What is the difference between roof waterproofing and bathroom waterproofing

1. Inspect and accept the appearance, variety, specification, packaging, size and quantity of materials, and form corresponding acceptance records.

2. Check the quality certification documents of the materials and include them in the engineering and technical files.

3. After the material enters the site, the material inspection report shall be issued according to the specification.

4. When all the indicators of the physical properties of the material meet the standards, it is qualified; If an index does not meet the requirements of the standard, the index should be re-sampled in the tested product for re-inspection, and the re-test result meets the requirements of the standard, and the batch of materials will be judged to be qualified.

5. Waterproof material. There are three main categories: waterproofing membranes; 911 polyurethane waterproofing material; New polymer cementitious waterproofing material.

The last category is divided into general-purpose GS waterproofing materials and flexible JS waterproofing materials. Among them, the universal waterproof material is suitable for the waterproofing of the indoor floor and wall of the family.

As the name suggests, roof waterproofing is different from bathroom waterproofing, roof waterproofing is in the outermost layer, bathroom waterproofing is a hidden project, generally the roof is laid with linoleum (SPS), and the roof waterproofing is divided into three categories: rigid waterproofing, flexible waterproofing and self-waterproofing. There are also polyurethane brushes in the bathroom that do not leak water, but they are basically the same, but the roof waterproofing can be considered with cheap asphalt and tarpaulin.

The indoor needs to use environmentally friendly, harmless waterproof materials, such materials are expensive. Different materials are made differently, and that's the difference.

Roof waterproofing is outdoor waterproofing, and conditions such as exposure to the sun should be considered. Bathroom waterproofing materials can not be used for roof waterproofing, and the waterproof materials of the bathroom are afraid of cold and hot changes, and are also afraid of sun exposure. Workers know it.

Both asphalt and linoleum are cheap and are not afraid of hot and cold changes. If you have an air conditioning hole in your home, you should pay attention to the hole with a high inside orifice and a low outside outlet, so that rainwater will not enter the room. When installing a new window, it should be noted that the window has a horizontal waterproof groove, and the workers all know that the window must be installed in the waterproof groove, and the waterproof groove cannot be covered, so there is no waterproof barrier.

The workers all know it, but sometimes they pretend to be grandchildren, tell the truth, and when you find out the problem, they leave.

According to the relevant national regulations, roof waterproofing requires 2 or even more materials for composite construction, that is, it is necessary to make flexible waterproof materials first, such as membranes and coatings, and then make rigid materials, such as mortar and concrete. The higher the level of waterproofing, the higher the performance of the waterproofing material required, and at the same time, the more complex the construction process. The toilet can only be constructed by selecting a certain type of material.

Rigidity is the best, because the bathroom itself is small and stable, and rigidity can make tile pasting easier.

The roof is waterproof, generally not protected, and needs to be resistant to the sun and freezing. Compared to this, the indoor has a protective layer and the life span is much longer.
