Waterproof casing is known to be very much used in the construction of curtain walls, and is a component that is pre-installed in concealed works. It is a component that is placed when the structure is poured, and can be used as a connection for post-process fixing. Generally, waterproof casing is processed according to the drawings, and then measured and positioned and bracketed.
Generally, the pipe length of the casing is two sizes larger than the pipe length of the water pipe to be traversed through the structure. The casing is generally 2-4 cm thicker than the pipe to be used and is fixed in the wall or slab, from which the pipe passes. The waterproof casing is sealed with steel material between the casing and the pipe to achieve the sealing effect. Flexible waterproof casing is in the middle of the casing and the pipe, with flexible materials to seal the effect of sealing. If the location of the crossing is not waterproof requirements, pre-buried is the general casing, if there are waterproof requirements, then waterproof casing.
