ABSTRACT:
A surface drainage system comprising base members (27) and cover members (32). The base members have a channel formed between opposite walls thereof, and are designed to be laid end-to-end with the channels in longitudinal alignment. The cover members are of inverted channel section and have opposite side walls with a channel defined therebetween. The cover members are laid above the base members and combine therewith to form an enclosed drainage channel. Each cover member has at least one opening (37) extending through a side wall thereof and communicating with the channel. The lowermost part of the opening intersects the outer surface of the respective wall at a location (36) that is no closer to the bottom than to the top of the cover member. A carriageway (35) can be laid with its surface no lower than the point (36), so that drainage is effected through the opening (37) while the base members (27) lie at a significant depth below the carriageway surface.
