Some of our friends have a design basement downstairs. We know that the quality of the basement building is very strict, so our friends would like to know how to deal with the waterproofing of the underground outdoor wall. Our underground outdoor wall once leaking serious consequences, decoration home decoration small plait focus to introduce some of the basement wall waterproofing construction method, and the basement wall waterproofing considerations.
First, the basement introduction
1. The basement means that the height of the room floor below the outdoor ground level exceeds one-half of the net height of the room. Multi-storey and high-rise buildings require a deeper foundation. To use this height, building a basement under the building's ground floor can increase the use area and save the room backfill, which is relatively economical.
2. Building a basement below the ground floor of the building can improve the efficiency of the building land. Some high-rise building bases are deeply buried, making full use of this depth to build a basement, which is economically effective and effective. According to the function of the basement, there are common basement and venting basement; according to the structural materials, there are brick walls and concrete structure basement, which are divided into structures, with full basement and semi-basement.
Second, the underground outdoor wall waterproof construction steps
1. Pouring concrete: The underground outdoor wall formwork must be fastened with a one-time water stop screw. The underground outdoor wall is left with construction joints and post-casting belts as required. The construction joint or the post-casting belt shall be temporarily sealed with a steel mesh and the waterstop shall be provided as required. The template is left with a cleaning port, and the garbage in the wall is cleaned in time before the mold is closed. After the end of the curing, the disposable water stop screw was cut off in time, and the screw end was closed with polymer cement mortar.
2. Defect repair: The concrete exterior wall defects should be carefully repaired before the waterproof layer is constructed to ensure that the base layer meets the requirements of waterproof layer construction. For general defects and cracks, pores and general defects of concrete surface with a crack width of less than 0.2mm, first fill the flat with concrete repair glue, and then smooth and smooth after drying.
3. When the crack width exceeds 0.2mm, the buried pipe can be grooved on the concrete surface, and the concrete crack can be repaired by pressure grouting.
4. Waterproof additional layer: Before the waterproof construction, the base layer of the outer wall should be polished and leveled, and the repair of the defect is completed, and the screw groove has been treated flat. The waterproof additional layer shall be constructed as required in the construction of the external wall, the post-casting belt, the bottom plate and the external wall transfer, and the screw.
Third, the underground outdoor wall waterproofing precautions
1. When the basement waterproofing construction work, relevant operators should wear helmets.
2. The construction materials are flammable, and the materials storage and construction site must comply with the relevant national fire protection regulations.
3, the use of solvents such as xylene should be the corresponding anti-virus measures.
4. When working with waterproof construction personnel, do not wear waterproof layer on the shoes with nails, pay attention to the protection of finished products.
Through the knowledge of some construction steps for waterproofing our underground outdoor wall and the precautions for waterproofing the underground outdoor wall, our friends also know what the benefits of the basement are, then our decoration home network will also I will introduce other decoration information to you, and my friends hope to pay attention to it.

Catalog of IR LED.
We are IR LED manufacturer from China.
All of our product are meet with Reach, CE, RoSH, SGS, EN62471 standards.
IR LED(Infrared LED), normally, which is 850nm IR LED and 940nm IR LED.
You can see some weak red bright when the 850nm IR LED is working, But you can see nothing when the 940nm IR LED is working. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.
IR LED widely used for those "night-vision" cameras, IP camera, remote controls, Touch screen, intelligent monitoring, webcam, hunting camera, CCTV cameras, surveillance cameras and security system. For instance, 940mn Through-hole IR LED did a great job in night-vision. 850mn SMD IR LED did a great job in infrared touch screen.
We use the best raw material, like Taiwan's Epistar chip, Tyntek chip, optocech chip and 99.99% gold wire for your best prouct, which is make our product have a fabulous performance. Looking forward to cooperate with you.
