About this asset

Grey plastic circular puddle flange Revit family, designed as a 50mm sub-slab leak control component with an integral wide waterproofing rim. Modelled as a single-piece moulded drainage fitting, this component features a wide horizontal circular rim surrounding a recessed collar with an integrated central opening for 50mm pipe connections. Raised retention lugs sit along the inner recess to seat grate inserts or membrane clamp rings, while the outer flange provides a broad surface for bonding liquid waterproofing membranes. The lower body transitions into a cylindrical spigot connection beneath the flange plane. Surface details reflect utilitarian injection-moulded construction with uniform matte grey plastic texturing and standard concentric drainage contours.

The download is a 369 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Loading this RFA element into Autodesk Revit allows MEP engineers and architectural technicians to establish floor penetration levels and coordination points for wet area drainage. Insert the family aligned to structural slabs or floor finishes before connecting downstream pipework. Placed within MEP coordinating views, it ensures penetrations avoid structural rebar or post-tension cables and assists in producing clash-free plumbing shop drawings.

Suited to multi-residential bathrooms, commercial shower facilities, laundries, and balcony drain assemblies, this floor waste flange coordinates seamlessly with waterproofing detailing. It is essential when preparing construction documentation and MEP schematics for wet areas requiring continuous waterproofing membrane integration. Specifiers and hydraulic designers commonly pair this leak control flange with vinyl floor wastes, tile inserts, and standard cast-in-slab drainage layouts across residential and hospitality projects.
