Product overview
NPF polymer self-adhesive membrane waterproofing membrane is a waterproofing membrane specially developed for underground engineering with international cutting-edge technology, which can provide a firm combination with the post-pouring concrete structure. It is a kind of special high-density thermoplastic polyethylene membrane as waterproof substrate, polymer self-adhesive film, anti-environmental change protective layer and isolation layer, which belongs to the non-asphalt-based polymer pre-laying waterproofing membrane!
Under the action of pressure, the polymer self-adhesive film and the cement slurry without initial setting in concrete penetrate through the anti-adhesive layer through creep, forming effective interpenetrating bond and huge intermolecular force. After the concrete is cured, the gap between the NPF polymer self-adhesive membrane waterproofing membrane and the main body of the structure is permanently sealed to the maximum extent, and the water channeling channel is completely eliminated.
