There are situations when a membrane is required to provide for separation of your playground equipment from dirt below. We suggest a material such as a polyester non-woven, needle-punched geotextile fabric. This is resistant to biological and naturally encountered chemicals, alkalies, acids, and ultraviolet light exposure. Visit us online at DunRite Playgrounds for more information
