I am going place the Basedrain into a rebate at the wall/floor junction. What are the dimensions?
A. A newly formed rebate should be 100mm wide x 50mm deep and formed dead level. If you are not confident in forming the rebate dead level and to a uniform 50mm in depth, for to 80mm in depth. A cut recess in an existing slab should be 100mm wide x 50mm deep. Where the recess is deeper than 50mm, use 20mm clean graded stone to fill the recess to within 50mm of the top of the slab or raft. The stone helps to level the Basedrain where the recess is not level.
