Established in 1970, Eljen Corporation created the world’s first prefabricated drainage system for foundation drainage and erosion control applications. In the mid-1980s, we introduced our Geotextile Sand Filter (GSF) products for the passive advanced treatment of onsite wastewater in both residential and commercial applications. The GSF system is your tight lot, high water table and poor soil solution used throughout the world.
