Filtration Critical

Filtration critical products offer a wide selection of hydraulic-based characteristics to function well in enabling water flow with limited to no clogging or soil piping. With monofilament yarn inclusions, these products work well in difficult applications such as shorelines, planter or green roof systems, and both infiltration and exfiltration systems. Each of these woven geotextiles is composed of high-quality polypropylene resin and carbon black.
