Hi guys,
I am in need of a 'one-sided' membrane.
Basically, something like a bad damp proofing membrane. Allow me to explain:
A membrane which will allow water to pass through one-way (at a fast rate - this is where it differs from the damp proof membrane you can buy in the diy shop). But not allow water to pass back through the other side.
Any ideas? Info? Advice?
cheers!
