A slab foundation that starts with the ground
At J&R Santa Rosa Concrete Construction, slab foundation building usually starts with a call about a new house, an addition or a shop. We form the edges and set the rebar, the steel that holds the concrete together. Then we pour and finish it so the top stays level while wet and dry seasons move the soil. For a raised floor, see foundation installation.
Before I bid, I check with the city or county office for your address. Permit Sonoma's county policy calls for a soils report, a study of the ground, which may be waived only when data show no hazards. The slab's size, the soil and how far above code you build drive the price. Soil work and cure time set the schedule, and your written estimate spells out both.
Choices for your slab foundation
Get a quoteCode-minimum slab
The building code sets the least a slab needs for safety, and nothing lower is allowed. It can suit a simple building on stable ground.
Built above code
Code is the floor, not the goal. You can ask for more, and we'll go over where building above the minimum is worth it on your lot.
Post-tensioned slab
Some home slabs use steel cables, called tendons, tightened after the pour. If you're weighing one, ask each bidder whether their crew holds PTI field certification.
Shop or commercial pad
For a shop or small commercial building, we plan the slab with the paving around it, including concrete parking lot building if you need it.

Why owners hire us for slab foundations
The owner at estimate and pour
I come out to every estimate and I'm on site on pour day. Our own crew does the work, so the person who priced your slab watches it go in.
In business since 2021
I started this business in 2021 after years on other crews. Before every pour I still check the moisture layer, the plastic under the slab, for tears and patch them.
Licensed and fully insured
We're licensed and fully insured. When your slab needs a permit, we handle the application and meet the inspector, and the estimate says so up front.
