PermaSEAL Drainage Channel is used to relieve hydrostatic water pressure and is installed below flooring membranes at the floor wall junction.


T Junction Drainage Connector 

PermaSEAL T-Junction drainage connectors are used with PermaSEAL Drainage Channels to relieve hydrostatic water pressure. They allow you to easily connect perimeter drainage channels to a cross-floor drainage run at a 90° angle.  

These T-junctions make it simple to change direction in any drainage channel run, helping you design a drainage solution for your basement or structure.  These T-connectors are installed below flooring membranes at the floor-wall junction. They help you channel any water entering your cavity drainage system to a sump chamber or suitable outlet wherever it is located.

PermaSEAL drainage T-connectors simply slot together with the perimeter or floor drain channels. They form a smooth and seamless connection without the need for tape. We have focused on an innovative design that means the internal surface of the T-Piece connector and three connecting drainage channels remains flush. This avoids the unwanted build up of salts and silt and other debris that could cause issues. 

Installing Drainage T-Piece

The T junction drainage pieces are easy to install as part of PermasSEAL’s complete drainage channel system. The drainage channels slot into the T-piece without the need to tape the joints.

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