I need to tank my cellar on a tight budget. I'm thinking of lining the
walls with damp proof membrane, held on with battons screwed with
stainless screws. The membrane will be left slightly slack between the
vertical battons to allow drainage of water.

I'm thinking of using guttering sunk into pea gravel at the wall/floor
junction, all draining into a sump in the corner. The floor, too will
be covered with membrane, not sure how to allow drainage or bond it to
the wall membrane yet though. The whole lot will then be dry lined
over the battons.

Is this going to go terribly wrong? As long as I can bond the membrane
together to form a watertight seal i can't see any problems.

The commercial studded membrane is way over my budget.

I can't comment directly on your suggestion - I don't have any
experience of tanking. But are you planning on using the cellar as
habitable space, or just wanting it to be a dry storage area? I use
mine for storage, and I've found that an £80 dehumidifier works fine
for this purpose - cheaper and a lot less work. Luckily my main drain
goes through the cellar, so mine is plumbed in for a plug-in-and-
forget solution.

Cheers!
