Slab foundation building in Lancaster CA - square and level on well-prepared ground
Building a home, addition or shop in Lancaster and need a slab under it? We prep the ground first, then pour it square and level.
What a slab foundation job involvesin Lancaster, from the ground up
A slab foundation is a concrete slab your house sits on, poured right on the ground. Slab foundation building in Lancaster, CA is mostly ground work, because rebar, the steel inside the slab, can't make up for a weak subgrade, the dirt it rests on. So we dig out and pack the ground before anything else.
What moves the price is the slab's size, what it has to carry, how much digging and packing your lot needs and what type of slab your plans call for. The schedule turns on city plan review, inspections and the weather on pour day. I'll put your number in a written estimate.
You'll know what your slab needs and what it costs before we start, so call (661) 952-4153 and I'll come take a look.
Slab foundations we build
Every slab starts with the same ground work. Then we match the slab itself to the building, what it has to carry and what your plans call for.
Homes and additions
A slab poured right on prepared ground for a new house or addition. If your plans call for a raised floor instead, that's our foundation installation work.
Post-tensioned slabs
Steel cables run through the slab and get pulled tight after the concrete hardens, squeezing it together. We build these when your plans or your engineer call for one.
Shops and small commercial buildings
Slabs for garages, shops and small business buildings, set up for the loads they'll carry. For the paving around the building, see our concrete parking lot building page.
Why people hire L&M in Lancasterto get it right the first time
You deal with me from the first look, and we're known for slabs that come out square, level and the way we said they would.
The owner prices your slab
I come out myself to look at the site and measure, so the person writing your estimate is the same one who answers for the slab.
Owner on site for the pour
The work is done by a crew I trained, and I'm on site for the pour, because concrete only lets you get it right once.
Building since 2013
I learned under a foreman who made me tear out forms until they were dead straight, then started this business in 2013. That habit stuck, and the crew picked it up from me.

Call (661) 952-4153 or send the form with your address and any plans you already have. We'll set a time to come out and see the lot.
Site visit and estimate
We look at the lot, measure and ask what the slab has to carry. Then you get a written estimate that lays out what's included and what isn't.
Plans and city review
We go over your plans with you before the forms go up. On larger projects the city's first plan check is usually done within three weeks, so plan around that wait.
Ground prep and the pour
Our crew digs out and packs the subgrade, sets the forms and pours. The city makes periodic inspections during construction, so those visits are built into the schedule.
Finish, cure and walkthrough
We finish the slab and let it cure, the wait while concrete gains strength before it carries weight. Then we walk the job with you before we call it done.
Slab foundation questions
How much does a slab foundation cost in Lancaster, CA?
The price comes down to the slab's footprint and thickness, the loads it carries, how much ground work your lot needs and whether the plans call for a post-tensioned slab or an engineer. The place people want to cut is the ground prep, since nobody sees it once the slab's poured, and that's the last place I'd save money. I'll give you your number in a written estimate after I see the lot.
What causes cracks in a new slab foundation, and is that normal?
Some cracking and curling, where the edges lift a little as the slab dries, is normal on every project according to the national slab design guide, so a few cracks alone don't prove bad design or bad work. Cracks that keep growing or come with settling usually trace back to the ground under the slab, which is why we spend most of our effort there.
What is the best slab foundation for shrink-swell soil?
A post-tensioned slab is the one the post-tensioning industry group calls a cost-efficient, high-performance choice for homes on soil that swells when wet and shrinks when dry. The tightened cables keep the concrete squeezed together, and that built-in compression resists the strain of the ground moving, so it's worth weighing against a regular slab if your lot moves.
Do I need an engineer to draw slab foundation plans in Lancaster?
Usually not for a standard house, because Lancaster lets an unlicensed person prepare plans for wood-frame single-family homes up to two stories and a basement. If your home has unusual design features, the building official can require plans from a registered civil engineer or certified architect, so budget time for that if your design is out of the ordinary.
Does Lancaster have earthquake or liquefaction rules for slab foundations?
Yes, the city's building requirements include a reference on seismic hazard and liquefaction zones, and the state has found some properties likely to have weak soil or rock beneath them that can fail in an earthquake unless proper precautions are taken during grading and construction. State rules for those areas exempt a single-family frame home up to two stories that isn't part of a development of four or more units, but local agencies can be stricter. It's one more reason the ground work comes first on our jobs.
What is the best way to pour a slab in Lancaster's summer heat?
Pour early in the morning whenever you can and move fast, which is what a concrete trade group advises, with prompt transport, placing and finishing. Hot midday pours can leave a weak, dusty top later on. We set the pour time with you when we schedule the job.
