Sheet – type drainage board
Short Description:
Sheet – type drainage board is a kind of geosynthetic material used for drainage. It is usually made of plastic, rubber or other polymer materials and is in a sheet – like structure. Its surface has special textures or protrusions to form drainage channels, which can effectively guide water from one area to another. It is often used in the drainage systems of construction, municipal, garden and other engineering fields.
It is generally made of polymer materials such as plastic and rubber, with raised or sunken lines on its surface to form drainage channels. These lines can be in the shape of regular squares, columns, or other shapes, which can effectively guide the water flow. Meanwhile, it increases the contact area between the drainage board and the surrounding medium, improving the drainage efficiency. In addition, the edges of the sheet - type drainage board are usually designed with structures that are easy to connect, such as card slots or buckles, which are convenient for connection during construction to form a large - area drainage system.
Performance advantages
Good drainage effect: It has multiple drainage channels, which can evenly collect and discharge water, allowing the water flow to pass through the drainage board quickly and reducing the phenomenon of waterlogging.
Flexible laying: With relatively small dimensions, it can be flexibly spliced and laid according to the shape, size, and specific requirements of the construction site. It is especially suitable for some areas with irregular shapes or small areas, such as the corners of buildings and small gardens.
High compressive strength: Although it is in the form of a sheet, through reasonable material selection and structural design, it can bear a certain amount of pressure and is not easy to deform during use, ensuring the stability and reliability of the drainage system.
Corrosion - resistant and aging - resistant: The polymer materials used have good corrosion - resistant and aging - resistant properties, which can be used for a long time under different environmental conditions and are not easily affected by chemical substances, water, ultraviolet rays, and other factors in the soil, with a long service life.
Application fields
Construction engineering: It is often used in the drainage systems of basements, roof gardens, parking lots, and other parts of buildings. In basements, it can prevent groundwater from penetrating into the interior, protecting the structural safety of the building. In roof gardens, it can effectively drain excess water, avoid waterlogging at the roots of plants, which may lead to rotting, and provide a good growth environment for plants.
Municipal engineering: It can be applied to the drainage of road subgrades, squares, sidewalks, and other places. In road construction, it helps to drain the water in the subgrade, improve the stability and strength of the subgrade, and prolong the service life of the road. In squares and sidewalks, it can quickly drain rainwater, reduce ground waterlogging, and facilitate the passage of pedestrians.
Landscape engineering: It is suitable for the drainage of flower beds, flower pools, green spaces, and other landscapes. It can maintain the appropriate humidity of the soil, promote the growth of plants, and prevent landscape damage caused by waterlogging.
