UltraSlot F900KN is a surface drainage system designed for external pavement areas subject to constant traffic by large aircraft and heavy-duty vehicles. It is available in six channel sizes, 6 to 24 in. wide, which can be interconnected within a single channel run. The system reduces underground pipe work, catch-basins, and manhole chambers. Offering jobsite efficiency, contractors can install it up to four times quicker than alternative drainage systems. Elkington Gatic. 888-869-1116. www.slotdrain.com/usa
