Abstract (en)

A concrete drainage component has a lightweight block (10) with a channel (12) accessible through a continuous slot (14) whereby the block (10) can be end pressed. A plurality of tops (30) seat across the top of the block (10) and each top (30) has a recess (34) in each side. When adjacent tops (30) abut a transverse slot is formed through which drainage can take place into the channel (12). The tops (30) can also be pressed and therefore the component can be simply and economically produced.
