How to distinguish between building waterproof materials, home decoration waterproof materials, and engineering waterproof materials? Different building parts have different requirements for waterproof materials. Each material has its own advantages and disadvantages. There is no material that can be used for everything. Various materials can only complement each other, but not replace each other. They each have their own uses. The requirements for materials for roof waterproofing and basement waterproofing are different, and the waterproofing of bathrooms and walls is even more different. Sloped roofs, roofs with complex shapes, and metal plate base roofs are also different. Careful consideration should be given when selecting materials.
How to distinguish between building waterproof materials, home waterproof materials, and engineering waterproof materials? Different building parts have different requirements for waterproof materials. Each material has its own advantages and disadvantages. One material cannot do everything. There is no material that is good for everything. Various materials can only complement each other, but not replace each other. Each has its own use.Roof waterproofing and basement waterproofing have different material requirements, while bathroom waterproofing and wall waterproofing are even more different. Sloped roofs, complex-shaped roofs, and metal plate base roofs are also different, and careful consideration should be given when selecting materials.
1. Which waterproof material should be selected for roof waterproofing?
The roof waterproof layer is exposed to nature, subjected to the scorching sun, strong winds, rain and snow erosion, and the torment of extreme temperatures and the changes in temperature difference between day and night. Without excellent material properties and good protective measures, it is difficult to achieve the required service life. Therefore, waterproof materials with high tensile strength, large elongation, and good aging resistance should be selected.
2. Why do walls leak, and what waterproof material should be used?
This is because the current walls are too thin, mostly made of lightweight masonry blocks, with many internal and external joints, and the joints between the door and window frames and the walls are not sealed tightly, allowing rainwater to seep in through the cracks. Waterproofing of walls cannot use rolls, only coatings, and they must be combined with exterior decoration materials.
3. How to select materials for underground building waterproofing?
The underground waterproof layer is immersed in water or very humid soil for many years, so the waterproof material must have good water resistance. Rolls made of easily rotted substrates cannot be used. The bottom plate waterproof layer should use thick and puncture-resistant waterproof materials. It is recommended to use multiple layers with a total thickness of 6mm~8mm.
4. The waterproofing of kitchens and bathrooms has three characteristics. How to choose suitable waterproof materials?
First, it is not affected by natural climate, the temperature change is small, and the elongation of the material is not required;
Second, the area is small, there are many yin and yang corners, and many pipes pass through the floor slabs;
Third, tiles are pasted on the wall waterproof layer, and the affinity with the adhesive is good.
Based on the above three characteristics, rolls cannot be used, and only coatings are the most suitable.
5. Material selection for waterproofing of landfills, lakes, ponds, ditches, and planted roofs
Mainly using Jiashi Duo K11 general-purpose waterproof coating and super-elastic self-closing waterproof slurry, which are non-toxic, environmentally friendly, pollution-free, and truly environmentally friendly materials. The construction is quite convenient and can be directly brushed or scraped on the concrete surface.
6. More and more overpasses are being built in urban construction. The reinforced concrete beams and slabs must be waterproof to extend their service life. Because high-temperature asphalt concrete pavement is laid on the waterproof layer, the waterproof layer should be resistant to high temperatures of 110℃.
7. The waterproofing technology of caverns is complex, including rock caverns and loess caverns. In rock caverns, there are two types of lining: detached and attached.
For attached lining in rock caverns, after spraying concrete, a cement mortar leveling layer is applied to its surface, and then SBS modified asphalt membrane is applied. Polyester waterproof membrane can also be used. For detached lining in rock caverns, waterproof coatings, polyurethane coatings, or chloroprene latex asphalt coatings are sprayed on the surface of the sprayed concrete. Loess caverns are mostly masonry lined, with internal waterproofing. Polymer waterproof mortar is applied or acrylic ester coating is brushed on the cement mortar surface.

Why are the tiles falling off even though the tile adhesive doesn't contain cement?
Adding cement to tile adhesive will affect its bonding strength. Many people ask why tiles still fall off even without adding cement. What's the problem?
How to choose the right tile adhesive?
Tile adhesive, as the name suggests, is a special glue used to paste tiles. Commonly, when laying floor tiles and ceramic wall tiles, we may use cement products. Although cement is inexpensive and readily available, its bonding ability is not very prominent. This specialized tile adhesive is different; it is lighter in color, does not affect the aesthetic effect, and is waterproof, moisture-proof, and corrosion-resistant. Whether installed in the bathroom or kitchen, satisfactory results can be achieved. The following is a recommendation of the characteristics of Xiangshan Tiecheng tile adhesive and precautions during the purchase process for your comprehensive understanding and analysis.

For waterproofing and leak prevention, use Xiangshan Tiecheng "Leak Stopper"
Why use Xiangshan Tiecheng "Leak Stopper"? I believe that encountering water leaks must be very frustrating. There are many reasons for roof leaks. For example, the installation of waterproof materials did not consider drainage issues; secondly, before applying waterproof coatings, the base layer was not treated as required, resulting in gaps in the waterproof layer; or the entire area was not fully brushed during construction, and some yin and yang corners and pipe root parts were not covered with mesh, resulting in gaps; finally, it is related to the quality of the waterproof materials selected. What are the causes of bathroom leaks?
Why use back glue when tiling?
As an important building material in decoration, tile laying has become one of the important links in home decoration. If tiles are not firmly attached, it will not only affect the appearance, but also create safety hazards. So how to make the tiles adhere more firmly and effectively avoid the problem of tile falling off? Tile back glue comes into being.
