Problem 1: quality of waterproof materials
The so-called "high-quality waterproof materials" popular in the market at present, if tested according to national standards or industry standards, most of the widely used color steel tile waterproof materials are unqualified products. Nowadays, a large
number of fake and inferior products are prevalent in the building material market, which makes the real high-quality waterproof materials in the market less and less. Therefore, in terms of material selection, we must be cautious and cautious, and the
waterproof materials must select the standard products.
Problem 2: design does not pay attention to
The uncertainty of the designer in the design of the thickness of the waterproof layer makes the nature, importance and function of the waterproof
layer of the color steel plant do not match, which is difficult to meet the waterproof requirements of the workshop. Some design units design the waterproof and thermal insulation layer of the workshop roof completely unreasonable, resulting in the building
insulation layer leaving water and absorbing moisture in the air. Through the wind and sun, the local waterproof layer is arched. Repeated such a process, the waterproof layer will deform and accelerate aging due to the change of temperature and humidity,
which leads to the waterproof quality problems of the workshop.
Problem 3: the quality awareness of the construction unit is not strong
In the market, fake and shoddy products of color steel tile waterproof materials are rampant. Many construction
units directly use waterproof materials for construction without inspection, and the general contracting audit is not strict, so that the low-quality contracting team can undertake the construction. Many workers did not get the operation and knowledge
training before the construction, nor did they have the job certificate. Moreover, they lacked the understanding of the construction and acceptance standards of waterproof materials and waterproof engineering, and the quality control in the construction
process was not strict, resulting in poor construction quality.
Problem 4: the use and maintenance management is not in place
Because the color steel roof has been in the natural environment for a long time, the waterproof layer of color steel
sheet can not be kept intact for a long time. After the completion of the steel structure project, the management and maintenance after the delivery of the project is not in place, resulting in the leakage of color steel plate.
