Garage floor concrete in Malibu, CA - a floor built for what you park and coat

Cracked, dusty or sunken garage floor? We pour a new slab built for your vehicles and ready for the coating you plan.

Polished dark gray concrete garage floor reflects the light in a mint-green garage with wooden sliding doors.

What's involved in replacing or pouring a garage floor in Malibu?

Garage floor concrete is flat concrete our crew forms, pours and finishes into a floor that carries your cars, and in Malibu we build it around what you park and whether you'll coat it. Plan on more than the pour day, since the slab needs time to cure before you drive on it, and any city approvals come before that.

Most people call when the old floor has cracked across the middle, sunk by the door or gone dusty where the car sits, or when a rebuild needs a new floor from scratch. The price moves with the size of the garage, how much old floor needs concrete cutting and hauling, how easy it is to get equipment to the door, how heavy your vehicles are and whether a coating is planned. The schedule turns on approvals and on curing, the wait after the pour while the concrete hardens, and before we price anything I look into what the city asks for at your address and tell you what I found. Your written scope then puts a price on each of those items for your garage.

How we build garage floor concrete

Before we pour, I ask what you park and whether you plan to coat the floor, because both change how the floor and the moisture barrier under it get built. On a replacement, our crew breaks out the old floor and hauls it away, then digs out and packs the subgrade, the layer the slab sits on, instead of raking it level, so the new floor doesn't settle with the dirt. Next come the moisture barrier and the rebar, steel set inside the slab to hold it together, and then we pour, finish the surface and slope it so water runs out the door, not back toward the house. If the budget gets tight, I'd cut the finish before I'd cut the base, because nobody sees the base on day one but it decides whether the floor stays flat, and a plain finish on a solid base outlasts a fancy one on loose fill.

A garage job often ties into the work around it. If you want color or a pattern on the apron outside the door, that's our decorative concrete work, and on a hillside lot, a garage cut into the slope sometimes needs concrete retaining walls along the side or back before the floor goes in.

Replacing a cracked or sunken floor

This suits a garage that's sound but has a floor that's cracked, settled or crumbling, since we can usually break out the slab, rebuild the base and pour new without disturbing the walls. We check how the new floor meets the existing walls and the driveway at the door, so the edges line up and water still runs out.

A new floor in a new or rebuilt garage

This suits a rebuild or an addition, where the floor goes in as part of the larger project and follows your architect's or engineer's plans. We set the floor's height, slope and what goes under it to match the drawings, and we time the pour with the rest of the foundation work.

Why Malibu homeowners call True North Malibu Concrete for garage floors

I measure your garage myself

I come out to look at the garage and take the measurements myself, and I'm on site with our crew when we do the work. On a rebuild, we work alongside your engineer, architect or soil consultant, so the floor we pour matches the plans they've drawn.

Fully licensed and insured for concrete work

We're fully licensed and insured. In California, the Contractors State License Board lists the C-8 Concrete Contractor class for contractors who form, pour, place and finish flat concrete, and a garage floor is exactly that kind of work.

What goes under the slab, written down

I started this business in 2023 after years running a sign shop, where a job was only right if every measurement was right. Your scope spells out what goes under and into the floor before any work starts. Call (424) 388-5404 to set up a visit.

Send the form or call (424) 388-5404 with your garage size, what you park and any coating plans, and we'll reply within one business day by phone or message. The estimate is free, done at your property and comes with no obligation. I measure the garage, look at access and the old floor, and send you a written scope with a price you can compare line by line.

Garage floor concrete rules in Malibu

All of Malibu sits in the coastal zone, and development there generally needs a coastal development permit from the state Coastal Commission or the city before work starts. Your job starts with the city's Planning staff, who decide whether it needs review or is exempt, and only after Planning approves it does it move on to Building Safety, with requests going through the city's Development Portal. If the plans go to geology review, the City Geologist looks at the reports and plans. We plan the start around whatever approvals your job needs, and we can handle the concrete side of the paperwork or work alongside your architect or engineer.

Taking out an old garage floor leaves a pile of broken concrete, and the state's green building code and the city require construction and demolition projects to recycle or reuse at least 65% of their waste. Any hauler not on the city's permitted hauler list is working in Malibu illegally, so ask us which hauler is taking your old slab. Here we see cracked floors in older garages and new floors going into rebuilds, and we take the same work in Calabasas, Topanga and many other cities around Malibu, so just ask when you call if you're not sure we cover your address.

Garage floor questions we hear in Malibu

How much does a new concrete garage floor cost in Malibu?

A garage floor slab in Los Angeles County usually costs about $8 to $15 per square foot. That's the going rate around the county, not our quote, and the things listed at the top of this page decide where your floor lands. Your written scope shows each of them priced for your garage.

Does a truck or RV need a thicker garage floor than a car?

Usually, yes. A concrete industry group in Alberta, Canada, recommends a thicker minimum slab for trucks and recreational vehicles than for cars. Tell us what you park when I come out, because it sets how thick we pour, and the thickness goes in your estimate.

What causes cracks in a new concrete garage floor?

Most new slabs crack somewhere as they dry, so the goal is to decide where. Control joints, lines cut or formed into the slab, create planned weak spots so cracks happen along them instead of wandering across the floor. The other common cause is a base that was raked level instead of dug out and packed, which is why we put the time into the base work described above.

Do I need a permit for a new garage floor in Malibu?

Probably, in some form, because all of Malibu is in the coastal zone, where development generally needs a coastal development permit first. Planning staff decide whether your project needs review or is exempt, as covered in the Malibu section above. For questions about your own lot, the office that serves your address has the final word.

How long before I can drive on a new concrete garage floor?

Not until the slab has cured, so plan on being out of the garage for longer than the pour day. Curing depends on time, temperature and keeping the concrete from drying out, and it has to start right after the final finish, so we keep the new floor protected and off-limits until it's ready. I'll tell you when it's ready for foot traffic and when it's ready for your car.

Should I decide on an epoxy coating before my garage floor is poured?

Yes, tell us before the pour. One concrete industry guide says to choose the vapor retarder, the moisture barrier under the floor, based on what will go on the surface, so a coating plan changes what goes under the slab. The epoxy itself goes on after the slab cures and is budgeted separately from the concrete.
