Concrete Foundations & Footings
Strong foundations and properly placed footings are the key to any structure that lasts.

Why Foundations Matter
Your foundation supports everything above it. Whether you are building a new home addition, a garage, or a room extension, the foundation needs to be rock solid. Poor foundation work causes cracks in walls, doors that stick, and floors that slope. Getting it right from the start saves you from expensive structural problems later.
We install concrete foundations in Redwood City that meet or exceed local building codes. Our work includes proper excavation, compacted base, correct reinforcement, and quality concrete. We understand California soil conditions and how to build foundations that stay stable even when the ground shifts slightly during seasonal changes.
Types of Foundations We Build
Different projects need different foundation types. A simple storage shed might only need concrete piers or a slab on grade. A room addition requires a full perimeter foundation that ties into your existing structure. A detached garage needs footings deep enough to support the walls and roof load. We design the foundation based on what you are building and the soil conditions on your property.
Foundation types we commonly install:
- Slab on grade foundations for single story structures
- Perimeter stem wall foundations for room additions
- Concrete footings for deck posts and support columns
- Grade beam foundations for hillside construction
- Pier and beam foundations for crawl space applications
- Garage and workshop foundations with proper drainage
The Foundation Construction Process
Foundation work starts with accurate layout and excavation to the correct depth. In California, frost is not usually a concern, but we do need to get below the organic topsoil and reach stable ground. Footings go deeper than foundation walls to spread the load and prevent settling. The width and depth depend on soil bearing capacity and the weight of the structure above.
After excavation, we build forms to contain the concrete and place rebar according to engineering specifications. The concrete pour must happen all at once to avoid cold joints that create weak spots. We make sure the foundation is level and has proper drainage away from the structure. This same attention to detail applies whether we are building retaining walls or complete foundations for new construction.
Working with Building Codes and Inspections
Foundation work requires permits and inspections to ensure it meets local building codes. We handle all the paperwork and coordinate with building inspectors. The inspector checks the excavation, rebar placement, and sometimes the concrete pour itself. Having experienced contractors who understand code requirements makes this process smooth.
Your foundation is permanent, so getting it right the first time is essential. We follow best practices for concrete mix design, placement, and curing. The result is a foundation that provides a solid base for your structure. For projects that also need quality concrete flatwork, we can handle the complete concrete package from foundation to finished floors.
