ABSTRACT:
A composite sheet material for use as a planar drain and a protection board. The sheet material has a multi-layer construction formed into a composite by needling. The multi-layer construction preferably has a layer of a soft nonwoven fabric material sandwiched between outer layers of a stiffened fabric material. The composite material may be configured into relatively narrow longitudinal strips for use as a wicking drain. Such longitudinal strips may often have a width of approximately three (3) inches or less in exemplary constructions.
