Foundation installation in Menlo Park CA - the right base for your lot and budget
Building new or adding on and not sure whether a slab or a raised foundation fits? We'll help you choose, then build it level.
Foundation installation in Menlo Park usually means one of two things. A slab is a single layer of reinforced concrete poured straight onto the ground. A raised foundation lifts your floor over a crawlspace and rests on concrete footings, the wide concrete base the walls stand on. Most people call us while they're planning a new home or an addition and want to know which type their lot and budget suit.
What goes wrong is usually underneath, ground that was raked level instead of dug out and packed, or water left running toward the house, so I look at the ground before anything else. Price and schedule both move with the foundation type, the ground and any survey or engineering the design needs. Menlo Park's Building Division issues permits for new buildings, additions and grading, and we don't set a date until we know what yours needs.
What our foundation installation work covers
- Slab or raised, explained first. Before I price anything, I walk you through a slab versus a raised foundation and what each one means for your budget, so you can choose with both in front of you.
- Footings and piers to the drawings. We dig and pour the footings and piers at the sizes and depths the drawings call for, because that's what the weight of the house actually rests on.
- Base dug out and drained. We dig out and pack the subgrade, the ground the foundation sits on, and shape the soil around it so rain runs away from the house.
- I estimate and run the job. I come out to write the estimate myself, our crew does the work, and I run the job on site. We've been in business since 2023, and we're licensed and fully insured.
What goes wrong under a foundation
| Problem | What it looks like | Usual fix |
|---|---|---|
| Base that settles | What it looks like: Cracks that widen, floors that slope, doors that start sticking | Usual fix: Dig out soft soil and pack a firm base |
| Water toward the house | What it looks like: Puddles against the wall and a damp crawlspace after rain | Usual fix: Grade the soil so water runs away |
| Forms out of square | What it looks like: Walls that don't line up and framing that needs shimming | Usual fix: Square and level the forms before the pour |
| Rushed pour in heat | What it looks like: A dusty, weak top that chips along the edges | Usual fix: Pour in cooler hours and let it cure |
Slab, raised or engineered foundation
- Slab. A slab suits a fairly flat lot, with the floor sitting on one layer of concrete and rebar, steel bars inside that hold it together.
- Raised foundation. A raised foundation suits a sloped lot or a house you want to reach underneath, with a wall around the edge on footings and concrete piers holding the floor framing inside.
- Piers and grade beams. Drilled piers tied together by grade beams, concrete beams that span between them, suit loose fill or steep ground, and an engineer designs them before we build.
How we plan and pour a foundation
- Call or send the form. Tell us the address and whether it's a new home or an addition, and we'll set a time for me to come out.
- I measure and look. I measure, check the ground, the trees nearby and where water runs, then write down in plain words what we'll build before I put a price on it.
- City review and permits. We learn what your city asks for. Menlo Park plans may pass more than one review, and we handle the paperwork or help you with it.
- Forms, then the pour. Our crew sets the forms and I check them before any concrete is ordered, then we pour and let it cure, the slow hardening that gives it strength.
- Walk-through. When it's done, I walk the finished foundation with you and our crew clears away the forms and the mess.
What keeps a new foundation sound
Most of what keeps a foundation sound is decided before the concrete shows up, in the packed base, the square forms and where the water goes. That's the part I won't trim to save money, because a neat finish on a foundation that settles buys you nothing.

Foundation questions we hear most
Is a slab or a raised foundation cheaper to build in Menlo Park?
A slab is usually easier on the upfront budget. One structural engineering firm says a post-tensioned slab, one with steel cables pulled tight after the pour, generally needs less labor and formwork than a deep raised foundation. Your lot may still point to a raised one, and that's what the site visit sorts out.
What does a slab foundation cost near Menlo Park?
An installed slab foundation in San Francisco usually costs about $7 to $18 per square foot, and that's the closest local figure we have. Where your job lands depends on its size, the soil, the base work and any engineering, so the estimate gives you a price for your own lot.
Do I need a survey or an engineer for a new foundation in Menlo Park?
For a new home, you'll generally need a boundary and topographic survey, and for an addition the city decides by project. An older national builders' guide says pilings, drilled piers and grade beams need a licensed design professional. Where your design calls for either, we plan for them from the start.
Who can legally build a house foundation in California?
Anyone contracting for work worth $1,000 or more in labor and materials combined must hold a current, valid license from the Contractors State License Board. A foundation job is well past that, so ask for the license and check it with the board before you sign.
What should I know about building a foundation on a Menlo Park lot?
Three things can change the plan before we pour. Work within the drip line of a heritage tree, the ground under its outer branches, needs an arborist report, and a lot in a state earthquake hazard zone needs geologic and engineering studies. Near the bay, lots generally sit on old fill that can settle and hold shallow groundwater.
