A concrete patio installation transforms your backyard into a functional outdoor living space. The process includes excavation, gravel base compaction, forming, optional wire mesh or rebar reinforcement, pouring concrete to a 3.5–4 inch thickness, and finishing with your choice of broom, smooth, or exposed-aggregate texture. Proper drainage slope (1/4 inch per foot) away from your home's foundation is critical in NorCal's rainy winters.

NorCal's expansive clay soils can shift seasonally — a well-compacted gravel base is essential to prevent slab movement.

Foster City is located in San Mateo County (Peninsula). Planned lagoon community built on reclaimed land with 1960s–80s homes and waterway views. The local utility provider is PG&E.
