Underlays and Overlays

Correct structural unlevelness and repair deeply compromised subfloors with engineered leveling systems. Our premium self-leveling underlays and architectural overlays smooth out high spots, fill deep spalls, and restore flat, structurally sound bases ready for finish flooring or direct traffic.

SUBFLOOR RESTRUCTURING

Flawless Leveling and Capping for Imperfect Slabs

Do not let a wavy, damaged, or pitted concrete foundation ruin your flooring investment. Our high-flow self-leveling underlays and decorative toppings create flat surfaces that meet strict floor flatness (FF) specifications—providing a solid base for commercial or residential spaces.

What Are Concrete Underlays and Overlays?

Concrete underlays and overlays are specialized, cement-based compounds engineered to cap, level, and repair irregular subfloors. Underlays are highly fluid, self-leveling materials poured over structurally sound but rough or wavy concrete bases to build a smooth, flat surface hidden beneath carpet, tile, or hardwood flooring. Overlays serve as a durable, visible wear layer. They patch and cap worn concrete surfaces, and they can be mechanically polished, stained, or sealed to create a modern, high-strength architectural floor without requiring a full structural slab replacement.

Why Choose Underlays & Overlays

Structural correction, rapid installation—explore the technical benefits:

Precision Leveling Accuracy

Corrects dramatic slab deflections and waves to meet tight architectural flatness limits.

Saves Existing Slabs

Avoids expensive, disruptive demolition by capping damaged concrete with a thin, high-strength layer.

High Compressive Strength

Formulated with polymer-modified cement that handles heavy traffic loads without cracking.

Rapid Polymer Curing

Fast-setting formulas allow subfloors to accept foot traffic and finished flooring in hours.

FAQs About Underlays & Overlays

Answers to Common Questions Before You Get Started

 An underlay is a hidden structural layer designed to level out a bumpy subfloor so you can install a finish material like wood, tile, or luxury vinyl plank. An overlay is an exposed, durable wear surface that acts as the final floor itself, allowing it to be polished, stained, or sealed.

Thorough preparation is essential. We use mechanical diamond grinding to clear out contaminants, oils, and loose concrete, then treat the floor with a specialized high-bond primer. This primer seals the porous subfloor, preventing air bubbles and stopping the concrete from sucking moisture out of the new mix.

Our Process

Clear Steps. Quality Every Time.

We eliminate operational guesswork by strictly adhering to a transparent, disciplined multi-step execution workflow. Every project phase is precisely tracked to ensure absolute site safety, technical adherence to spec, and zero scheduling surprises.

Here’s How We Bring Your Vision to Life:
