Have a butchers at 'Part J' & 'TB 009' mentions using dense brick/concrete, not Celcon (aerated) block to build up the catchment area.
Other than that the catchment area would be porous and could potentially allow the passing of POC's through it, so would be AR.

by definition a catchement space must be complete and contain the POC's, and only have one entrance and one exit, so if the blocks are porous oor aereated the POC's can travel through to an area they are not allowed to go to
