Waterguard Basement Waterproofing Drainage Channel System Accessories - Waterguard Corners.
These are actual pieces of Waterguard, pre-mitred and joined together.
Each corner is hand made from a 1ft length of Waterguard so they reduce the amount of Waterguard that you need to buy by 1ft for each corner, so don't forget to factor that in when deciding how many feet of channel that you need.
> They come in four types - See diagram below
> Order each type separately
> They save valuable time on site having to mitre your own Waterguard
