3 thoughts on “Waterproof construction process”

  1. The waterproof construction process of the bathroom is as follows:
    1. Before construction, ensure that the base surface is clean and dry. The first coating waterproof coating. Make sure that the coating is full and not leaky, and it can be closely combined with the grassroots level. There will be no cracks, foaming, falling off, and the thickness and height of the thickness.
    2. Apply waterproof coating for the second time. In actual operation, it should be separated from the first time to ensure that the first layer is completely dry, and it should be implemented after the coating is completely dry. The specific time should be judged according to the actual situation. Time is too short, and the waterproof effect cannot be guaranteed.
    This waterproof measures:
    It best to find water leakage points. During the inspection, the problem of the water pipe is some defects in the waterproof layer or in the construction, such as the key water leakage parts are not done well; whether the thickness and height of the waterproof layer are in place; whether the transformation of the pipeline in the later period has destroyed the waterproof layer, or the poor durability used used in the material appears. Cracks and so on.
    After finding the leak point, remedy according to the corresponding problems. If there is a problem with the pipeline, the pipeline should be replaced in time; if the waterproof layer is not in place, it is necessary to repair the waterproof layer. You can choose a brick seam supplement or reisting the waterproof layer with coating products.

  2. I. Construction process
    The waterproof material enrollment retest -technical intercourse -clean up the grassroots -binding layer -detailed additional layer -waterproof layer -test water test.

    . The construction of waterproof concrete
    (1), waterproof concrete must be accurate in accuracy in accordance with the coordination ratio. When the mixing compound appears separately, it must be used for secondary stirring. When the collapse is lost, the construction requirements cannot be met, and the cement slurry or secondary water reduction agent should be added with the raw water glue ratio.


    (2), the waterproof concrete should be made of high -frequency mechanical stratification, and the vibration time should be 10 ~ 30s. When a dense concrete is adopted, no mechanical tinkery can be performed.

    (3), waterproof concrete should be poured continuously, leaving less construction seams. When the construction seam is left, it is advisable to be kept on a small area and easy to build. The level of wall level construction should stay on a wall that is not less than 300mm above the surface of the floor.

    (4) The maintenance of waterproof concrete should be performed immediately after the condensation of the concrete, and the maintenance time should not be less than 14D.

    (5), when the waterproof concrete is under construction during winter, the molding temperature should not be lower than 5 ° C.

    . The construction of waterproof cement mortar
    1, the surface of the grassroots should be flat, solid, clean, and fully moist, without water.

    2, the waterproof mortar should be constructed with pressure method, and it is divided into survival. Each layer should be closely combined, and each layer should be continuously constructed. When you need to stay, the position of the upper and lower layers should be staggered by more than 100mm, and you must not leave the puppet within 200mm from the corner?

    3, the temperature of the waterproof mortar construction environment should not be lower than 5 ° C. After the final condensation, the maintenance temperature should not be less than 5 ° C, and the maintenance time should not be less than 14D.


    4. When the polymer’s cement waterproof mortar does not reach hardening, it shall not be watered or washed directly by water. The humid environment can be maintained under natural conditions.

    . The construction of the waterproof layer of coating film
    1, the grassroots should be flat and firm, and there must be defects such as holes, honeycomb hemp, and gaps on the surface; It should meet the product requirements.

    2, construction environment temperature: water milk -type coatings should be 5 ~ 35 ° C.

    3, the coating should first strengthen or seal the yin and yang angle, embedded parts, wall (floor) tube and other parts.

    4, the waterproof layer of the coating film should be survived multiple times, and the coating construction should be carried out before the coating before the coating. The direction of the painting two times should be perpendicular to each other. The facade should be painted first, and then the plane is brushed.

    5. When paving the material enhancement material, the waterproof coatings should be fully soaked, and the tires should not be exposed and folds. The long side of the carcass material should not be less than 500mm, and the width of the short side overlap should not be less than 700mm.

    6. After the waterproof layer is completed, the protective layer shall be made in time.

    . The construction of the waterproof layer of the coil
    1, the grassroots should be flat and firm, and there must be defects such as holes, honeycomb hemp, and gaps on the surface; It should meet the product requirements. The base layer of cement -based adhesives should be fully moist, but there must be no bright water.

    2, the construction environment temperature of the coil paving: The construction of the cold sticky method should not be lower than 5 ° C, and the hot melt method should not be lower than -10 ° C. Technical measures should be taken lower than the requirements requirements:

    3. Waterproof coils constructed by paste method should be paved with a full sticky method with the grassroots.

    4, the minimum overlap width of various coils should meet the requirements of the table below.


    5, the coil joints must be pasted tightly. Sealing treatment should be performed. The seal width should not be less than 10mm, and the position of the seams should be greater than 300mm from the yin and yang angle.

    6. The construction of waterproof coils should be paved first, and the back plane. After the construction of the waterproof layer is completed and accepted, the construction of other levels can be performed.
