SITEDRAIN HQ 240
PREFABRICATED COMBINATION DRAINS
SITEDRAIN HQ 240 prefabricated combination drains combine our most popular low-profile sheet core with a high-profile core
into one product design. Constructed using a graduated, high flow capacity formed polystyrene drainage core, SITEDRAIN HQ
240 has a nonwoven filter fabric bonded to one side. The fabric prevents soil particles from entering the flow channels while
allowing water to freely enter the drainage core and flow to designated exits. SITEDRAIN HQ 240 has a core flange for connection to SITEDRAIN Sheet Drain products to provide a continuous and uninterrupted flow path for collected water. The result is a
highly cost-effective design alternative to costly pipe and stone systems.
