Beijing garage roof drainage board丨Landscaping drainage board [**Manager Xue]< br/> When laying drainage boards, protective measures should be taken as much as possible. When laying drainage boards on the surface or in outdoor garages, backfilling should be done as soon as possible to prevent strong winds from disrupting the drainage boards and affecting the quality of the laying. To prevent the drainage board from being damaged by people or objects, the backfill soil is clayey soil, and it is ideal to spread a centimeter of yellow sand on top of the geotextile, which is beneficial to the water filtration of the geotextile. If the backfill soil is a kind of nutrient soil or light soil, there is no need. Then lay a layer of yellow sand. The soil itself is very loose and can easily filter water.
