Liaoning Drainage Board Manager Zang: 133.4529.3123. What quota should be used for the Ecological Engineering Henkel concave-convex drainage board? For rooftop gardens, the concave-convex drainage board is laid in the green planting area. What quota should be used for this, and how is it priced? Taian Henkel drainage board waterproof construction process for underground garage floor: 1. Floor cleaning: Before construction, the garage floor should be cleaned, and the construction base must be flat and solid, with no signs of sand, sharp protrusions, hollow spots, or pits. 2. The rolls should be laid on the structural floor in a specific sequence, overlapping each other. 3. At the overlaps, there are large and small overlap columns, and the small overlap column should be inserted into the large overlap column. 4. To prevent leakage or sliding during construction, glue should be applied at the overlap edges, or cement points should be used at certain distances to fix them. 3. Pouring: 1. Use C20 fine stone concrete to pour over the rolled materials, leveling it with a straight rod, raised by 1-2 cm, and wait for it to harden before proceeding with subsequent construction. 2. After the concrete sets, rebar should be tied, and a concrete surface layer poured, with drainage ditches and water collection wells set in the floor. 4. Precautions: 1. The rolls must be laid completely and fixed to prevent slurry leakage. 2. Soft-soled or nail-free shoes should be worn during laying to prevent puncturing the rolls. 3. Avoid driving heavy vehicles directly on the rolls to prevent materials from being crushed or broken. 4. Pay attention to fire safety for materials. 5. Design specifications: For detailed construction plans and node diagrams, please refer to the national atlas "Underground Engineering Construction," "Flat Roof Construction II," "Residential Building Construction," and "General Construction Atlas." Application range of drainage boards: - Green projects: Garage roof greening, rooftop gardens, vertical greening, sloped roof greening, football fields, golf courses. - Municipal engineering: Airports, roadbed, subways, tunnels, landfills. - Building engineering: Upper or lower layers of building foundations, walls, and floors inside and outside basements, waterproofing and thermal insulation layers on roofs. - Hydraulic engineering: Reservoir waterproofing, water storage tanks, artificial lake waterproofing. - Transportation engineering: Road and railway embankments, levees, and slope protection layers. Introduction to Henkel's rooftop beautification drainage board skills: Henkel's rooftop beautification drainage board is known for its quality and affordability, widely used in various waterproofing and drainage projects across the country. The hardness and flexibility of the rooftop beautification drainage board are noteworthy. The construction skills for this product are based on the "Technical Specifications for Roadbed Construction" (JTG F10-2006), "Quality Inspection and Appraisal Specifications for Highway Engineering" (JTG F80-2004), and the interpretation manual of the "Technical Specifications for Roadbed Construction" (JTG F10-2006). The rooftop beautification drainage board is suitable for soft foundation sections with soil thickness greater than 4 meters. Generally, plastic drainage boards are used for treatment. The construction of rooftop beautification drainage boards should be carried out according to regulations. For specific construction issues, you can consult the manufacturers of Henkel rooftop beautification drainage boards; we produce and sell more professionally. The content of the rooftop beautification drainage board disclosure includes construction preparation, reviewing the drainage board construction drawings for the garage, clarifying relevant technical issues, familiarizing with standards and technical regulations, and using approved benchmark points and control points to establish route boundaries, center lines, and elevation control points. Construction methods for drainage boards: 1. Clean up debris at the laying site, level with cement, ensuring there are no obvious uneven areas. The outdoor garage roof and rooftop garden should have a slope of 2-5‰. 2. Rooftop greening and outdoor garage roof greening can be used with perforated drainage pipes to concentrate the water drained from the drainage board into nearby sewer pipes or municipal sewers. 3. For waterproofing the basement floor, a drainage board should be placed on top of the foundation, forming a layer of drainage board before the flooring is done. The convex side should face downwards, leaving blind ditches around to prevent groundwater from coming up. The seepage water will naturally flow through the space of the drainage board into the surrounding blind ditches and then into the collection pit through the blind ditches. The drainage board is a new type of greening product developed by our company, applied in urban greening, real estate greening, building foundations, tunnel bridges, highways and railways, rooftop drainage and thermal insulation, garage roofs, landscaping projects, and rooftop garden greening.
