PP PE waterproofing membrane is a composite sheet membrane made of soft polyethylene(PE) with nonwoven polypropylene(PP) fabric laminated on both sides to enable the membrane fixed firmly onto mortar.
PP PE waterproofing membrane is flexible and conforms to various contours of the wood framing, bending upward at the walls and folding into corners. It can be applied directly with thin-set mortar, ceramic and stone tile, provides waterproofing and crack isolation/joint bridging for thin-set installations of ceramic and stone tile. It has been an ideal membrane to protect the substrate from moisture penetration.
PP+PE+PP composite waterproof membrane is made by multiple-ply different materials, especially its aging and weathering resistance layer enables the membrane possess more longer effective age. It can bond with many kinds of adhesions, firm and secure. In case of cement-base, cementations agent can be used, the cementations agent can easily enter into the non-woven felt layer, forms a well-combination with cement after solidification, permanent durability.
