Description:
Product specifications：Plastic blind drain is plastic synthetic resin melted through the nozzle extruded filaments are stacked together, the three-dimensional porous material and its contact melting into the subject, in the outer package of geotextile as membrane,porous hollow rectangle,rounded rectangle, porous,hollow circular four the structure form, with a variety of dimensions.
Performance characteristics：
High compressive strength,good pressure resistance；
Surface high hole rate,drainage is good；
Permanent service life；
Selective membrane。
Convenient construction：Good flexibility to adapt to the deformation of soil。
