SITEDRAIN Sheet 90 Series 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. SITEDRAIN Sheet 90 Series is an economical solution for sub-surface, single-sided drainage applications requiring moderate strength and flow capacity. SITEDRAIN Sheet 90 is available with filter fabrics meeting AASHTO M 288-06 specifications.

SITEDRAIN Sheet 180 Series 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. SITEDRAIN Sheet 180 products are designed for subsurface, single-sided drainage applications requiring a high compressive strength and flow capacity. SITEDRAIN Sheet 180 is available with filter fabrics meeting AASHTO M 288-06 specifications.

SITEDRAIN Sheet 450 Series prefabricated drains are constructed using a high strength, high flow capacity, formed polystyrene drainage core with a nonwoven, spun-bonded or woven filter fabric bonded to one side. The filter fabric is securely bonded to each dimple and prevents soil intrusion into the flow channel while allowing water to freely enter the drain core from one side. SITEDRAIN Sheet 450 products offer a compressive strength and flow capacity that is significantly higher than geonet products, making it the ideal choice for high stress applications. SITEDRAIN 450 Series is available with filter fabrics meeting AASHTO M 288-06 specifications.

SITEDRAIN DS-180 Series prefabricated drains are constructed using a perforated, high strength, high flow capacity, formed polystyrene drainage core with a nonwoven, spun-bonded or woven 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. SITEDRAIN DS-180 products are designed for subsurface, double-sided drainage applications requiring a high compressive strength and flow capacity. SITEDRAIN Sheet 180 is available with filter fabrics meeting AASHTO M 288-06 specifications.

DELTA®-DRAIN is an effective method to control the flow of damaging soil moisture through cracks and gaps in below grade structures, while relieving hydrostatic pressure. It is comprised of a multi-layer geocomposite combining a high compressive strength core with a geotextile, bonded to the core for lasting durability. DELTA®-DRAIN creates an essential path for the vertical and horizontal drainage of soil moisture and filtering of soil particles.
