Unanchored entrance stairs tilt forward as loose surface soil shifts beneath porch landings. In Rialto, where owner-occupied homes make up 63.5% of residential properties, exterior entries must handle daily foot traffic without pulling from the structure. When steps rest on grade, rainfall washes under the tread and creates hollow voids. Rafael Ocampo directs crews to anchor steel dowels into the existing concrete stem wall so the stair mass cannot drift forward.
The subgrade in this part of San Bernardino County contains coarse sandy deposits documented by the USDA Web Soil Survey. These soils allow quick drainage but settle unevenly when water runs off roof valleys without gutter diversion. Our team excavates a perimeter grade beam down 12 inches to reach firm ground before setting forms. We compact clean crushed rock into the trench, creating a rigid base that distributes the stair weight evenly across the footprint.
Every set of risers and treads follows strict rise and run geometry to prevent trip hazards. Operating under a CSLB C-8 license since 2016, our crew builds rigid forms using dimensional lumber braced against lateral hydraulic pressure. We pour 4,000 PSI concrete through the throats and risers in one continuous operation. Consolidating the wet mix with internal vibrators eliminates honeycombing, producing solid stone steps that remain level for decades.
