Precision Starts with Self-Leveling Cementitious Underlayment

Self-leveling cementitious underlayment creates a flat, durable surface that’s ideal for installing commercial flooring systems. Whether you're correcting uneven concrete, preparing for moisture mitigation, or meeting glue-down flooring specs, this solution saves time and ensures a reliable, code-compliant base. Fast-curing and pumpable, it's built for large-scale projects and tight construction schedules.

Creates a Flat, Even Surface

Corrects imperfections in the concrete slab to meet flooring tolerances and ensure a smooth, floor-ready finish.

Speeds Up Installation Timelines

Fast-setting and pumpable formulations allow large areas to be covered quickly, reducing downtime on busy job sites.

Supports a Wide Range of Floor Systems

Provides a stable, high-strength base compatible with adhesives, coatings, and moisture mitigation systems.

Why Subfloor Prep Shouldn’t Be Skipped

When floors are installed over uneven or improperly prepped concrete, the risks show up fast—and so do the costs. Without self-leveling underlayment, your flooring system can fail before it even has a chance to perform.

Uneven Floor Surfaces: Visible waves or dips in the slab can lead to flooring defects, trip hazards, or adhesive gaps.
Installation Delays: Unprepped or out-of-spec slabs slow down crews and may require tear-outs or rework.
Adhesive and Finish Failures: Flooring adhesives don’t bond properly to rough or inconsistent surfaces, voiding warranties and leading to early failure.

How Self-Leveling Underlayment Solves the Problem

When you start with a properly leveled surface, everything else goes smoother—from floor installation to long-term performance. Uneven concrete creates ripple effects across the entire project, causing delays, rework, and early floor failure.

CustomCrete installs self-leveling cementitious underlayment systems that provide the flatness, strength, and speed today’s commercial builds require. Our process ensures your subfloor meets all adhesive and material specs—so you can move forward without costly surprises or surface-related setbacks.

Hear from past clients

"Used CustomCrete for a urethane cement flooring application (Carbocrete HF) in a harsh manufacturing setting where all prior epoxy/concrete flooring either popped off due to heat/moisture or was eaten through by our corrosive product.

The team was easy to work with and very responsive to changes in scope as well as working around other vendors during a plant turnaround."

-Jack Barkow

"We had a floor that had been painted several times and looked very abused. It was becoming difficult to keep clean and looking nice. Tom came in, pulled up all the paint, and brought the floor back to its original state. It now shines and is easy to maintain."

-James Petryka

"CustomCrete and their crew did a fantastic installation on my floor project. Any questions or concerns that I had were addressed by Tom himself. Very happy with the service they had provided to me."
