Abstract
A drainage installation (20), for a warehouse and/or factory floor that has a surface level (26), has a drainage channel (24) recessed into the floor and a plurality of sections of flat grating (22) seated inside the drainage channel (24). The drainage channel (24) has an axially-elongated, square-U shaped channel portion which is flanked by horizontal shoulders (30), which then transition into vertically-depending skirt portions (32). The horizontal shoulders (30) as well as the sections of flat grating (22) are arranged to be more less planar with the surface level (26). Wherein, the skirt portions (32) are formed with a series of apertures (36) which either allow the injection of wet cement underneath the shoulder portions (30) of the drainage channel (24), or alternately the venting of the wet cement when the cavity under the shoulder portions (30) are over-filled.
