Tyroc Underlayment


Tyroc is a composite underlayment designed to be installed over new or seasoned concrete floors, such as those in basements. It is impervious to mold, mildew, and moisture. Once installed over a concrete floor, Tyroc panels provide a warm, clean, and dry surface for your finished flooring. Helps eliminate noisy floors, carpet bubbles, and carpet expansion. Tyroc is designed to be flexible and automatically adjusts to minor variances, cracks or pitting in a concrete floor; no leveling shims are required for installation.

Other Green Info: Tyroc eliminates millions of used tires and plastic water bottles from landfills. The molded composite rubber base is made of 60% recycled rubber tires and 40% post-consumer recycled plastic bottles. In a typical basement renovation of 500 square feet, Tyroc overflooring will use 12.5 recycled car tires and 93 pounds of recycled plastic bottles. The surface board is made with water at ambient temperature from magnesium oxide: a natural, fireproof, inorganic material. The choice of this material eliminates the need to cut down millions of trees each year to make subfloor products for homes in Canada and the US.
