How to prevent moisture and seepage in the basement home theater
With the improvement of the quality of life, in recent years, a large number of villa basements have been used to transform home theaters (audio studios), which have become a trend and fashion because they are basically not disturbed by external noise and the basement characteristics of their own music. However, moisture-proof and waterproof is a big problem, especially in Guangdong, Jiangsu, Zhejiang, Shanghai and some coastal areas. Due to the high groundwater level, the soil is damp and the developers have not constructed according to the waterproof technical specifications of the building, many basement walls, ground seepage and pan The tide has caused the deformation of the decorative products in the home theater, the mildew of the equipment, and the deterioration of the sound quality, which has made the potential home theater fans discouraged, and everyone has been unable to exert their fists. In response to these problems, Home Theater Network () shared with the majority of home theater enthusiasts how to do the basement theater moisture-proof and seepage prevention construction (hereinafter referred to as waterproof). The basement is divided into a full basement, a semi-basement, a semi-basement means that the basement is higher than the outdoor ground, and the full basement means that the basement is lower than the outdoor ground. According to the waterproofing requirements of the basement, the civil works should be waterproofed on the outside of the basement wall and the bottom of the basement. It is called “active waterproof†and waterproof inside the room. It is called “passive waterproofâ€. Passive waterproofing is a remedy. The construction is difficult, the technical requirements of the operation are high, and it is difficult to achieve the waterproof requirement. Do a good job of waterproofing the basement, summed up two sentences: 1. Complete the work of drilling and punching in advance; 2. Do the following three steps carefully. The waterproof construction of the basement consists of three steps: pre-construction preparation, waterproof construction, and post-construction protection. Each step is related to the waterproof effect. The most important work is to complete the drilling and hole drilling work ahead of schedule. Many underground listening rooms have been passively waterproof, but the effect is still not good. This is mainly because the construction points are not mastered, the operation is not careful, and the subtle decision is always the truth! If you can strictly follow the following methods, it is moisture-proof and anti-seepage. The effect is exact! First, preparation before construction: First according to design requirements 1. Slot the wall and ground wire. Pay attention to: slot the ground as much as possible, and make a private theater (home theater, audio-visual room, listening room, recording studio, HiFi room) with sound-absorbing wall structure. Take the tube. 2, in the wall, roof, ground embedded fixtures, such as curtain hooks, projector hangers, speaker connectors, keel (light steel keel, wood keel) fixed angle steel (can be folded into a right angle with 3mm galvanized sheet 100*50 ), line pipe cards, etc., after that, the è¡™ fixing parts are connected together, and no holes should be opened on the wall or the ground. 3. Repair the wire trough with high-grade cement mortar. be careful: v The line tube should be fixed firmly and not loose. The line tube has joints to be glued with glue, and the line tube should be 10mm out of the wall. v The embedded parts are in the correct position and are not loose. v Walls, roofs, and floors have empty drums to be re-painted. Second, waterproof construction: Before the waterproof construction, the wall, roof and ground concealed works are qualified and accepted, and the pre-embedded parts are qualified. The repair of the line trough can not be smoothed, and the wall, roof and ground surface are cleaned. Use environmentally-friendly high-quality waterproof sand paddles (two-component, available in Shanghai area, Chaoyang brand, Oriental Yuhong brand, local selection of high-quality products available locally), proportioned with sufficient mixing (mixing in batches to avoid long-term mortar change) Hard) Use scraper batch, order top-wall-ground, one square meter per kilogram, fully dry after 24-48 hours, and then batch again. be careful: v The waterproof mortar layer should be evenly thick and about 2mm. It should not be exposed to the base layer and hollow drum. The corner of the corner should be smeared into a pure angle. v There must be no gaps around the embedded parts. The perimeter of the v-line nozzle should be dense and waterproof and moisture-proof measures should be taken. Third, post-construction protection: After the waterproof sand pad is fully dried, it can be used for subsequent construction. It can be protected on the ground with a thickness of 5-9mm MDF. (If the height is high, the construction period can be 50mm C20 fine stone concrete protection on the ground waterproof layer. It takes a long time to maintain. ), can walk, do the floating floor structure should be fully dry after the ground waterproof layer, directly on the above auxiliary sound insulation felt plus 50mm C20 fine stone concrete, the top and wall surface installation should not damage the waterproof layer. Points to note: It must be strictly checked at the construction site. Workers in the construction work must bear in mind that it is more important to protect the waterproof layer than to make a waterproof layer! The private theater at this time is like a submarine submarine, and it is in vain to puncture the boat wall! The consequences are unimaginable! Fourth, other: The above waterproof construction is to prevent the water outside the building from seeping into the room and flooding. The basement is also protected from moisture. During the rainy season, the air humidity is high. At this time, the walls on the second and third floors will be wet, and the basement will be more serious. Can not be solved by construction methods, the simplest method, close the basement door, use the dehumidifier to work 24 hours!
