Production on the continuity of the process. Ensure the accuracy of the distance between the unified drainage board boss, thus ensuring the accurate edge overlap between the bosses. Advanced production technology determines the flat edge of the drainage board width of neat. Single-sided boss row sparse board, a variety of sizes socket or edge gluing, dry with a construction company boss socket, and self-adhesive, temperature row sparse board construction can guarantee the quality of the side access. Too fast laying promote and improve the construction schedule, shortened one. [Five] have strong flexibility, compact configuration and a relatively high compressive strength row sparse board production process on the boss structure design is reasonable, the deployment of chemical ingredients, so sparse row of panels with high density polyethylene softness, but also has high impact polystyrene hardness, so row sparse board strength and security, it is easy to moderately soft handling, transportation, laying and construction. Drainage Board - Manufacturing 183-6660-9127 Shandong Traffic Engineering: roads, railway embankment roads, dams and drainage slope back municipal engineering: road embankment, subway tunnels, landfill groundwater and surface water discharge guide construction projects: building foundation upper or lower, basement and outside walls, green roofs and drainage impermeable insulation and other green projects: construction cone garage roof greening, roof garden, soccer fields, golf courses, bathing and other construction works drainage board penetration units (or hollow cylinder shaped porous) plastic floor, from high-impact polystyrene (HIPS) is made. Cone penetration units (or hollow cylindrical porous) bonding the top surface of a non-woven filter layer to prevent soil particles through, thus avoiding the obstruction, so that smooth drainage. Advantages drainage board use of traditional brick tile drainage as a guide filter layer, the use of more pebbles or gravel as a filtration layer, the water discharged to the designated place. Now replace the pebbles treatment layer with a drain to drain is saving time, effort and energy saving investment, and reduce the load of the building. Drain well-functioning drainage system for normal use and life cycle of construction and civil engineering structures play an important role. Drainage Board Drainage Board porous tubes with an effective drainage system sparse, long and short cylindrical drainage plate and non-woven fabrics to form a drainage system, to form a water seepage, water and drainage features
