Preformed DPM Corners

[Wenborn1989]

Hi,

Im looking to lay the DPM in our extension (walls already built). I’ve seen in a couple of old chats mentioning preformed corners as a time saver for external corners.

Can someone share a link to a product? I’ve seen some that could be used for roof waterproofing but I’m not sure they would be right for my application.

Thanks, W

How much time is saved over a couple of folds?

And how much risk is introduced with a couple of cuts?

Its not a big deal if there's a hole or 2 in your DPM. A roof needs to be watertight, so does a tanked basement or a wet room.
You can get special DPM tape or just use gaffa tape and offcuts where you have to make cuts.
