Proper waterproofing of a basement should be tailored to the nature and requirements of the project. The chosen waterproofing standard must be reliable, the method should be simple to implement, and the materials used should offer good cost-effectiveness. The principle of waterproofing follows the concept of “prevention, drainage, protection, and blocking.†Below are recommended construction methods for applying waterproof materials in basements (note that these schemes must be completed before applying the protective layer, which can be a cement mortar layer with a thickness of 2–4 cm): First, a combination of rigid and flexible waterproofing (for surface waterproofing): apply a single-component penetrating crystalline material as the first layer, using approximately 0.9–1.2 kg per square meter. Once the first layer is dry (after at least 12 hours), apply a second layer using flexible waterproof slurry, with a similar coverage of 0.9–1.2 kg per square meter, adjusting slightly depending on the surface condition. The total thickness should reach at least 1.0 mm. If the building structure remains undistorted and the protective layer is intact, this system can provide waterproof performance for up to 25 years. Second, general-purpose waterproof slurry — single-component penetrating crystalline type (for surface waterproofing): apply two or three coats, ensuring each layer is fully dry (at least 12 hours) before applying the next. The total amount used per square meter should be approximately 1.8–2.5 kg, with slight variations depending on the base surface. The total thickness should be at least 1.2 mm. Under normal conditions where the building structure is stable and the protective layer remains undamaged, this method can provide effective waterproofing for at least 10 years. Third, a combined method using single- and two-component waterproof slurry (for surface waterproofing): apply a single-component penetrating crystalline material as the first layer, using about 0.9–1.2 kg per square meter. After it dries (more than 12 hours), apply a second layer using a two-component waterproof slurry, with a similar coverage of 0.9–1.2 kg per square meter, adjusting slightly based on the surface condition. The total thickness should reach at least 1.0 mm. This system can last up to 15 years if the building structure remains intact and the protective layer is not damaged. 4. Special areas such as阴阳 corners (yin-yang corners), Nozzles, and post-casting joints require additional attention. These areas should be coated with flexible waterproof slurry at least twice, ensuring the total thickness exceeds 1.2 mm for enhanced protection. It's important to follow all instructions carefully during installation to ensure long-term effectiveness. Regular maintenance and inspections can also help extend the lifespan of the waterproofing system. Always consult with a professional if you're unsure about the best approach for your specific project. Laser Water Screen Film Fountain Show
