Geotextile mats are a new type of geosynthetic material made from randomly oriented fiber melt-blown mesh. They have high compressive strength and a large opening density, providing omnidirectional water collection and horizontal drainage functions. The structure consists of a three-dimensional geonet core, with needle-punched perforated non-woven geotextile on both sides. The three-dimensional geonet core can quickly drain groundwater and has a pore maintenance system that can block capillary water under high loads, while also serving to isolate and reinforce.
