Self adhesive waterproof coiled material is not waterproof? What's the problem?

Self adhesive waterproof coiled material is a new type of waterproof material with great development prospect. It has low-temperature flexibility and self-healing. It can be constructed at room temperature with fast construction speed, and also meets the requirements of environmental protection. The waterproof coiled material has good low temperature resistance. It is the best waterproof and moisture-proof sealing material for subway, tunnel and non hot work site. It is also suitable for waterproof and anti-corrosion engineering of pipeline.

What is the root cause of the problem that waterproof materials are not waterproof? It may be that the construction method is wrong. During construction, the building materials may have excessive pores, strong water absorption, poor impermeability, etc. If you meet developers who want to save money, you may encounter this situation. Secondly, there are many external wall leakage problems. It may be that the frame structure is unstable, or the building wall is not prepared according to the standard; It may also be due to insufficient adhesion between wall tiles and base mortar, as well as various pipe perforation, windowsill slope and other problems. Another point is that self-adhesive waterproof coiled material cannot be paved on the frozen base surface. The base course with polluted and high moisture content can not be constructed. The above reasons are the most likely reasons for the non waterproof of self-adhesive waterproof coiled materials. We should pay more attention during construction to avoid such problems.

Therefore, the main problem that waterproof materials are not waterproof is that the building itself and manual construction do not pay more attention. Some people still leak water after repeated waterproof construction, indicating that the root cause of water leakage has not been found. Experienced construction workers will go to the leakage site for on-site observation to find out the cause of the leakage and find out the correct method. Only in this way can the problem be fundamentally solved. The above is a series of summary on the non waterproof problem of self-adhesive waterproof coiled material, hoping to be helpful to you.
