TerraDrain® Sheet 104-T prefabricated drains are constructed using a high strength, high flow capacity, formed polystyrene drainage core with a nonwoven, spun-bonded or woven filter fabric. The filter fabric is bonded to each dimple to prevent soil intrusion into the flow channels while allowing water to freely enter the drain core from one side.
TerraDrain® Sheet 104-T products are designed for subsurface, single-sided drainage applications requiring a high compressive strength and flow capacity. TerraDrain® Sheet 104-T is available with filter fabrics meeting AASHTO M 288-06 specifications.
