Precision Self-Leveling Concrete for Boston Facilities
A slab that's out of spec stops finish flooring dead. Self-leveling concrete is the precision fix: we grind, prime, and pour a bonded underlayment that brings your existing slab to the exact flatness your tile, plank, or polish installer needs. No tear-out, no months of downtime. Boston Concrete handles the whole sequence from measurement to cure. Free written estimate.
Most Finish-Floor Failures Start With the Slab Itself
Lippage in tile, gaps in plank, roller marks in coating, inconsistency in polished concrete, these problems get blamed on the finish installer, but the real culprit is usually a slab that was poured outside the flatness tolerance for that finish. No finish installer can make a wavy slab look flat.
Self-leveling concrete fixes the slab first. We diamond-grind the existing concrete to expose a clean surface, apply a bonded primer, pour the self-leveling underlayment to your target depth, and let it cure to the finish-flooring spec. The result is a slab that meets the tolerance your finish requires.
We survey the existing slab to find high and low spots, calculate the depth needed to reach your finish flooring's tolerance, and confirm the plan with your finish-floor contractor before we schedule the pour.
Grind and prepare
The slab is diamond-ground to remove old coatings and expose clean concrete, contaminants are cleaned away, and a bonded primer is applied to ensure the new underlayment adheres fully to 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.
Cure and handoff
The pour cures on the manufacturer's schedule, the surface is verified against your finish-flooring tolerance, and the slab is ready for your tile, plank, polish or coating installer to begin.
Coordination matters
Self-Leveling Works Best When Scheduled Early
The best outcomes happen when self-leveling is planned into the build sequence with your finish-flooring trade, not added as an emergency fix. We coordinate the target tolerance with your tile, plank, or polish installer up front, agree on the depth, and pour to that spec.
On larger builds, we also sequence around adjacent polished slab zones, epoxy floor sections, and any floor repair that needs to happen first. The goal is a single, coordinated pour that sets up all the finish work to succeed.
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.
Client reviews
What Boston 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.

Retail Build-Out Director, Cambridge
★★★★★
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, Somerville
★★★★★
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.
