| For use with bituminous or multi-layer waterproofing membranes. The shallow balcony outlet has the same features as the standard balcony outlet, but with a shallow sump and extended spigot. This allows the sump to be accommodated within the thickness of the screed/structural concrete, without having to cut reinforcing steelwork. The pipe spigot is extended to project below the slab for ease of connection to pipework. Outlets for use with 63 or 76mm aluminium pipework are available to order.
