San Bernardino sits directly below the steep slopes of the San Bernardino Mountains, catching runoff that deposits loose sand and cobble across residential parcels. When summer temperatures climb past 100 degrees, surface water evaporates faster than the lower mass can hydrate, creating internal stress that fractures unreinforced slabs. San Bernardino Concrete Pro places every driveway over a compacted base of crushed rock to bridge these loose alluvial pockets.
Reuben Castillo spent 19 years working concrete crews before founding the business in 2017, setting driveway specifications to match the local ground conditions. We saw control joints across the slab at intervals no greater than 10 feet during our warm seasons to govern shrinkage stress as the mix sets. The pour uses a 4,000 pound per square inch mix designed according to standards published by the Portland Cement Association.
Our crews work under CSLB C-8 licensing and carry liability insurance on every job across the Inland Empire. Each driveway includes a written workmanship guarantee against defects in how it was built, confirming the depth and base preparation match the signed contract. Subgrade settlement from drying will not undermine the structural slab when the base is compacted to 95 percent relative density.
