The Inland Empire spans San Bernardino and Riverside Counties and covers a wide range of terrain, from the valley floor cities of Ontario, Fontana, and Riverside to the foothill communities of Rancho Cucamonga and Upland. The region's dominant soil challenge is expansive clay, specifically Bonsall and Arlington series soils, which swell in winter and shrink in the dry months from May through November. That cyclical movement is the leading cause of cracked driveways, buckled slabs, and tilted retaining walls across the IE. Summers regularly push past 95 to 100 degrees, and the dry Inland Empire air causes concrete to cure faster than in coastal markets.

Expansive clay soils cover most of the Inland Empire valley floor, including the Arlington clay series near Riverside and Ontario lowlands and the Bonsall series in pockets across the region. These soils swell when winter rains arrive and shrink back during the long dry season, putting stress on slabs from below. Concrete poured without a properly compacted gravel base and well-placed control joints will crack faster here than in areas with sandy or loam subgrade.
Inland Empire summers regularly reach 95 to 100 degrees, and the dry air causes concrete to cure faster than in coastal Southern California. Concrete that is not kept moist during the first week after pouring develops surface shrinkage cracks that allow water entry in winter. That seasonal cycle of wet winters and dry summers then causes the clay subgrade to expand and contract again, compounding the damage on slabs that were not cured correctly from the start.
We serve residential and commercial properties across the Inland Empire, from concrete driveway replacements on single-family lots in Fontana and Ontario to concrete foundations and concrete slabs for commercial projects. Our concrete work in this region accounts for the local soil behavior and heat conditions on every job, from subbase preparation through the curing process.
At a glance
Concrete driveway installation and concrete slab work are in constant demand across the Inland Empire, where clay soil movement and decades of heat cycles break down original flatwork on residential and commercial properties alike. Concrete foundations and foundation additions are critical in this region because the shrink-swell behavior of Bonsall and Arlington clay series soils puts ongoing stress on any slab poured without proper subgrade preparation. Concrete curbs, concrete pads, and sheds and equipment pads are also common requests on the larger lots found throughout IE cities.

Common questions from Inland Empire, CA customers about our services, process, and coverage.
The Inland Empire sits on expansive clay soils that swell when wet and shrink during the dry season, putting pressure on slabs from below. Combined with summer temperatures that regularly exceed 95 degrees and cause rapid surface drying during curing, concrete here faces more stress than in coastal markets. Proper subbase preparation, correct reinforcement, and well-placed control joints are what separate flatwork that lasts from flatwork that fails within a few years.
Yes. We install concrete driveways, patios, slabs, foundations, curbs, ramps, and retaining walls for both residential and commercial properties throughout the Inland Empire. Commercial projects often involve concrete pads, equipment pads, and concrete curbs in addition to flatwork.
Spring and fall are generally the most favorable seasons for concrete work in the Inland Empire because temperatures are moderate and the risk of rapid surface drying is lower than in summer. Summer pours are possible but require careful curing practices to prevent shrinkage cracks from forming in the first week after the pour.
Yes. Concrete foundations and foundation additions for room additions, detached garages, and ADUs are part of our scope across the Inland Empire. Foundation work in this region requires proper subgrade preparation and reinforcement that accounts for the clay soils that shift seasonally throughout the area.
