Clay subgrades in Yorba Linda expand when wet and contract during dry heat, which cracks poorly prepared flatwork. Every long lasting installation begins with proper ground stabilization.
According to data from the USDA Web Soil Survey, much of northern Orange County contains clay loam soils with high shrink swell potential. When moisture infiltrates unprotected native dirt beneath a slab, the soil lifts the edges. As the subgrade dries during hot summer stretches, the ground shrinks away, leaving voids that cause unreinforced concrete to snap under vehicle weight.
In a community of 68,229 residents, property owners invest for durability rather than short term cosmetic patches. We excavate native soil beneath every project, install four inches of crushed aggregate, and mechanically compact the base. Rebar grids tied across the field and saw cuts spaced every ten feet prevent irregular cracks, keeping driveways and patios structural under vehicle and foot traffic.
