EPDM Drain Connectors and Outlets

Tough, durable and flexible drain connector, used for downpipes and circular outlets on a roof or terrace within the main body of a concrete deck. It is suitable with SBS and APP bituminous membranes, including built-up felt, mastic asphalt, hot melt and other liquid applied membranes and consists of a spigot which is inserted into a hole to connect to the outlet drainage pipe and a flange which is sandwiched between two layers of waterproofing membrane. The flange is perforated with a series of holes around the profile to allow the membrane underneath to pass through the holes and give a secure bond when the second layer of membrane is installed above it.

The spigot is manufactured in a slight cone shape to give easy installation and to prevent it from rising out of the hole. There are also multiple rings on its exterior, which help to ensure that no water can travel back up. The drain connectors are designed to sit inside an HDPE outlet pipe with a snug fit and a range of size options are available in relation to the relevant outlet pipe size.
