Drainage boards, combined with porous drainage pipes, form an effective drainage system. Replacing the gravel filter layer with drainage boards for drainage saves time, effort, and energy, reduces investment, and also lowers the load on the building. A good drainage system plays a crucial role in the construction period of civil engineering projects and the normal use and lifespan of structures.
Prior to the flooring work, a drainage board is installed with its convex platforms facing down, surrounded by blind channels to prevent groundwater from rising. The infiltrated water naturally flows through the spaces in the drainage board into the surrounding blind channels, and then into the collection pit. The plastic drainage boards are available in two series: rolls and sheets. Special technology is used to press the plastic sheets into closed, convex columnar shells, creating a wavy membrane with continuous shells and a certain height of support. During the manufacturing process, butyl rubber strips are heat-sealed to the edges. The top of the shell is covered with a geotextile filter layer, which is used for infiltrating, draining, and storing water.
Also known as: Lapped Adhesive Drainage Mat, Drainage Board, Drainage Protection Board, Filter Plate, Plastic Grooved Drainage Board, Plastic Sandwich Panel. The cylindrical, multi-hole drainage board, in conjunction with geotextile, forms a drainage system, thereby creating a system with functions of seepage, storage, and drainage. Waterproofing for basement floors.
Above the ground level, the product specifications are divided into square greenery and basement use, with H20 and H25 options available. The top of the conical pedestal is bonded with a layer of filtration geotextile to prevent soil particles from passing through, thereby avoiding blockage of the drainage channels and ensuring smooth water drainage. Traditional drainage methods use bricks, tiles, and blocks as the filter layer, with a large amount of cobblestones or gravel as the water filter layer, and drain the water to the designated location.
