Uneven Slabs Need Self-Leveling Concrete in Boston
When a basement, kitchen or addition slab sits uneven, self-leveling compound is the fastest way to bring it flat without tearing it out. We prime the substrate, pour the leveler, and let gravity do the work. The result is a sound, flat surface ready for tile, plank, polish, stain or any other finish. Call for a free written estimate.
Tile cracks when the slab dips. Vinyl plank shows lippage at seams when the concrete humps. Polished concrete looks patchy because the grind catches every low spot. These are not finish failures, they are substrate failures. The slab was never flat enough to begin with.
Self-leveling compound solves this by filling the low spots and settling to a true plane. We prime the substrate first (concrete, plywood, or existing tile all take different primers), mix the leveler to the manufacturer's water ratio, and pour it onto the floor. It flows under gravity, finds level on its own, and cures into a hard, bonded surface.
Once the leveler cures, the finish goes on a slab that is actually flat. Epoxy coats smooth. Stain colors evenly. Polish shines without telegraphing. Micro-topping lays seamless. The homeowner gets the floor they wanted, not a compromise.

The sequence
How We Pour Self-Leveling Compound in Boston
Measure the slab and pick the product
We laser-scan the substrate to find high and low spots, confirm it is dry and sound, and select the self-leveling product and primer matched to the substrate type.
Prime and set the perimeter
The substrate gets primed with the manufacturer-matched primer. We dam the perimeter so the leveler stays where it should and does not run into adjacent spaces.
Mix and pour to elevation
The self-leveling compound is mixed to the published water ratio, poured onto the primed substrate, and gently guided to the marked elevation. Gravity handles the rest.
Cure and finish
The compound sets to walkable in hours and cures fully over the manufacturer's window. The new surface is flat, hard, and ready for the finish layer without additional prep work.
Common applications
Kitchen Renovations, Basements, Tile and Plank
Renovation floors are the most common use case. Old slabs in Boston homes, patched slabs, slabs in additions rarely sit at the flatness modern finishes require. Self-leveling underlayment turns them into a usable substrate without a tear-out and haul-away.
It also goes under polished concrete when the slab is not polish-ready, under micro-topping when extra fill is needed, and under heated floor systems as part of the radiant heat stack. The flatness is what every system above depends on to perform.
When you need it, what it bonds to, thickness and finishes above in Boston.
Not always. If the substrate is already within tolerance for the finish you want, self-leveling is unnecessary. We measure first; if the dips and humps fall outside what the finish can handle, self-leveling is the honest fix.
All three, with the right primer and product for the substrate. We pick the matched primer and self-leveling product for what the floor sits on, so the bond is engineered for the surface, not assumed.
Most products handle up to about an inch in a single pour, more in lifts with proper bonding. We size the pour to the substrate's worst dip and the finish's flatness requirement.
No, it is a finishing prep, not a structural floor. It bonds to a sound substrate and brings it flat. If the slab below is structurally compromised, that has to be fixed first.
Walkable in a few hours, ready for tile or plank typically the next day, ready for polishing or staining once fully cured to the manufacturer's published window. We give you the exact timeline on the project.

What Boston Homeowners Say About Their Self-Leveling Pours
Old kitchen slab was a wave. Self-leveling brought it dead flat and the tile went down without a single shim. The result looks like a brand-new build.

★★★★★
Polished the basement floor after a self-leveling pour. The polish was perfect because the substrate was actually flat for the first time.

Plywood substrate in our addition. They primed it properly and the leveler bonded so well I forgot it was on plywood. The plank floor sits perfect.

★★★★★
Heated floor underlayment plus self-leveling plus micro-topping plus polish. Whole stack done in sequence and the finished floor is dead flat with even radiant heat.
