Concrete Foundations and Slabs in Salinas, CA

Foundations and Slabs · Salinas, CA

Slabs and footings poured to the engineer's plans

A concrete slab carries everything built on top of it, so the part you never see matters most. Aguilar and Sons Construction pours new slabs and footings in Salinas and across the Monterey Bay area. We do the concrete foundation work for room additions, garages, ADUs, shops and sheds. Every structural pour is built to the engineer's plans for that lot.

Our crew handles the layout, the excavation, the base, the forms and the steel. We set anchor bolts and hold-downs where the plans show them, then pour, finish and cure the slab. On a larger job we can run the whole project as your general building contractor under one permit set. Estimates are free. Call or text (831) 262-9943.

What We Handle

  • Slab-on-grade pours for room additions, garages, ADUs, shops and sheds
  • Perimeter foundations with continuous footings under stem walls
  • Excavation, grading and compacted base inside the forms
  • Rebar grids and footing steel tied on chairs, sized by the plans
  • Vapor barrier under the slab where the plans call for it
  • Anchor bolts and hold-downs set to the engineer's layout
  • Forms, screeds and slab finishing, broom or steel trowel
  • Forms and steel held for the building department inspection before the pour

Concrete slabs for additions, garages, ADUs and shops

Most of the slabs we pour sit under something new. A room addition, a detached garage, an ADU, a shop or a storage building all start the same way. We set the layout from the plans, dig the footings, then grade the pad inside the forms. Flatwork like walkways and steps is a different job, covered on our general concrete work page.

Compaction is the quiet part of a slab. Loose fill under fresh concrete settles later, and the slab cracks where it lost support. We compact in lifts and keep the base even, so the concrete sits on ground that stays put.

Then comes the steel. Rebar goes in a grid, tied and lifted on chairs so the steel sits inside the concrete. Where the plans call for a vapor barrier, it goes down before the steel. Anchor bolts and hold-downs are set to the plan layout while the concrete is still wet.

House foundations built to the engineer's plans

A house foundation is an engineered structure. The engineer sizes the footings, the steel and the connections for that lot and that building. Seismic design is their job here, and it shows up as bar sizes and hold-down callouts. We build to those plans.

On a slab-on-grade, the footings and the floor are poured together as one piece. On a perimeter foundation, a continuous footing carries a stem wall around the outside. The framed floor sits on top of that. A hillside lot may need a retaining wall cut in before the foundation can go in.

Either way, the footing depth, the rebar and the anchor bolt spacing come off the drawings. We check the forms and the steel against the plan before we call for inspection. Concrete is unforgiving once it sets, so the measuring happens first.

Soil, salt air and concrete slabs around the Monterey Bay area

Ground changes a lot inside our service area. Some valley floor and Hollister lots sit on heavy expansive clay. That clay cracks and shrinks when it dries, then swells again when it gets wet. A slab poured on an unprepared base is the one that feels it.

Near Marina and the former Fort Ord, the ground is old dune sand that drains fast. Sand like that needs real compaction to hold a flat, firm pad. Where a job calls for a soils report, that report sets the footing depth and the base detail. We build to it.

Freezing is rare on this coast, so freeze-thaw damage is not the local problem. Water, salt air and ground movement are. California's bridge engineers treat anything within 1,000 feet of the ocean as a marine atmosphere. They add concrete cover over the steel for it, and that thinking guides our coastal pours too.

FAQ

Foundations and Slabs Questions, Answered

Common questions about foundations and slabs across Salinas and the Monterey Bay area. If yours is not here, call or text and ask.

Call (831) 262-9943

What drives the price of a concrete slab?
Size and thickness come first, then the footings the plans call for. Access matters as well, because a back yard the truck cannot reach needs a concrete pump. Excavation, how much dirt leaves the site, the rebar schedule and the finish all move the number. Send your plans through our contact page or call or text (831) 262-9943 for a free estimate.
Do I need a permit, and who inspects the work?
A slab under a new structure is permitted work in most cases. Inside city limits the city issues the permit, and counties permit only the unincorporated areas. Pebble Beach, Carmel Valley and Prunedale go through Monterey County Housing and Community Development. The building department then inspects the forms and the steel before any concrete goes in.
What is the difference between a slab-on-grade and a perimeter foundation?
A slab-on-grade is one pour. The floor and the thickened footings go in together, and the floor sits on the ground. A perimeter foundation runs a footing and a stem wall around the outside, with a framed floor above it. Your plans, the slope and the soil decide which one you get.
How does the soil on my lot change the slab?
It changes what goes under the concrete. Some valley floor and Hollister lots sit on heavy expansive clay. That clay swells when it gets wet and cracks when it dries out. Near Marina the ground is old dune sand, which drains fast and needs real compaction.
Can you pour the slab for an ADU or a detached garage?
Yes. Both are common slab jobs for us. Footings, steel and the anchor bolt layout come off the engineer's plans for that structure. A detached shed of 120 square feet or less can fall under the state permit exemption, which cities may tighten.
What should I have ready before the estimate?
The plans are the big one. Send whatever the architect, designer or engineer has drawn, especially the foundation plan and its details. A soils report helps if the project has one. With no plans yet, we can still see the site and talk the pour through.
