Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess of water. A lot of construction projects, such as roads, railroads, tunnels, landfills, solid waste treatment plants, bridges, water treatment plants, urban pipelines, reservoirs, embankment, airfields, sport fields, parking lots, dikes and so forth, need drainage facilities to keep the whole structure safety and stable.
Geotextiles are synthetic textile fabrics specially manufactured for civil and environmental engineering applications. Geotextiles are designed to retain fine soil particles while allowing water to pass through.
YINGFAN composite drainage network is a high strength HDPE geocomposite comprised of a bi-planar or tri-planar geonet core, heat bonded on both sides with nonwoven geotextile filters that prevent clogging and provide unobstructed linear flow channels. Compared to natural stone drainage layers, our products provide more strength and a permeability of ten times that of drainage Stones. In addition, the void maintaining triplanar core prevents the top and bottom geotextiles from touching, even under extreme loads.
