You are not unfamiliar with waterproof tarpaulins. There are many places where waterproof tarpaulins need to be used. Even our lives are inseparable from waterproof tarpaulins. Umbrellas are actually made of waterproof tarpaulin material. Today, tarpaulin manufacturers bring you the method of making water reservoirs with waterproof tarpaulins. 1. After the basic treatment meets the requirements, on the leveling layer, scrape and apply PA-A type high-molecular-weight cement slurry with a thickness of about 1-1.5mm as the interface layer, and the water-cement ratio = 0.4:1 (weight ratio). 2. The scratching direction of the second waterproof layer of the waterproof tarpaulin reservoir should be perpendicular to the first layer, the plastering should be compact, the thickness is about 2-3mm, and the water-cement ratio is 0.25-0.3:1 (weight ratio) The second layer Waterproof and directly tiled, saving money. 3. Before the initial setting of the bottom coating of the waterproof tarpaulin reservoir, you can scrape and apply a PA-C type Yijiao clay as the waterproof layer, the thickness is about 2~3mm, and the water-cement ratio is 0.25~0.3:1 (weight ratio). The construction of the second waterproof layer can only be carried out after the first waterproof layer is finally set. 4. If the pool is on the ground, apply a layer of PA-C type and PA-A type beneficial glue on the upstream surface and the backwater surface as a waterproof layer. 5. The construction of the waterproof layer should be at the bottom of the pool behind the wall, and the inner corner should be made into a circular arc. The waterproof tarpaulin requires the bottom of the pool to be scraped along the wall as a whole at one time, leaving no joints and no leakage. At the height of about 300-500mm on the wall, and higher than the original concrete construction joint, the waterproof layer at the bottom of the pool and the waterproof layer on the pool wall should intersect. 6. The use of high-molecular-weight cement as the waterproof and pasted facing tiles for pools can refer to the practice of toilets. 7. After the construction of the waterproof tarpaulin waterproof layer and the facing brick is completed, it needs to be cured at room temperature for 5-7 days, and no water shall be stored during the curing period.
