Green Sanjiang brand build drainage board construction laying Notes: 1, 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, drainage board covered with geotextile, geotextile overlap each 10 ~ 20cm, to prevent mud and water through the geotextile cloth, clogging build drainage system, resulting in poor drainage, reduce storage capacity; high compressive plastic drainage board only drainage function, widely used in retaining walls, basements, tunnels, slope and highway embankment. Alias ??plastic drain drainage board, there are a variety of shapes wavy, harmonica type. Drainage board is a combination of the advantages of foreign brands Linyi drainage board build drainage board wholesale agents, according to China's geology developed more advanced Soft and super soft foundation reinforcement of new materials, with a large hole cross section, smooth drainage, quality light, tensile compressive strength characteristics. Intermediate drainage board is an extruded plastic core, skeleton and channel drainage belt, which was parallel cross section, two non-woven geotextile filter layer package for Linyi build drainage board wholesale spot, and will play a supportive role with core discharge filter layer of water seeping up silt, silt soil quality, and other saturated hydraulic fill filling viscous and miscellaneous drainage consolidation method using soft foundation treatment of good vertical channels, greatly reducing the soft soil consolidation time. We welcome all new and old customers to negotiate business and cooperation, common prosperity! Provides you build drainage board, plastic drain, grass grid, drainage board manufacturers, drainage board prices, drainage board wholesale, drain construction! Green rivers drain license plate is made of polystyrene (HIPS) or polyethylene (HDPE) plastic floor made after punching cone penetration units (or hollow cylindrical porous) from cone penetration units of bonding the top surface layer of filter geotextile to prevent soil particles through, in order to avoid blocking drainage channels, drainage channels so smooth. Good drainage system for normal use and life cycle of civil construction and structures play an important role. YS type Drainage Board porous tubes with an efficient drainage system, dredging long and short cylindrical drainage plate and geotextiles to form a drainage system, build drainage board wholesale Linyi, thus forming a water seepage, water and drainage features . Drainage Board Applications: 155-5283-7377 PSb20 performance and application PSb20 drainage board is made of high impact polystyrene (HIPS). Coupled with a layer of non-woven fabric surface to form a composite drainage board. YS-PSb20 be single boss drainage board, only drainage function, compared with PSb20, PSb20 greater displacement. Suitable for relatively deep soil water holding capacity and do not need a large square green, garage roof greening projects.
