2.5/4m drainage net production line

The drainage net is made of high-density polyethylene. Through a special die head, ribbons are extruded. Three ribbons are arranged at a certain distance and angle to form a spatial structure with drainage channels. The drainage channels formed between the three ribbons are not prone to deformation under high loads, which can prevent geotextiles from embedding into the net core and ensure smooth drainage. The three-dimensional drainage net is usually single-sided or double-sided composite geotextile, forming a composite drainage geotextile net. Its drainage capacity is equivalent to that of 1 meter thick gravel. The product is mainly used in areas such as landfill drainage and road drainage.
