Concrete Flattening & Self Leveling
Why Concrete Flatness Matters
Many flooring manufacturers specify strict flatness tolerances before installation. An uneven slab can affect the appearance, performance, and longevity of your new floor.
Common problems caused by an uneven subfloor include:
- Hollow spots beneath flooring
- Uneven finished floors
- Loose or cracked tile
- LVP movement
- Hardwood deflection
- Adhesive failures
- Gaps and squeaks
- Premature flooring wear
Proper subfloor preparation helps prevent these issues and supports a long-lasting installation.
At Leader Flooring, we specialize in professional concrete flattening and self-leveling using premium Bostik primers and self-leveling underlayment’s because their work seamlessly with the moisture mitigation and adhesive products. Our experienced technicians evaluate each slab, identify high and low areas, and use the proper preparation methods to create a smooth, stable surface that meets flooring manufacturer requirements.
Frequently Asked Questions
Not necessarily. Some floors only require grinding or patching, while others benefit from a self-leveling underlayment. We evaluate each project individually.
We use professional laser levels, long straightedges, and other measuring tools to compare the slab against the flooring manufacturer's flatness requirements.
Yes. When the concrete is properly prepared and primed, self-leveling underlayment’s can create a smooth surface over most structurally sound slabs.
Primer improves adhesion, helps control substrate absorption, and supports the overall performance of the self-leveling system.
Yes. An uneven subfloor can contribute to movement, hollow spots, cracked tile, adhesive issues, and premature wear if not corrected before installation.
Our Concrete Flattening Process
1. Concrete Inspection
Every project begins with a detailed inspection of the slab. We evaluate flatness, identify high and low areas, and determine the most effective preparation method.
2. Straightedge
Using professional laser levels, straightedges, and measuring equipment, we map the concrete surface to locate areas requiring correction.
3. Surface Preparation
Proper surface preparation is essential. Depending on the condition of the slab, we may:
- Grind high spots
- Remove adhesives
- Repair cracks
- Clean contaminants
- Vacuum the surface
- Prepare for primer application
4. Premium Primer
The appropriate primer is applied to improve adhesion and prepare the substrate for the self-leveling underlayment.
5. Self-Leveling Underlayment Installation
Our technicians use professional mixing equipment to install self-leveling underlayment’s. The material is poured, distributed with a gauge rake, and finished with a spiked roller to produce a smooth, uniform surface.
