Description
TerraDrain® sheet drains are constructed using a polymeric core with a nonwoven filter fabric bonded to one side. The filter fabric is designed to prevent soil intrusion while allowing water to freely enter the drain core, which provides an uninterrupted path for water to flow to designated drainage exits.
