Enterprise owners who live in the top floor know that the top floor waterproofing is a major project, and it is not handled properly. If it is rainy, it is their own home. In contrast, foreign owners seem a bit perfunctory. They lay bricks on the roof for waterproofing, and directly pour cement mortar and brush it. It’s simple, but will it really not leak?
Foreign houses like to lay red bricks on the roof, and waterproofing in the middle gap becomes the focus. If it is not handled properly, water will flow down the gap on rainy days, and water will accumulate over time. Logically speaking, this step is very important, but how do foreign owners do it?
Stir the cement mortar, then pour it directly on the red bricks, brush it evenly with tools to ensure that all the gaps in the bricks can be covered. The entire operation process is very simple, effortless and effortless.
When the cement mortar is completely penetrated, shovel all the cement on the surface, and finally clean it with a wet rag and it is finished. It seems that there is nothing wrong with it, but this treatment does not ensure that all gaps are filled. As the temperature changes, there are even thermal expansion and contraction. Some foreign owners are lazy and do not stir the cement mortar. They sprinkle cement ash on the roof and pour some water. It's really perfunctory, so don't learn it easily! Although this roof waterproofing method is strange, it is actually the same as waterproof grouting, but the material selection should be cautious. The most commonly used oily polyurethane grouting material in China. Use professional tools to pour it into the gaps or holes in the roof. It will penetrate the surroundings through the gaps, and eventually form a mesh structure, which will have a waterproof effect.
Foreign roof waterproofing method is simple and easy to operate, you can do it yourself and you can complete it in half a day. The final waterproofing effect may be fine in a short time, but it may be a bit disappointing in a long time. It is recommended to ask a professional master to solve it. This aspect is more reliable in China!
Compared with waterproof coating , waterproof coil is more popular because it not only has good water resistance, but also has stability for temperature changes in all seasons, making it very suitable for roof waterproof construction. In addition, it is recommended to choose self-adhesive construction. Fire-baked construction is more suitable for flat grounds, and it will also be affected by the weather and is prone to uneven heat. Self-adhesive construction has a wider range of applications. Even in corners, there can be no gaps left. Only by handling the details well can we ensure that there will be no water leakage in the later stage.
