The Ekspan 302/51 and 302/2 through deck drain units provide spot sub surface drain points or wide area water collection when used with the 325 channel system. Corresponding 325 outlets will fit into either of the 302/51 or 302/2 funnel types. These are available in 50mm or 32mm. The 32mm system is ideal to drain a bridge deck between pre-stressed beams in retrofit applications.
