The U-shaped section of Yete@ drainage ditch can accelerate the water flow and enhance the self-cleaning ability. Through scientific hydraulic calculations, the finished linear gutter system can meet the requirements of aesthetics, efficient drainage, noise reduction and bearing capacity compared to the traditional practice of cast-in-place construction. Resin concrete has the characteristics of corrosion resistance, anti-freeze and anti- seepage, smooth surface, high drainage efficiency, high strength and long service life.
