Preparation of polyethylene high-strength polypropylene fiber composite waterproof craftsmanship. The project quality inspection and inspection personnel fill in the quality inspection and acceptance records. Waterproof layer construction shall not be carried out on rainy days. If it is not possible to reserve the groove, first fix the end to the wall with a gasketed nail or a metal bead, seal it with a sealing material, and press the metal or synthetic polymer strip with a bead to cover the cover. Seal the entire wall with a sealing material or use polymer cement mortar to bury the entire end.

It has strong impermeability, high tensile strength, good low temperature flexibility, rough profile of friction coefficient, non-toxicity, resistance to root puncture, high temperature resistance, aging resistance and invariance. Hot air welding can be used, but the high-strength polypropylene fiber non-woven fabric is covered by the profile or the back. It will be damaged before the welding, so the construction is complicated and the joint strength is not reliable.
