Polyethylene polypropylene fiber and high-polymer cement mortar composite waterproof roll and construction method thereof

The invention discloses a polyethylene polypropylene fiber and high-polymer cement mortar composite waterproof roll and a construction method thereof. The composite waterproof roll is prepared by the steps of firstly flatly laying polyethylene polypropylene fiber cloth on a base layer, then flatly laying glass silk gridding cloth, brushing a flexible polymer mortar material to the glass silk gridding cloth, and carrying out airing, forming and trimming, rolling and packaging. The construction method comprises the following steps: firstly cleaning up the basic layer, wetting the basic layer through spraying, and blending high-molecular polymer dry-mixed mortar with water to obtain paste; uniformly laying the blended high-molecular polymer dry-mixed mortar to the processed basic layer, then laying the composite waterproof roll, finally uniformly pouring the blended high-molecular polymer dry-mixed mortar to the laid composite waterproof roll, and uniformly brushing. The composite waterproof roll is convenient to use, and rapid to construct, and furthermore, a waterproof system is safe and reliable; the composite waterproof roll simultaneously has the characteristics of high strength, freeze resistance, strong weather resistance and the like of a rigid waterproof material as well as the characteristics of good tensile strength, strong waterproof performance and the like of a flexible waterproof material.
