The invention relates to the field of building waterproof
engineering, and discloses a composite waterproof material construction preparation process which comprises the following steps: S1, cleaning and treating a base surface to ensure that the base surface is dry and flat; s2, mixing the capillary crystalline waterproof
coating with the
cement mortar in proportion; s3, uniformly
coating a base surface with the mixed capillary crystalline waterproof
coating and
cement mortar; s4, immediately paving a wet paving waterproof coiled material on the coated base surface; s5, the laid waterproof coiled material is compacted, and it is ensured that the waterproof coiled material is completely attached to the
base plane; s6, seams and detail positions of the coiled material are sealed; and S7, initial maintenance is conducted. According to the method, the waterproof construction steps are simplified, the working procedures of
multiple stages are integrated, for example, laying of the waterproof coating and laying of the coiled material are completed in
continuous operation, and the construction time is effectively shortened. In addition, the accurate metering and mixing method is used, so that the preparation time of the materials is shortened, and the overall construction speed and efficiency are improved.
