Grey Cast Iron Square Promenade Roof Drain – RD-100-CP

Engineered for flat roof systems, this cast iron square promenade roof drain Revit family provides accurate MEP detailing for stormwater drainage. Constructed from coated heavy-duty cast iron, this assembly combines a square slotted strainer grate mounted in a recessed square rim frame above a circular clamping ring flange and sump body. The strainer features concentric rectangular drainage perforations with secured side fasteners to resist traffic loads while capturing stormwater runoff. Beneath the flush surface grille, the wide flashing collar accommodates waterproofing membranes, transitioning down into a cylindrical drain basin with a vertical outlet spigot ready for connection to primary vertical rainwater pipework stacks.

The download is a 328 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.

Load this family directly into Revit plumbing or architectural project environments. The component aligns with structural slabs or finished terrace deck levels, permitting seamless integration with waterproofing build-ups. MEP designers can assign appropriate connector systems to the outlet hub for standard pipe routing, slope management, and automated sizing calculations within building service coordination drawings and BIM clash detection tests.

Essential for flat roof drainage design, this drainage fixture suits commercial plazas, accessible roof gardens, balconies, parking structures, and industrial facilities. It coordinates alongside membrane roofing systems, deck pavers, and downspout drainage layouts across schematic MEP design through to tender submittals. Engineers seeking promenade drains, deck drains, or flat roof stormwater outlets will find this asset correctly detailed for technical construction documents.
