Self-adhesive waterproofing membrane test how much the size of a unit it? 1, with the same species, the same grade, the same level of product per 10,000 square meters in one batch by batch count also insufficient. 2, in each batch of products, drawn 5 volumes sample, visual inspection. After that, put the number of the lightest volume roll out, do other physical performance tests. 3, in this volume examine the physical properties of membrane tested, Heihe self-adhesive waterproofing membrane, before remove 2.5 meters, then along the longitudinal length of the full width web interception of 800mm 2, one at the top for sample cutting, self-adhesive waterproofing membrane specification, the other backup. Self-adhesive waterproofing membrane common problems and treatment measures 1, bubbles, hollowing: Due to wet grass, leveling layer is dry, the moisture content is too large, the coating void, forming bubble. Approach: first of all cut off from the drum section, exposing the grassroots, self-adhesive waterproofing membrane procurement, discharge of moisture, to be dried grass, then in accordance with the construction method waterproof layer repair. 2, broken: waterproof layer construction, the former curing, no attention to the protection, construction and other processes being damaged, scratched. For severe cases, damaged, damaged part should be cut off (slightly larger), exposing the grass and clean up, and then follow the construction requirements of the order, layered up waterproof layer.
