Shenyang Drainage Board Manager Zang: 133.4529.3123. For landscape engineering, what quota should be used for Hanco's concave-convex drainage storage boards? When constructing a landscape garden on the roof and laying concave-convex drainage storage boards in the greening planting area, what quota should be used and how should it be priced? The waterproof construction process for Taian Hanco drainage boards in underground garage floor: 1. **Floor Cleaning**: Before construction, the garage floor must be thoroughly cleaned. The construction base must be flat and solid, without phenomena such as sand, sharp protrusions, hollow areas, or depressions. 2. **Laying**: 1. Lay the membrane on the structural floor in a specific overlapping order. 2. There are large and small overlapping pillars among the membranes that should be fitted together. 3. To prevent leakage or sliding during construction, glue may be applied at the overlapping edges, or cement points can be poured at intervals to fix them. 3. **Pouring**: 1. Pour C20 fine stone concrete on the membrane, leveling it with a straight rod, with a height of 1-2cm above the membrane, and allow it to harden before proceeding with subsequent construction. 2. After the concrete has set, rebar should be tied, and a concrete surface layer poured, with drainage ditches and sumps set in the floor. 4. **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 avoid puncturing the membrane. 3. Heavy vehicles should not drive directly on the membrane to prevent crushing or damaging the material. 4. Fire protection must be considered for the materials. 5. **Design Specifications**: For detailed construction plans and node diagrams, please refer to the national standards "Underground Engineering Construction Structures", "Flat Roof Construction Structures II", "Residential Construction Structures", "General Construction Atlas". **Application Scope of Drainage Boards**: - **Landscape Engineering**: Garage roof greening, rooftop gardens, vertical greening, sloped roof greening, soccer fields, golf courses. - **Municipal Engineering**: Airports, roadbeds, subways, tunnels, landfills. - **Building Engineering**: Superstructures or substructures of buildings, exterior and interior walls and floors of basements, waterproofing and insulation layers of roofs. - **Water Conservancy Engineering**: Reservoir waterproofing, water storage pools, artificial lakes waterproofing. - **Transportation Engineering**: Highway, railway roadbeds, embankments, and slope protection layers. **Introduction to Hanco Roof Beautification Drainage Boards**: Hanco’s roof beautification drainage boards are known for high quality and low cost, widely used in various waterproof drainage projects across the country. The product is characterized by high hardness and strong flexibility. The construction technology specifications for roof beautification drainage boards are based on "Construction Technical Specifications for Highway Roadbeds" (JTG F10-2006), "Quality Inspection and Identification Specifications for Highway Engineering" (JTG F80-2004), and the explanatory manual for "Construction Technical Specifications for Highway Roadbeds" (JTG F10-2006). The roof beautification drainage boards are applicable in soft foundation sections with a soft soil thickness greater than 4 meters, typically treated with plastic drainage boards. Construction must follow regulations, and for specific construction queries, you can consult the Hanco roof beautification drainage board manufacturer. We produce and sell more professional products. The disclosure content for roof beautification drainage boards includes: construction preparation, reviewing the garage drainage board construction drawings, clarifying relevant technical issues, familiarizing with standards and technical specifications, and using approved benchmark points to determine route edge lines, center lines, and elevation control points. **Drainage Board Construction Methods**: 1. Clean up the construction site, level with cement, ensuring no obvious unevenness. The outdoor garage roof and rooftop garden require a slope of 2-5‰. 2. Rooftop greening and outdoor garage roof greening can use porous drainage pipes to concentrate the water drained from the drainage board into nearby sewer pipes or municipal sewers. 3. For basement floor waterproofing, a layer of drainage board should be placed on top of the foundation before constructing the floor, with the rounded protrusion facing down and leaving blind ditches around, preventing groundwater from rising. The seepage water naturally flows through the spaces of the drainage board into the surrounding blind ditches and then into the sump. The drainage board is a new greening product from our company, applied in urban greening, real estate greening, building foundations, tunnels and bridges, highways and railways, roof drainage and insulation, garage roofs, landscape engineering, and rooftop garden greening.
