HDPE Floor Underlayment

Maximum Protection

Xmark Floor Underlayment shields carpet and hardwood floors against the dangerous and costly effects of mould, and mildew arising from water or moisture exposure. When water evaporates from bear concrete floors it is absorbed by the plywood. Moisture laden plywood creates an ideal breeding ground for mold. As moisture evaporates from the plywood it is absorbed by the hardwood floor or carpet.

Xmark Floor Underlayment works by separating the interior floor surface (tile, carpet or hardwood) from the concrete foundation floor. The High Density Polyethylene dimpled surface (5/16" high) elevates the plywood from the concrete foundation floor which
creates an air pocket underneath the underlayment to diffuse moisture evaporating from the concrete and minimize moisture transmission into the floors.

Features and Benefits

• Helps to prevent the warping of hardwood floors & development of mold
• 5/16" high dimples are able to support very high loads (i.e. 8000 lbs./ft2)
• Guards from the accumulation of moisture under flooring
