TerraDrain® Sheet 100/2 prefabricated drains are constructed using a perforated, high strength, high flow capacity, formed polystyrene drainage core with a nonwoven filter fabric bonded to both sides. The filter fabric prevents soil intrusion into the flow channels while allowing water to freely enter the drain core from both sides.
TerraDrain® Sheet 100/2 products are designed for subsurface, double-sided drainage applications requiring a high compressive strength and flow capacity. TerraDrain® Sheet 100/2 is available with filter fabrics meeting AASHTO M 288-06 specifications.
