GreenLay™ is a unique installation method for resilient sports flooring that is exclusive to Tarkett Sports’ Omnisports 6.5mm and 8.3mm. It is 98% adhesive-free, tolerates moisture conditions up to 92% relative humidity per ASTM F2170, and saves costs relative to a moisture barrier. With less adhesive, GreenLay™ is also easier to remove and recycle at the end of its long life.
GreenLay™ was first developed and used by Tarkett Sports is 1995. The first installation was a gymnasium facing temperature variations and rising moisture levels due to a nearby river. Today, the same installation is in excellent condition and is still in use after 20 years, with no damage resulting from moisture conditions. Since 1995, there have been 12 million square feet of GreenLay™ installed worldwide with over 4 million square feet installed in North America. Most notably, there have been zero failures to date when properly installed. GreenLay™ has revolutionized sports flooring installations to become the new standard for performance and environmental responsibility.
GreenLay™ uses small amounts of adhesive on the perimeter of each court, doorways, and volleyball sleeves, while Tarkett’s Tarkotape secures each seam for welding. The Omnisports material itself does the rest. Its excellent dimensional stability and virtually tension-free manufacturing process make it the only resilient sports flooring that can be installed this way. In short, the superior qualities of Omnisports makes GreenLay™ possible.
- GreenLay™ reduces installation time by an estimated 20%, minimizing construction delays and excessive downtime for your gymnasium.
- Moisture tolerance is higher than traditional installations. GreenLay™ can tolerate up to 92% relative humidity per ASTM F2170.
- GreenLay™ is less costly than moisture barriers. In most cases, GreenLay™ can solve moisture problems at a fraction of the cost.
- Since GreenLay™ is 98% adhesive free, removing the floor for recycling is easier. There is also minimal adhesive contamination which may cause a recycling center to reject the material.
- During the installation process, GreenLay™ creates less waste associated with adhesive use. It requires a fraction of the containers used in a full adhesive installation, which must be transported to the project and then discarded afterwards. An 8,000-square-foot gymnasium can require as much as 64 gallons of adhesive, but a GreenLay™ installation typically uses less than 1 gallon.
Frequently Asked Questions
What makes GreenLay™ better than other minimal adhesive systems?
GreenLay™ adheres just around 2% of the surface area and can tolerate up to 92% relative humidity (ASTM F2170). This makes installation less dependent on moisture conditions. It also creates less waste, makes recycling easier, and even allows easier access to the subfloor. Other systems require more adhesive and may have lower tolerances for moisture.
Can I tell a difference between GreenLay™ and a fully-adhered Omnisports floor once it is installed?
No. The absence of adhesive does not significantly change performance of the floor. An Omnisports floor installed using GreenLay™ has the same sports performance properties (ASTM F2772) and other characteristics of a fully-adhered surface.
Can GreenLay™ withstand static and rolling loads?
Yes. Tables, chairs, portable bleachers, and carts have been used regularly on GreenLay™ installations for nearly 20 years. It has been tested with static loads up to 200 psi (ASTM F970) and rolling loads up to 1,500 N (EN 1569). However, with any flooring system, it is important that all equipment used on the floor be undamaged, clean, and designed for use with resilient flooring. For example, if a cafeteria table has a broken wheel or the weight distribution mechanisms are not engaging properly, the limits of any resilient floor may be exceeded. If there is a circumstance where higher load tolerance is necessary, Tarkett Sports offers Omnisports HPL, which can accommodate static loads up to 500 psi (ASTM F970).
How much faster is a GreenLay™ installation?
GreenLay™ is about 20% faster than a fully-adhered floor on average, but installation time varies depending on the project requirements. It accomplishes this by essentially eliminating the adhesive application process. There is also no waiting for adhesive to set before the floor can receive foot traffic. If you have a short window for installation or simply want to get things done faster, GreenLay™ may be the right solution for you.
Is there a higher chance of mold or mildew using the GreenLay™ system?
No. The Omnisports GreenLay™ system does not contribute to the growth of mold or mildew. ASTM G21 testing of Omnisports indicates “zero growth” of microorganisms on the material backing. Regardless of the sports flooring system, the risk of mold can be virtually eliminated by controlling site conditions. Mold requires a specific combination of factors to grow: moisture, the right temperature, a food source, and oxygen. To prevent mold growth, simply keep surfaces clean, dry, and well ventilated.
Why is GreenLay™ a better solution for end-of-life recycling?
GreenLay™ facilitates recycling in two ways. First, since there is very minimal adhesive used, the floor can be removed more easily. Second, the backing of the Omnisports surface remains adhesive-free. Adhesive contamination may cause some recyclers to reject the material, making it more difficult to recycle fully-adhered sports flooring. With GreenLay™, that obstacle is eliminated before the first basketball game is ever played on your floor.
