Gypsum Underlayment

Gypsum Underlayment Benefits

Floor Technologies uses Maxxon® Gyp-Crete® (a lightweight mix of gypsum and concrete flooring) and sound control mats to offer these benefits to your new or updated building:

  • Keep Secure with Less Pressure on Framework – Compared to concrete, Gyp-Crete® is 28% lighter and much easier to work with. Plus, it’s almost entirely self-leveling and durable with compression strengths up to 4,500 psi.
  • Quick Dry Time, Faster Projects – Gyp-Crete® pours and dries fast, so it’s open to foot traffic only hours after installation.
  • Minimize Noises – Gyp-Crete® floors are perfect for minimizing noises when paired with sound control mats.
  • Ideal for Radiant Heating – Underfloor heating and Gyp-Crete® are the perfect pair to avoid corrosion and shrinking that might occur with regular concrete.
  • Clear Air and Reduce Toxins – Keep safety at top of mind with low chemical emissions in the gypsum and concrete mixture.

Cement Underlayment

Cementitious Underlayment Benefits

Floor Technologies uses Maxxon® Level-Right®, a self-leveling, hydraulic cement-based underlayment, to smooth rough, spalled concrete slabs with a featheredge.

  • Fast, Easy Installation – The easy-to-use, self-leveling mixture installs quickly, so your floor installation takes less time.
  • Ideal for Rough Screed Finish – Top off rough floors with strong cementitious flooring (compression strengths up to 7,000 psi) to provide a smoother underlayment.
  • Update Old Flooring – Self-leveling cement underlayment repairs old floors by smoothing out imperfections quickly without having to remove old material.
  • Save Money – Instead of replacing the entire floor, you can simply update the old underlayment with cementitious flooring over the top.
  • Perfect for Commercial Projects – Cement flooring doesn’t require a ton of prep, no removal is necessary in many situations (shot blasting is occasionally needed), and large projects are finished fast.

Cementitious Floors

High-strength and cost-effective, Maxxon® Level-Crete™ is a hydraulic cement flooring that’s perfect for capping uneven, rough, or spalled concrete floors in renovation projects.

Cap concrete, existing floors, and adhesive residue with the a self-leveling hydraulic cement-based underlayment. Level-Right® doesn’t require a lot of special prep or floor removal, so every project is finished fast.

Chemically Abated Slab Solutions

Chemical slab abatement can lead to product and installation failures when chemicals penetrate the concrete and later compromise the integrity of recently installed floors.

Maxxon® Commercial Isolate protects your flooring systems by blocking the migration of moisture, destructive abatement chemicals and other absorbed contaminants.

Adhesive Remover

Maxxon® Unglued is highly effective in removing PSAs, flooring mastics, glues, and adhesives with remarkable efficiency. Its fast-acting formula typically takes only 2-4 hours to dwell, depending on site conditions, ensuring quick results. What’s more, it’s non-toxic, non-caustic, and fully biodegradable, aligning with environmentally conscious practices. Additionally, its low odor means it doesn’t necessitate forced ventilation, providing a more pleasant working environment for all involved.



Cleaner and Profiler

Maxxon® Profile simplifies the surface preparation process by offering a clean and profiling solution without the need for shotblasting. It’s a user-friendly, spray-applied cleaner and profiler directly applicable to concrete surfaces. With this solution, achieving Concrete Surface Profiles (CSP) of 1-4 is achievable without the use of shotblasting equipment. We ensure a dust-free removal of densifiers, dirt, and efflorescence, making cleanup easy due to its biodegradable nature. Profile aids in lowering the concrete surface pH, allowing for subsequent treatments or coatings.

Decorative Concrete Topping

Maxxon® VersaTop™ offers a variety of affordable looks and is compatible with a wide range of sands, including locally sourced ones. It holds aggregate at the surface, reducing grinding needs, and can be ground easily the next day or later. With compressive strengths above 5,000 psi, it’s perfect for commercial, retail, and institutional projects.

Frequently Asked Questions

FAQ – Underlayments

If you are new to underlayments, you may have a few questions about the process. Read below to find the answers and contact us if you have more questions or if you’re ready to get a free quote.

Both IIC and FIIC are a measure of how soundproof a material is. But you might be wondering, what’s the difference? IIC is “Impact Insulation Class” and FIIC is “Field Impact Insulation Class”. IIC is the rating that a lab determines while FIIC is determined by an on-site test. This measure is based on how well a material dampens impact noises (footfall, scraping, jumping, etc.). The higher the IIC, the better acoustic insulation a material has to increase sound resistance (multifamily buildings aim for 55 FIIC).

It can get confusing keeping track of all the different layers in flooring, but there are four basic pieces: joists, subfloor, underlayment, and the floor covering.

  • Joists – Wood pieces that act as the foundation and frame for the flooring
  • Subfloor – Plywood layer that provides structure beneath the underlayment
  • Underlayment – Layer that provides a smooth, flat, and sturdy surface for flooring
  • Floor Covering – Last part of the flooring, often covered by carpet, tile, vinyl, and other flooring options

If you want a strong, durable flooring layer that lasts for years, then the answer is yes, you need underlayment. This layer of flooring protects from mold, mildew, and moisture. But it doesn’t stop there. It also helps increase sound and fire resistance in your home.

Sound control mats add an extra layer of material that works as a shock absorber. The materials absorb the vibrations caused by loud noises in a building. As a result, quieter floors occur in multifamily and commercial buildings.
