Supply Hubei drainage board @ build drainage board manufacturers = bearing capacity Contact [Li] (182 6481 7103) QQ: {46-37-96-887} to look forward to sincere cooperation with you build drainage board build stereotypes formed by heat and pressure of a drainage board using high-density polyethylene (HDPE) or polypropylene (PP) both to create a support stiffness drainage channel with a certain three-dimensional space, but also a light sheet of water. The sheet with water, drainage two plates has the characteristics of high spatial stiffness, resistance to stress was significantly better than similar products (field test test), able to withstand more than 400Kpa high compressive load, at the same time in the planted roof can withstand extreme load conditions backfill mechanical rolling process. To create a layer of drainage, infiltration of water within the soil discharge, deposit build part of the infiltration of water and other functions ★ existing garage roof, roof garden, to planting green roof drainage board chemical name called build drainage board ~ material is divided into high-density polyethylene material plastic drainage board polypropylene drainage board is HDPE drainage board, HIPS plastic drain board to build drainage board has the following advantages and disadvantages compared to the previous generation of drainage products: 1, Northern drought, water drainage board storage, conducive to the growth of vegetation ; 2, build drainage board bump thicker sidewall, the compressive strength, can reach more than 40T, far greater than the plastic tabs (high-density polyethylene drainage board, high-impact polystyrene drainage board), plastic drainage mat and other similar products (solid rolling experiment), to meet the backfill construction requirements and uptime requirements; 3, build drainage board support surface is relatively large, neither the overlying non-woven subsidence, blocking drainage channel, it will not tear due to lack of non-woven pull the soil into the blockage of drainage channel, build drainage board complete reservations drainage space, completely avoid the plastic tabs non-woven subsidence lead to poor drainage. will not cause vegetation to wither and die because of poor drainage.
