    At present, the waterproof leakage rate of buildings is very high. The cause of Yantai can be attributed to the two aspects of data and construction. The information is pretending to be inferior, and the building is the Jerry Building that we often say.
    Today, when talking about the thickness of waterproof coatings, we all know that the establishment of waterproof specifications is the total thickness of "two layers, at least to millimeters", thereby ensuring a good waterproof effect.
    So what is the relationship between waterproof layer and waterproof life thickness?
    Why do some waterproof properties persist for five, ten, twenty years, or even the same structure of life?
    In fact, life is closely related to the thickness of the waterproof layer. We know that the waterproof coating layer is continuous, waterproof and breathable. Even if it is an effective waterproof coating, it is very thin and is easily damaged by mechanical damage. It can accept a certain amount of displacement over time. Over time, other, the degradation of the waterproof coating is slow, so what kind of durability, waterproofness, what kind of life.
    Therefore, in addition to the closed water experiment, the thickness of the coating should be measured by professional testing equipment. The thickness measurement of the fault block is a part of the waterproof construction, a random one (on the upper part, after the recommended facade is not required to be repaired so much), the cutting size is ×, and the film thickness is measured with a vernier caliper and a thickness gauge.
    Passing off water and shower water can clarify whether our waterproof coating layer is continuous and can be integrated as a whole. Measuring thickness can explain to what extent our waterproof layer can reach and how long it can be used. However, it is not to say that thicker waterproof coatings, on the other hand, are not economical, on the other hand, the thickness is too large, and it is easy to cause cracking.
    Generally speaking, the first-level waterproof (year life), waterproof coating is not less than, the two-level waterproof (year life), waterproof coating is not less than.
