TerraDrain® Sheet 203 prefabricated drains are constructed using a high strength, high flow capacity, formed polystyrene core with a woven filter fabric bonded to one side. The filter fabric is bonded to each dimple to prevent soil intrusion into the core flow channels while allowing water to freely enter the drain core. The core provides an uninterrupted path for water to flow to designated drainage exits.
TerraDrain® Sheet 203 products are designed for subsurface, single-sided drainage applications requiring high compressive strength and flow capacity. TerraDrain® Sheet 203 is constructed using AASHTO M 288-06 Class 2 filter fabric.
