We have drain connectors made from high quality EPDM for circular downpipes; which are placed into pre-cast holes along the horizontal deck on the roof or podium. Corner fittings are available for holes on the junction of horizontal and vertical parapet wall, usually running through the wall and into HDPE drainpipe.

Circular outlets are designed to be secured around the drainage hole and sandwiched between two layers of waterproofing membrane. We supply a circular drain connector with a smooth flange, a circular drain connector with perforated flange, and our special Siphon outlet drain connectors to prevent bad odours from escaping though the drain.

Circular roof outlets are installed across the deck area approximately 25-30m2 apart. They are designed to be mechanically fixed or stuck with adhesive. They are suitable for bituminous or EPDM membranes. Click here for more details		Circular roof manufactured with a perforated flange and a ribbed shank for more secure bonding.
