Hydrodrain 300 is a composite drainage system consisting of a three-dimensional , crush-proof drainage core and a non-woven, needle punched filter fabric. The filter fabric is bonded to the ridges of the face of the core. (Horizontal and vertical applications)

Hydrodrain 302 is a composite drainage system consisting of a three-dimensional, crush-proof drainage core and a non-woven, needle punched filter fabric. The filter fabric is bonded to the ridges of the core on both sides. (Horizontal and vertical applications)

Hydrodrain 1000 is a composite drainage system consisting of a three-dimensional, crush-proof drainage core and a non-woven, needle punched filter fabric. The filter fabric is bonded to the ridges of the face of the core. A fabric and polyethylene laminate protection sheet is bonded to the back side of the core. (Horizontal and vertical applications)

Hydrodrain AL is a composite air layer/drainage system consisting of a three-dimensional, crush-proof drainage core and a non-woven, needle punched filter fabric. The filter fabric is bonded to the ridges of the face of the core. (Horizontal applications only)

Hydrodrain 420 is a composite drainage system consisting of a three-dimensional "dimple" type polyethylene core and a non-woven, needle punched filter fabric. The filter fabric is bonded to the top surface of the core, preventing intrusion of the fabric into the flow channels during backfilling. A thin protective sheet is bonded to the backside of the core. (Vertical applications only)

Hydrodrain 700 is a composite drainage system of a three-dimensional "dimple" type polyethylene core and a woven filter fabric. The filter fabric is bonded to the top surface of the core, preventing intrusion of the fabric into the flow channels during backfilling. (Horizontal and vertical applications)
