Supply Drainage Boards for Rooftop Gardens in Liaoning / Liaoning HDPE Drainage Boards / Garage Drainage Boards

1. Clean up the construction site by removing debris and leveling the cement, ensuring that there are no obvious bumps or depressions. The outdoor garage roof and rooftop garden should have a slope of 2-5‰. 2. This will help concentrate the water drained from the drainage board into nearby sewer pipes or local city drainage systems. 3. For waterproofing the basement floor, a drainage board should be installed above the foundation, creating a layer before the flooring is laid. The round protruding surface should face downward, with blind ditches left around to prevent groundwater from rising. The seepage will naturally flow through the spaces of the drainage board into the surrounding blind ditches and then into the collection pit. 4. For waterproofing the inner walls of the basement, drainage boards can be laid on the main walls of the building, with the round protruding surface facing the main wall. A single wall or a layer of wire mesh plastered with cement can be built outside the drainage board to protect it, allowing the seepage from outside to flow directly down into the blind ditches and then into the collection pit. 5. When laying drainage boards in any area, it is essential to ensure that dirt, cement, yellow sand, and other debris do not enter the front space of the drainage board, ensuring clear drainage pathways. 6. Protective measures should be taken during the installation of drainage boards. Backfilling of soil should be done promptly on surfaces or outdoor garage areas after laying the drainage boards to prevent strong winds from disturbing the installation quality. Waterproofing in the basement and on inner walls should have protective layers applied quickly to prevent damage to the drainage boards from people or objects. 7. The backfill soil should be cohesive soil, and a layer of 3-5 cm of yellow sand should be laid on top of the geotextile, which is ideal for facilitating drainage through the geotextile. If the backfill soil consists of nutrient-rich or lightweight soil, there is no need to lay an additional layer of yellow sand, as this type of soil is already loose and allows for easy drainage. 8. When laying drainage boards, the edges should overlap by 1-2 points, or two base boards can be aligned, with the geotextile overlapping on top. As long as there is no dirt entering the drainage channels of the drainage boards, drainage should remain unobstructed.
