Shanghai plastic drainage board manufacturers 156-6693-5556 Shaojing Li plastic drain more information, please contact Geo Da Xing, http: Advantages //www.slfhpsb.com plastic drainage board: HDPE plastic drainage board used environmental data, thus also known as HDPE drainage board, HDPE itself that is an excellent waterproof material, HDPE drainage board to become an excellent assistant waterproof material. High-density polyethylene (HDPE) is also an olefin-based materials, its molecular structure nonpolar, thermoplastic, high hardness, high strength, deformation extension function, high tear strength, plastic drain biggest feature is the resistance to environmental corrosion good, usually acid, alkali, salt corrosion damage can not constitute HDPE. Drainage board thickness is very thin, sharp saves construction space, there is a level of hollow stud layout, clear hierarchy can quickly discharge rainwater useful and greatly reduce or even eliminate the hydrostatic pressure waterproof layer, drainage board can usefully maintain structures and waterproof layer against various types of soil pH and thorn plants, but also in the basement wall backfill, HDPE drainage board can maintain the buildings and waterproof layer from damage. Soft reinforced plastic drain advantage: 1. treatment is good, smooth drainage, drainage effect is guaranteed. 2. The material has good strength and ductility, the ability to fit ground deformation without affecting the drainage performance. 3. Drain the section size is small, the process of applying to fight the foundation drains little disturbance. 4. flapper construction in the ultra-soft ground. 1, the difference between the drainage board functional after backfill settlement between bumps easily blocked drainage channels, drainage ineffective, if displacement or use big words in the roof garden, you should use water on board. 2, build drainage board can prevent thorn, and indeed can not drain. 3, drainage board construction faster, but more difficult construction, build drainage board construction is simple, but the slow construction. 4, the material cost is higher than the drainage board build drainage board. Because when laying drainage board, the support network needed to prevent backfill affect drainage geotextile sink effect. Laying drainage board rules: 1. Clean the site of rubbish laying cement leveling, so there is no obvious bump at the scene, an outdoor garage roof and roof garden need to find the slope of 2-5 ‰. 2. Green roofs and outdoor garage roof greening can be equipped with a porous pipe use, so can drain the water discharged into a local focus under or near the city sewer pipes. 3. Ground water seepage in the basement, on the basis of the above overhead floor, which is done in front of the floor drain is to do one round projections downward, left around the blind ditch, groundwater up the mountain, through natural seepage inflow drainage board space around the blind ditch, and then through the blind ditch into the sump. The interior basement seepage water, the body can be laid on the building wall drainage board, round projections for the main walls, drainage board outside and then a layer of single-wall masonry or cement powder steel mesh to protect the drainage board, so space outside wall seepage board straight down the inflow blind ditch directly caused sump. 5. In any lot laying drainage board, must be careful not to let dirt, cement, sand and other trash into the front space of the drainage board to ensure the smooth flow of the drainage board space. 6. When do the protective measures laying drainage board as possible, dimensions or outdoor garage laying drainage board should backfill work in a timely manner as soon as possible, to prevent large wind in laying drainage board affect quality; and interior basement waterproofing protection to do as soon as possible layer to prevent drainage board is damaged or things. Drain a range of applications, greening projects: garage roof greening, roof garden, vertical greening, green sloping roofs, football, golf. 2, municipal engineering: airports, road embankment, subway tunnels, landfill. 3. Construction: building the basis of the upper or lower, basement and outside walls, roof and insulation and other impervious. Traffic Engineering: roads, railway embankment, dams and slope protection layers. Product quality and after-sales service and engineering experts praise the majority of users. Customers willing to colleagues and the community work together, sincere cooperation for a better tomorrow!
