Manager Zang from Dalian Drainage Board: 133.4529.3123. What quota should be used for the landscape engineering Henkel concave-convex drainage board for roof gardens and green planting areas? How should it be priced? The waterproof construction process for the underground garage base plate using Taian Henkel drainage board is as follows: 1. **Base Plate Cleaning**: Before construction, the garage base plate should be thoroughly cleaned, and the construction surface must be flat and solid, without any sand, sharp protrusions, hollow spots, or pits. 2. **Laying the Membrane**: The membrane should be laid on the structural base plate in a specific overlapping order from front to back and side to side. 3. **Overlap Columns**: Small overlap columns should be inserted into larger overlap columns at the front, back, and sides of the membrane. 4. **Preventing Leakage**: To prevent leakage during construction or sliding of the membrane, glue can be applied along the overlap edges or cement can be poured at certain intervals to fix the membrane down. 5. **Pouring**: 1. Use C20 fine stone concrete to pour over the membrane, leveling it with a straight rod, ensuring it is 1-2 cm higher than the membrane and allowing it to harden before proceeding with subsequent construction. 2. After the concrete sets, reinforce with steel bars and pour the concrete surface layer, setting up drainage ditches and collection wells within the base plate. 6. **Precautions**: 1. The membrane must be completely overlapped and fixed to prevent slurry leakage. 2. Soft-soled or nail-free shoes should be worn during installation to prevent puncturing the membrane. 3. Heavy vehicles must not be driven directly on the membrane to avoid crushing or breaking the material. 4. Fire safety precautions should be taken for materials. 7. **Design Specifications**: For detailed construction plans and node diagrams, please refer to the national standards for "Underground Engineering Construction," "Flat Roof Construction II," "Residential Building Construction," and "General Construction Drawing Collection." **Application Scope of Drainage Board**: - **Landscape Engineering**: Garage rooftop greening, rooftop gardens, vertical greening, sloped roof greening, football fields, golf courses. - **Municipal Engineering**: Airports, roadbeds, subways, tunnels, landfills. - **Construction Engineering**: Upper or lower layers of building foundations, interior and exterior walls and base plates of basements, waterproofing and thermal insulation layers on roofs. - **Hydraulic Engineering**: Waterproofing for reservoirs, water retention basins, and artificial lakes. - **Traffic Engineering**: Road and railway embankments, dikes, and slope protection layers. **Introduction to Henkel Roof Beautification Drainage Board**: The roof beautification drainage board produced by Henkel is known for its quality and affordability, widely used in various waterproofing and drainage projects across the country. The product is characterized by high hardness and strong flexibility. The construction specifications for the roof beautification drainage board are based on the "Construction Technical Specifications for Highway Subgrade" (JTG F10-2006), "Quality Inspection and Appraisal Specifications for Highway Engineering" (JTG F80-2004), and the interpretation manual for the same. The roof beautification drainage board is suitable for soft foundation sections with a thickness greater than 4 meters, typically using plastic drainage boards for treatment. The construction of the roof beautification drainage board must adhere to regulations, and specific construction issues can be consulted with the Henkel roof beautification drainage board manufacturer. We produce and sell more professional products. The construction preparation for the roof beautification drainage board includes reviewing the construction drawings for the garage drainage board, clarifying relevant technical issues, familiarizing oneself with standards and technical specifications, and determining the route, boundary lines, centerline, and elevation control points using approved benchmark points and control lines. **Construction Methods for Drainage Board**: 1. Clean the construction site from debris, level with cement, ensuring there are no obvious bumps or dips. The outdoor garage top and rooftop garden should have a slope of 2-5‰. 2. Rooftop greening and outdoor garage top greening can be used with multi-hole drainage pipes to concentrate the water drained from the drainage board into nearby sewer pipes or city drainage systems. 3. For waterproofing the basement floor, a drainage board is installed above the foundation before the floor is laid, with the domed side facing down and blind ditches left around the perimeter, allowing underground water to flow naturally through the drainage board’s space into the surrounding blind ditches, then into the collection pit. The drainage board is a new green product from our company, applicable in urban greening, real estate greening, building foundations, tunnels, bridges, highways, railway systems, rooftop drainage and insulation, garage tops, landscaping projects, and rooftop garden greening.
