Composite Drainage Board
1. Strong drainage (equivalent to one metre thick gravel drainage).
2. High tensile strength.
3. Reduce the chance of geotextile embedded in the drainage channel, maintain long-term stable drainage.
4. Long-term withstand high-pressure load (can withstand about 300kpa compression load).
5. Resistant to corrosion, acid and alkali, long service life.
6. Construction is convenient, shorten the construction period and reduce the cost.
Product description
Composite drainage board is a non-woven fabric base cloth after heat composite firmly bonded to the drainage board, so the non-woven fabric not only protects the drainage board is not exposed to avoid the drainage board by the sun and shorten the service life, but also stabilise the drainage board of the stability of the drainage characteristics of the infiltration of drainage, the non-woven fabric has good three-dimensional void structure, has a good permeability, can make the water permeable through the past but impermeable to the soil, to avoid the soil is constantly piled up to block the Drainage board affects its drainage performance.
The top surface of the conical protrusion is glued with a layer of filtering geotextile to prevent soil particles from passing through, thus avoiding the blockage of the drainage channel and making the aperture drain smoothly. The traditional drainage method uses masonry tiles as the filtering layer, more cobbles or gravel as the water filtering layer, and drains the water to the designated place. The use of drainage boards to replace the cobble filter layer to drain the water is time-saving, energy-saving and energy-saving, saving investment, but also reduces the load on the building.
Good drainage system has an important role in the construction cycle of civil engineering and the normal use and life of the building. Drainage board and porous water seepage pipe form an effective drainage system, cylindrical hollow drainage board and geotextile also form a drainage system, so as to form a system with seepage, water storage and drainage function.
Application
1. Landfill drainage.
2. Roadbed and road drainage.
3. Railway drainage, tunnel drainage, underground structure drainage.
4. Drainage behind retaining walls.
5. Garden and sports ground drainage.
