01The problem
A slab looks flat. Until it isn't. The driveway pools water at the door. The patio cracks at a joint that wasn't there. The garage floor pulls away from the foundation in winter.

Slabs that pour clean, set true, and last.
CSLB #917675Since 1998Serving 5 Bay Area counties
Why now
Concrete Slabs done late costs more than concrete slabs done right.
02What it costs you
A bad slab is a daily reminder. Cars drag. Water finds the basement. Cracks widen each freeze-thaw cycle. The patch costs more than doing it right the first time — and the patch never matches.
03What we do
We pour driveways, patios, sidewalks, garage floors, and ADU pads — clean lines, true levels, integrated drainage. Bay Area soil prep, the right joint spacing for whatever's going on top, and the C-36 plumbing license that lets us coordinate slab rough-in without a second contractor on site. CSLB #917675 (B · C-8 · C-36).
What’s included
Every concrete slabs project, every line item.
You see the whole scope before any concrete is poured. Nothing hidden, nothing quietly billed mid-project.
- Site grading and base prep with compaction in lifts
- Crushed-rock base appropriate to soil and load (typ. 4–6")
- Vapor barriers under interior slabs (kitchens, garages, ADUs)
- Edge forms set true with string-line verification
- Reinforcement: rebar mat or welded wire mesh per design
- Plumbing rough-in coordination during pour (we hold the C-36)
- Conduit pass-throughs for electrical and EV-charger pre-wire
- Continuous concrete pour to avoid cold joints
- Saw-cut control joints within 24 hours to prevent random cracking
- Surface finishes: broom, smooth-trowel, exposed aggregate, salt finish, or stamped
- Curing per spec (typ. 7-day wet cure or curing compound)
- Drainage tie-ins (deck drains, French drains, downspout extensions)
- Site walk-down and post-pour clean-up
How we do it
The concrete slabs process — every job, in order.
The same rhythm whether the job is a $12,000 footing or a $200,000 structural retrofit. Owner on site, same crew, same standards.
- 01Step 1 / 6
Visit & quote
Jose walks the area, measures elevation, identifies drainage and load. Written bid that specifies thickness, mix design, finish, and joint pattern.
- 02Step 2 / 6
Demo & sub-prep
Existing slab removed (or area excavated); base graded and compacted to engineered depth. Vapor barriers laid where called for.
- 03Step 3 / 6
Forms & rough-ins
Edge forms set, rebar or wire mesh laid, plumbing/electrical rough-ins coordinated and pressure-tested before the concrete arrives.
- 04Step 4 / 6
Pour & finish
Concrete poured continuously, screeded, floated, and finished to the specified texture. Control joints saw-cut within 24 hours.
- 05Step 5 / 6
Cure
Slab kept moist (or sealed with curing compound) for 7 days. We don't move equipment or load-bear on it until cure is complete.
- 06Step 6 / 6
Walk-down
Forms stripped, joints sealed where needed, drainage tested, site cleaned. We hand it back ready to use.

Don’t see your question? Call (650) 754-3064 and ask Jose directly.
Q01How thick should my slab be?
Depends on use. Sidewalks and patios: 4 inches. Standard residential driveways: 4–5 inches. Heavy-use driveways (boats, RVs, dumpsters): 6 inches. Garage floors: 4 inches. We spec each in the bid — no surprises.
Q02Will my new slab crack?
Concrete cracks. We control where. Saw-cut control joints (typ. every 8–12 feet on a driveway) tell the slab where to crack — clean lines along joints, not random across the surface. Reinforcement holds those cracks tight.
Q03How long until I can drive on it?
Walking: 24–48 hours. Light vehicle traffic: 7 days. Full load (loaded truck, RV): 28 days minimum. We mark the cure timeline in the bid so you can plan around it.
Q04Can you do a stamped or exposed-aggregate finish?
Yes. Stamped looks like flagstone or brick at slab cost — we have pattern catalogs. Exposed aggregate brings the rock to the surface for a textured, slip-resistant finish. Both are priced higher than broom finish and worth it for visible-from-the-street work.
Q05Do you handle the rough-in plumbing or conduits?
Yes — the C-36 license is part of why we exist as a one-call solution. Floor drains, EV-charger conduits, irrigation tie-ins, and rough-in for ADU plumbing happen as part of the slab, not a second mobilization.
Q06What about drainage — will it pool?
We grade for slope (typ. 1/4 inch per foot away from structures). Where slope alone isn't enough, we tie deck drains or French drains into the slab during the pour. We don't pour first and patch the drainage problem later.
