Wenzhou pvc common specifications 16mmpvc drainage board Drainage Board, 18mmpvc drainage board, 20mmpvc drainage board and other specifications, special specifications can be customized. PVC drainage board widely applied to green roofs, underground garage roof greening, golf courses, lawns stadium drainage, and a lot of water in the pillar. Each block can be between one another snap, paved drainage board covered with a layer of geotextile fabric to form a composite drainage board. Construction PVC drain Note 1 for garden flower beds, planters and flower beds, the direct hydrophobic plate and filter geotextile instead of conventional materials (such as ceramic, pebbles or shells composed of a filter layer). 2. For new and old roof or underground works in the roof and other hard green screen when laying drainage board before the first clean up the site of debris, set up in accordance with the requirements of design drawings waterproof layer, from the slope and then cement mortar, the surface free obvious bump at the hydrophobic plate orderly discharge, lay within the range without additional provision of drainage ditch blind. 3. For a construction sandwich board, build drainage board laying on the roof on a concrete slab, and then assemble the outer layer of hydrophobic plate single wall, or with concrete to protect that flow into underground water seepage through the blind ditch drainage board to set the overhead space puddle. 4. PVC drain stitching around each other, laying the gap as the lower drainage channel, on which the filter geotextile layer when moisture also need to lay a good lap. 5. PVC drain after laying is completed, it may be the next process, laying a good filter geotextile layer and the substrate as quickly as possible, prevent soil, cement, sand-clogged pores or consider water into the hydrophobic plate, sink, drainage channels. To ensure drainage board to fully play its role while covered in geotextile filter above the operation panel, to facilitate green construction. PVC drain construction laying method. Waterproof layer and protective layer construction is completed, start paving drainage board. Drainage slope requires grassroots meet 2 ‰ ~ 5 ‰; 2. The drain cup-side up pavement, interlocking perforation; 3. Drain cover on top of geotextile, geotextile overlap each 10 ~ 20cm, to prevent mud and water through the geotextile, clogging drainage system, resulting in poor drainage, reduce the amount of water treatment; 4. Geotextile covered it in 10 ~ 20mm in sand to form osmotic filter layer can prevent the planting soil erosion; 5. Appropriate planting soil cover thickness. 6. To do the drainage board product protection. After the drainage board pavement, drainage board should not allow direct pushing trolleys, laying wood, bridleways transport material. To do with the shop with the filling. PVC drain in recent years developed a new drainage materials, it is a blend of modified polymer (PVC) high density PVC as the basic raw material, the use of a membrane shell made of special technology continuously overall drainage membrane, it has a certain rigidity and support stereoscopic drain space permitting liquids, gas flow in the inner and rapid discharge / due to raw material itself is unique physical and chemical properties, PVC waterproofing and drainage board has in common besides the same drainage board drainage function, with a unique anti-plant thorn feature, it can effectively cut off the plant roots over the layout to permanently protect the building's structural waterproofing layer from damage; additional PVC unique weldability make drainage protection board After welding has excellent overall performance of water seepage, giving the building adds a layer of waterproof protection, but also further ensure the integrity and systemic anti-plant thorn functions, while achieving water, drainage, and other root resistance effect one role. PVC drainage board for the garage roof or green roof greening, high compressive strength, load light. Bump up laying, forming gaps between layers and geotextile composite, with a lead water drainage, auxiliary waterproof, resistant to root puncture protection, ventilation, noise, thermal insulation, moisture and other functions: (1) Lead water drainage. Drainage board has an uneven surface of the hollow structure, and geotextile structure, can quickly and effectively to rain or other water export, reduce or even eliminate the hydrostatic pressure waterproof layer, this automatic drainage can improve the waterproof performance of the projects, to extend the project life . (2) storage performance. Sided drainage board features a unique recess can store some of the water, when the soil is thin plants to ensure water absorption. (3) water resistance. Drain board material itself is a good waterproof material, using a reliable manner lap, it can be a good waterproof layer. (4) Root puncture resistant properties. Protective plastic drain board material is resistant to plant roots puncture resistance for planted roof, can drain, but also improve the roofing plant roots puncture resistance performance. (5) The protective properties. Protective plastic drainage board can resist acid and alkali soil erosion, protect buildings and waterproof layer. Backfill in underground engineering, can protect against damage to buildings and waterproof layer. (6) In addition, the drainage board also has insulation, light weight, ease of construction.
