Waterguard Basement Drainage Channel inspection ports
For DIY and professional Basement Waterproofing
You should install these in the Waterguard channel along side every wall, they are not always essential but if you think there is any risk of silting of limescale build up(if a lot of new concrete has been used for instance) you wiil need them.
These are our own new improved diesign with many advantages over the old Basement Systems' design, for example, they are telescopic so that their height can be adjusted precisely to be level with the floor, the lid is hinged, not loose and makes a good air-tight seal when closed.
