New foundation construction is the ground-up structural work that sets the base for a new home, addition, or building, and it is the work Benitez Concrete Construction does best. As a new foundation construction contractor serving San Jose and the greater Bay Area, we bring more than 30 years of structural concrete experience to every pour, from slab-on-grade and raised foundations to engineered pier and grade beam systems. When you are building new, the foundation is the one part of the project you cannot go back and fix easily, so it is worth getting right the first time.
What New Foundation Construction Involves
New foundation construction covers everything from the first excavation to the finished, inspected concrete your framer builds on. The right foundation type depends on the soil, the slope, the structure above, and the engineer’s design. A level lot with good soil may take a straightforward slab, while a hillside parcel or expansive clay often requires a pier and grade beam foundation engineered to reach stable ground.
Benitez builds the full range of new foundations: slab-on-grade, stem wall and raised foundations, structural grade beams, and deep pier systems. It is all part of the structural foundation construction that has been our focus for three decades, and it feeds directly into the residential and commercial concrete we pour across the South Bay.
When New Construction Calls for an Engineered Foundation
Every new build needs a foundation, but some sites need far more engineering than others. Plan for a purpose-built foundation when:
- You are building on a sloped, terraced, or hillside lot
- The soil is expansive clay, fill, or has a history of movement
- The design includes a basement or below-grade living space
- The structure is multi-story or carries heavy point loads
- The site sits in a seismic zone where the foundation must resist lateral force
If you are weighing foundation types for a new build, our post on what a concrete foundation costs in the Bay Area explains the factors that drive the design and the budget.
Why Bay Area Builders and Homeowners Choose Benitez
On a new build, the foundation sets the standard for everything above it, so experience and precision matter from the first pour. Benitez Concrete Construction has built new foundations across the Bay Area for more than 30 years as a family-owned company. We hold California Contractor License #706549, classification C-8 (Concrete), and we are fully bonded and insured.
We work alongside owners, general contractors, structural engineers, and architects, which keeps new construction on time and on budget through permitting and inspection. Our portfolio includes new foundation work on demanding projects in Los Altos Hills, Hillsborough, and other Peninsula towns where the soil and the standards leave no room for shortcuts. You can read more about our team and our approach to structural concrete.
Our New Foundation Construction Process
Every project is different, but a new foundation follows a clear, controlled sequence:
- Plans and engineering. We review the structural plans and soils report with your engineer and confirm the foundation design.
- Permitting and layout. We handle the permitting requirements and lay out the foundation to the plan.
- Excavation and grading. We excavate, grade, and compact the pad, and shore where the site requires it.
- Forming, rebar, and pour. We form the foundation, place reinforcement to spec, and pour the concrete to the engineered design.
- Inspection and handoff. We pass the required inspections and deliver a foundation ready for framing.
New Foundation Construction Across the Bay Area
Benitez pours new foundations in San Jose, Atherton, Cupertino, Hillsborough, Los Altos Hills, Los Gatos, Menlo Park, Mountain View, Palo Alto, and Redwood City. New construction on established lots often ties into related structural work: underpinning where a new addition meets an older foundation, and foundation and seismic retrofit when a project brings an existing structure up to current standards at the same time.
Frequently Asked Questions
What type of foundation is best for a new home?
The best foundation for a new home depends on the soil, the slope, and the design. Level lots with stable soil often use a slab-on-grade or stem wall foundation, while sloped, hillside, or expansive-soil lots usually need an engineered pier and grade beam foundation. A soils report and structural plans determine the right system for your site.
Do you build foundations for both custom homes and additions?
Yes. We pour new foundations for custom homes, additions, ADUs, and commercial buildings. For additions, we also handle the structural connection between the new foundation and the existing one so the two work together. We build to the engineer’s design in every case.
Can you build a new foundation with a basement?
Yes. Below-grade living space is one of our specialties. A new basement foundation involves deeper excavation, shoring, and waterproofing along with the structural concrete, and we coordinate the full sequence with your engineer and builder to keep the site safe and on schedule.
How long does new foundation construction take?
Every project is different. The timeline depends on the foundation type, the soil, site access, weather, and permitting. After we review your plans and the site, we give you a realistic schedule. A site visit is the only way to estimate your project accurately.
Do you work with our general contractor and engineer?
Yes. We regularly partner with general contractors, structural engineers, and architects, and we can work within your existing team. Our role is the concrete and structural execution, built to the engineer’s specifications and inspected to code.
