TerraDrain® Sheet 54

TerraDrain® Sheet 54 prefabricated drains are constructed using a formed polystyrene core with a nonwoven 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 54 is an economical solution for sub-surface, single-sided drainage applications requiring moderate strength and flow capacity. TerraDrain® Sheet 50 is available with filter fabrics meeting AASHTO M 288-06 specifications.
