Fixing Out-of-Tolerance Slabs with Self-Leveling Concrete
A commercial slab that doesn't meet flatness specs becomes a problem the moment finish flooring is scheduled. Self-leveling concrete is the solution: we prime the existing slab, pour a self-leveling underlayment to the target depth, and deliver a flat surface ready for tile, plank, polish or coating. Las Vegas Concrete handles the measurement, the pour, and the coordination with your finish-flooring trade. Free written estimate.
Tile lippage, plank gaps, coating inconsistency, polished-floor streaking, these failures are often blamed on the finish installer when the root cause is a slab poured outside the flatness tolerance for that finish. No finish installer can make a wavy slab look flat. The slab has to be corrected first.
Self-leveling concrete addresses the slab directly. We diamond-grind the existing surface to expose clean concrete, apply a bonded primer, pour the self-leveling underlayment to the target depth, and allow it to cure to the finish-flooring spec. The result is a slab that meets the flatness requirement, which makes the finish install succeed.
How Self-Leveling Concrete Gets Poured in Las Vegas
Survey and plan
We measure the existing slab elevation across the entire floor, identify high and low spots, calculate the pour depth needed to meet the finish-flooring tolerance, and confirm the plan with the finish-floor contractor before work begins.
Prepare the substrate
The slab is diamond-ground to remove contaminants and old coatings, exposing clean concrete. A bonded primer matched to the self-leveling system is applied to ensure full adhesion between the new pour and the existing slab.
Mix and pour
The self-leveling material is mixed to the manufacturer's water ratio, poured to the calculated depth, and gauge-raked to distribute it evenly. The material self-levels to a flat plane within minutes of placement.
Cure and handoff
The pour cures on the manufacturer's schedule. Once cured, the slab is verified against the finish-flooring tolerance and handed to the finish installer ready for tile, plank, polish or coating application.
Coordination matters
Self-Leveling Works Best When Scheduled with Finish Trades
Self-leveling concrete delivers the best results when it's planned into the build sequence with the finish-flooring trade, not added as an emergency fix. We coordinate timing and tolerance with the tile, plank or polish installer from the start, agree on the target flatness, and pour to that target.
Tolerance specs, primer systems, depth ranges and when to self-level before finishing.
Each finish has its own tolerance, large-format tile is more demanding than plank, polished concrete more than tile. The finish installer's spec defines the target; we pour self-leveling to meet that target, and we will get the spec from your finish-flooring trade up front.
Yes, modern self-leveling systems can be poured at a thin overlay depth for minor tolerance corrections, up to several inches for major fixes. The system spec changes with depth; we use the right one for the pour.
Always. The primer is what bonds the new pour to the existing slab; without it, the self-leveling delaminates over time. We use the manufacturer-matched primer for the system, applied to a diamond-ground substrate.
Foot traffic typically within hours, but finish flooring usually waits longer for the pour to cure and dry. We give the finish-flooring trade the cure timeline so they can schedule their install.
Cost and disruption. A self-leveling overlay corrects the existing slab without tear-out, in a fraction of the time and budget. Where the existing slab is structurally failing rather than just out-of-tolerance, a new slab is the right call; we will tell you which case yours is.

What Las Vegas Operations Say About Their Self-Leveling Pours
Tile contractor had refused to install on our out-of-tolerance slab. Self-leveling pour brought it to spec inside three days; tile install went perfectly after that. Fixed the actual problem.

★★★★★
Coordinated with our polished-concrete trade from day one. Target tolerance agreed, pour hit it, polish came out flawless. Real trade coordination, not just a contractor.

★★★★★
Existing slab had two inches of variation across the floor. Self-leveling brought it flat, finish coating installer was thrilled. Cost a fraction of a new slab pour.
Y. V.
Property Manager, Boulder City
★★★★★
They were honest that part of our slab needed structural repair, not just self-leveling. Did both in sequence. The honesty was worth the slightly bigger scope.
