According to the production process, it can be divided into needle-punched sodium bentonite waterproof blanket, needle-punched film-coated sodium bentonite waterproof blanket and adhesive-coated sodium bentonite waterproof blanket. The needle-punched film-coated method is to compound a layer of high-density polyethylene geomembrane on the outer surface of the non-woven geotextile of the needle-punched sodium bentonite waterproof blanket; the adhesive method uses an adhesive to bond bentonite particles to a high-density polyethylene board for compression production.
