Green Sanjiang waterproof material PVC drainage board is made of high-density extruded PVC material, which make full use of PVC material density, high strength, material properties such as non-crystalline structure made of cross drainage board. It is the use of a cross in the middle additional support columns and roof pillar design patents, the use of large flat top and middle column are arranged in the form of support columns, to ensure complete soil cover after the geotextile is not sinking, leaving enough space for smooth drainage. Purpose: Garden / Green Engineering: garage roof greening, roof garden, soccer fields, golf courses, and other green projects; Construction: building the basis of the upper or bottom, basement and outside walls, roof insulation and other impervious and described in detail below : 1, PVC drainage board is based on the principles of mechanics using the support columns plus top middle column structure, through a combination of high and low post, geotextile not sag after casing, to ensure adequate drainage space. Radicular strong resistance. 2, PVC drain due to high density, with a strong root compartment can be adjusted according to the requirements of every root film thickness to achieve the effect of every root, tear strength. 3, compressive strength, PVC drainage board 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 at 300kpa over grass grid, and the same thickness of the PS and HDPE material compressive strength only 150kpa around. Because of its unique design structure for strengthening ribs cars in general are not squashed any straight above a support column. This is the other PS and HDPE materials can not be achieved. 4, both hot bonding can take, due to the crystal structure of a non-PVC material manufacturers grass grid, using special glue can effectively destroy the surface structure of the material so that the two-layered film can effectively fused together Tai'an grass grid, so that the construction is completed Waterproof played every root function. Also available mechanical hot pick. 5, the second water features, drainage membrane laying is completed thanks to the form of bonding or hot pick, to form a new waterproof layer that is waterproof and drainage functions with quadratic functions. Sanjiang grass green green grass Gert point presentation complete grid provides over 95% of the grass area, totally green effect, sound-absorbing, vacuuming, significantly improved the quality and taste of the environment. (Reference: Concrete grass brick, only 30% gap) to save and invest the parking and green grass grid functions into one, high cost of land in the city, developers can save valuable investment. Unique and stable level flat full grass grid plug-in lap the entire paved surface together into a flat overall, to avoid local depression, construction is extremely convenient. (Reference: Concrete grass brick each independently be pouring a concrete pad foundation, remain flat side) of high-strength, long life grass grid using patented technology, special materials, compressive strength up to 200 tons / square meters, more than specifications fire climb 32 tons Face / square meter. Performance stability, UV, acid corrosion, abrasion pressure, weather -40 ℃ -90 ℃. (Reference: grass brick concrete cracks easily damaged when the temperature changes and frost) drainage excellent load-bearing layer of gravel into the water provides a good function to facilitate the discharge of excess rainfall. Load-bearing layer of gravel turf protection provided some water features, favorable turf growth, roots can grow into the gravel layer. (Reference: Concrete grass brick only a small space, and in the summer sun at temperatures up to 50 degrees) green grass grid security and stability, recyclable and recycled, absolutely clean grass grid construction, comprehensive care lawn. Light saving grass grid 5 kilograms per square meter, extremely lightweight, quick installation, saving labor, shorten the construction period.
