Your basement floor carries everything above it. We build them sealed, level, and ready for whatever finish you choose next. New construction or full replacement, every slab gets a vapor barrier, proper base prep, and a flat pour.
A basement floor that fails usually failed before the concrete was even poured. No vapor barrier means moisture rises through the slab for decades, destroying tile, carpet, and finishes. Uneven subgrade means the finished floor slopes, and every lippage and gap becomes visible. Rebar placed wrong or missing means cracks appear under load.
We start with the ground itself. Subgrade gets compacted, graded to plan, and inspected before any barrier goes down. The vapor barrier is sealed at every seam, not just laid loose. Rebar or mesh sits at the right height. Then the concrete goes down, gets screeded flat, and finished to match what comes next, whether that is tile, a polished concrete finish, or carpet.
This approach pairs with basement waterproofing when moisture is the issue, and with foundation work when the slab is part of a larger structural project.

The sequence
How a Basement Slab Gets Built Right
Measure and grade the subgrade
We establish the finished floor elevation, compact the existing soil, add gravel where needed, and bring everything to the right plane. Plumbing and radon stubs get protected.
Install vapor barrier and reinforcement
The sealed vapor barrier goes down with taped seams. Rigid foam or other underlayment is placed if specified. Rebar or wire mesh is positioned at the correct height for slab thickness.
Place and finish the concrete
Concrete is delivered, placed, screeded to a flat plane, and bull-floated. The final finish is adjusted for what comes next: smooth for tile, polished if the slab is the floor.
Cut joints and cure
Control joints are saw-cut on schedule. The slab is protected through cure. You get back a finished basement floor ready for trades to build on top.
When the old slab has to go
Diagnosing and Replacing a Failed Basement Floor
A cracked or wet basement floor usually signals a problem that started before the concrete was poured. Missing vapor barrier, poor drainage, settlement, or bad subgrade prep. Patching or overlaying a failed slab just repeats the failure.
We diagnose first. Sometimes a crack repair or interior waterproofing solves it. Often, only a new slab on a corrected base is honest. The estimate will tell you which path makes sense.
New builds, replacement slabs, vapor barriers and finish-ready floors in Las Vegas basements.
Yes, in Las Vegas basements where the ground is consistently damp, a sealed vapor barrier under the slab is essential. Without it, moisture migrates up through the concrete for decades and ruins finishes on top, no matter how good the slab itself is.
Yes, polished basement floors are a real option here. We adjust the finishing pass, then grind, hone and polish the slab to the gloss level chosen, and the basement floor itself becomes the durable, low-maintenance finish.
Yes. Cracked or wet slabs almost always have an underlying cause, missing barrier, bad drainage, settlement. We diagnose it, fix that, then pour a new slab on the corrected base so the new floor does not inherit the old problem.
Most residential basement slabs are several inches thick over the prepared subgrade, reinforced with mesh or rebar. Exact thickness depends on the slab's use and the engineer's spec; the quote ties to your build.
You can usually walk on it within a day or two, but moisture testing should drive when finishes go on top. We hand back the slab with cure-time guidance so the tile, plank or carpet above does not get applied too early.

What Las Vegas Homeowners Say About Their Basement Floors
They flagged the missing vapor barrier under our old slab before quoting. Re-poured properly, sealed seams. Two springs in, the new floor is dry. Total game-changer for the basement.

Polished basement floor and it looks incredible. They adjusted the finishing pass for the polish, then ground and honed it themselves. One contractor, slab to shine.

★★★★★
New build basement floor poured perfectly flat. The tile guys came in after and said it was the easiest install they had done all year. Their flatness call paid off.

★★★★★
Tore out a slab that had been pouring wet for years. They found the source, fixed it, then poured a new one. Honest sequence, honest quote. Basement is finally usable.
