upkeep.
A poured patio has no joints to weed, no pavers to heave out of line, and a surface a snow blower glides across. For the larger Johnston backyards built since the 1980s, that means a finished look with minimal seasonal work.
Load and reinforcement for custom features
Reinforcement matches what the slab carries.
A standard patio gets four inches of concrete over a prepared base, stepped up and tied with steel where it holds an outdoor kitchen, fire feature, or hot tub. We set the slab to what you'll actually put on it so the edges carry the weight without cracking.
Drainage that protects the basement
The slope is the foundation's first defense.
With Saylorville's high water table working against lower lots, we pitch the patio a deliberate fall so rain and snowmelt run clear of the house rather than ponding against the wall. The slab also carries 5 to 7 percent entrained air, so freeze-thaw doesn't scale it. One JLB crew runs the whole project, and the patio can be poured as a pool surround under one contract — a natural pairing on Johnston's big lots.

Concrete Patios & Outdoor Spaces in Johnston — FAQ
A poured slab gives one continuous surface with no joints to weed, no units to heave, and easy snow clearing, while pavers shift and need periodic re-leveling. On Johnston's large custom-home lots, the low-maintenance poured surface is usually the better fit.
Proximity to Saylorville Lake pushes seasonal groundwater up, so JLB reads the lot's drainage first and pitches the slab to carry runoff clear of the house. On lower-lying Johnston lots, that grade protects the basement as much as the patio.
Yes. JLB steps up the slab thickness and ties in steel reinforcement under any outdoor kitchen, fire feature, or hot tub, so the edges hold the load without cracking.
The slab carries 5 to 7 percent entrained air, the ACI recommendation, so freezing water expands into the mix instead of scaling the surface. Combined with a compacted base, that keeps a Johnston patio sound through repeated freeze-thaw.
Yes. The same in-house crew installs pools and pours concrete, so the patio can be built as the surround for a new pool under one contract — a natural pairing on Johnston's larger lots.
