Ecoply® Flooring

Ecoply® Flooring is ideal as a substrate for most floor coverings and flexible waterproofing membranes. It is particularly ideal for wet areas, where treated flooring is needed. It is also widely used for flexible and rigid overlay products such as carpets, linoleum, tiles and membrane systems or any application where a smooth substrate is required.
