Green Sanjiang waterproof material PVC drainage board is made of high density PVC material extrusion molding, which make full use of PVC material density, high strength, the material properties of amorphous structure made of cross drainage board. It is the use of cross support column and top post intermediate additional patented design, the use of large flat top and middle column are arranged in the form of support columns, to ensure complete soil cover does not sag after geotextiles, leaving enough space for smooth drainage. Purpose: Garden / Green Project: garage roof greening, roof garden, soccer fields, golf courses, and other green projects; Construction: building the basis of the upper or ground floor, basement and outside walls, roof and insulation layer impermeable and other details are as follows : 1, PVC drainage board is based on the principles of mechanics using the support columns plus intermediate head column structure, through a combination of high and low post, grass grid, geotextile not sag after casing to ensure adequate drainage space. Strong resistance root. 2, PVC drain due to the high density, with a strong root partition can be adjusted according to the requirements of every root thickness of the film to achieve the effect of every root, grass grid manufacturers of the total distribution, and tear. 3, compressive strength, PVC drain compressive strength, its compressive strength is equal to 1.5 times the thickness of the membrane PS, 2.5 times the HDPE material. H20 Drainage Board 0.7mmPVC material thickness compressive strength 300kpa above, and the same thickness compressive strength of PS and HDPE material only 150kpa about. Because of its unique design Strengthening rib structure generally flattened cars in any of the above is not straight support column. This is the other PS and HDPE materials can not be achieved. 4, both hot bonding can take, because the PVC material is non-crystalline structure, the use of special glue can effectively destroy the surface structure of the material so that the two-layered film can effectively fused together, so that the construction after the completion of a watertight compartment root function . Also available mechanical hot pick. 5, the second waterproof, drainage membrane unpaved access thanks to an adhesive or hot form, thereby forming a new waterproof layer, that have secondary drainage waterproof. Sanjiang green grass grid manufacturers to provide: also known as lawn grass grid protection pad can be used for green lawn parking, green lawn fire exits, fire climbing surface green lawns, roof gardens, lawns, parks, plastic grass grid, greening rate of 95 % to 100%. Grass grid from HDPE material, nontoxic, pressure, UV, grass powerful. Summer sunshine reflecting small, to prevent urban flooding, subsidence, etc. are obvious functions; reducing dust, it is excellent with natural plant ecology and environmental protection products. Product convenient pavement, simple construction, can be freely extended to the desired area, and free disassembly, suitable for large areas of pavement. Grass grid wholesale, grass grid, Shandong Green Sanjiang (view) provided by the Tai'an City Green Sanjiang waterproof material Limited.
