The Ultimate Geocomposite High-density polyethylene (HDPE) Rolle d Matrix Dimpled Drainage and Soil filter System.
TechnoFix® DrainMate is a high-performance, high-strength Geocomposite drainage and protection sheet consisting of a three-dimensional layer of polypropylene geotextile fabric with continuous-filament yarn and a high-density polyethylene (HDPE) dimpled membrane. The filter fabric is bonded by thermofusion to the individual dimples of the molded polypropylene core to minimize fabric intrusion into the flow channels caused by overburden pressure. Due to the special orthogonal drainage channels, TechnoFix® DrainMate ensures excellent drainage and creates an air chamber that allows for higher volumes of water to be drained compared to traditional dimpled membranes. The action of the geotextile fabric ensures a constant filtering of soil particles and prevents the obstruction of drainage channels.
