Green Sanjiang build drainage board 500mm * 500mm, height 2 cm, 2.5 cm, 3 cm in three sizes. Build drainage board is used for roof planting water drainage. Build drainage board laying down the boss, waterproof material surface with a solid and stable base layer of paving, fully consistent with snap fasteners on both sides. Convenient and simple construction. Build drainage board's role: 1, northern drought, build drainage board can water drainage board, conducive to plant growth; 2, due to the bumps fryer drainage board is relatively thick, so the compressive strength is large, much larger than the plastic tabs, plastic drainage mat and other similar products; 3, build drainage board can retain the integrity of the drainage space, the support surface is relatively large, to avoid the plastic tabs nonwoven subsidence due to poor drainage cause to happen, because neither subsidence of overlying non-woven blocking drainage channels, it will not lead to tearing due to lack of soil into the nonwoven fabric tension and blocked drainage channels will not be due to poor drainage cause vegetation wither and die. 4, auxiliary water green rivers drainage protection board on the starting material - high-density polyethylene geomembrane which itself is a good waterproof material, welded lap mode can Tianhai drainage protection board to build into a complete whole, under seepage in flow drainage protection board can be isolated under water seepage and waterproof layer, waterproof layer to avoid immersion in water. It is laid on the roof waterproofing underground construction can play a good supporting role of water. 5, does not find the underground garage roof Osaka layer settings to find the slope layer is intended to increase the water potential to increase the rate of drainage drainage board two centimeters and a half, but for larger planting platform, slope gradient can not find much on the increase Large drainage rate that much, and to find the slope cost is very high, there is no need to find the slope layer set. As long as the water potential difference can exist water flow, even if the roof did not find the slope layer, water will accumulate water potential difference between the plastic drain outlets, the same can flow. Of course, if you do not find the slope of a small amount of water finally retained on the roof, but that part of the water does not pose a hazard to plant growth, but it can be absorbed by the soil. Sanjiang green roof planting basement drainage protection board Universal plate 2 cm Drainage Board (storage), use it to build a water permeability human intervention conditioning systems, is the water permeability, anti-plant roots puncture, flexible protective waterproofing system, combined with a variety of functions in integrated system, in order to achieve waterproof, protection, backfill three working steps simultaneously, it is to create a planted roof basement. The most economical, scientific and rational, fast and convenient approach. 3 cm drainage board prices, Yao Chen (certified), Tibet drain by Tai'an City Green Sanjiang waterproof material Limited.
