Engineered Solutions for Inland Empire Soils
Benchmark Foundation Co was established to give San Bernardino County homeowners an honest, engineering-first alternative to temporary cosmetic patches. Based at 1030 E Holt Blvd in Ontario, our firm focuses on durable, mathematically sound foundation stabilization that stands up to expansive clay, hydrostatic pressure, and regional seismic hazards.
Uncompromising Quality & Code Compliance
We utilize only ICC-ES certified steel brackets, piers, and carbon fiber straps. Our work meets or exceeds California Title 24 seismic retrofitting guidelines and local Ontario municipal building codes.
Rooted in Ontario and the Greater Inland Empire
From older mid-century homes with unreinforced cripple walls to modern slab-on-grade tract developments experiencing settlement, we understand the distinct structural architecture of Western San Bernardino County.
