Eljen’s PDS is a nonaggregate drainage system made from recycled materials that can be used for surface and subsurface drainage. It features a plastic core material, which provides hydraulic conductivity, enveloped in geotextile fabric, which protects the drain from clogging over time. PDS panels come in various sizes to meet an individual site’s needs and can be assembled and positioned into trenches from the surface, reducing site impact and increasing safety on the job site. 800-444-1359; www.eljen.com.
