Connect two pieces of basement drainage channels at corners with this easy to use connector. 



Corner Drainage Channel

PermaSEAL Drainage Channel Corners seamlessly connect two PermaSEAL drainage channels at any corner. These 90° smooth plastic drain corners allow water to flow easily around a cavity drain system, protecting structures from hydrostatic water pressure.

These corner drainage channels can be used around the perimeter of a structure or in any central drainage installed across the floor. With a simple push connection, they connect effortlessly to PermaSEAL drainage channels both with and without upstands. There is no need for tape.  

They can be installed below flooring membranes at the corners of floor-wall junctions or across the centre of the floor/slab when a 90° connection is required.

We have focused on an innovative design that means the internal surface of the connector and channels remains flush. This avoids the unwanted build up of salts and silt and other debris that could cause issues. 

Installing a corner drainage channel

The drainage channel corners are easy to install as part of PermaSEAL’s complete drainage channel system. The corner unit and drainage channels simply slot together. There is no need to tape the joints. 

The corner drainage channels are part of our full range of PermaSEAL connectors and drainage channels:
