Can this be used as a pond liner? I have a lot left over from a raised bed build and would like to use the rest for a pond if possible.

I don’t think so it’s not flexible as if it was a rubber type of sheet you can put it down and spread it when you fill it up with water it will sit tight against the wall in between grooves and things like that to make it water tight for you understand what I’m saying, it will be flexible good luck

Can I leave a membrane cover on existing wood/felt roof & then putting new wood/felt on top of membrane,can I leave it on under wood or not.

I personally believe when replacing Dom you should always remove old, treat surface and re seal before replacing the dpm. There could be a risk of sweating/ condensation if the dpm placed over existing dpm. The question is why are you replacing it, do you know where the leek is, where is the ingess coming from.

Would it be apropriate to place under the asbestos cement sheets of the roof of my garage to prevent water drops inside and would it cope with hot wea

Difficult to say exactly without seeing your garage roof but it likely would be ok, it’s a plastic impermeable barrier so will not let water droplets through. It’ll be fine in the summer heat as long as not in direct sunlight for entendres period(several years)

Really good quality

Really thick, heavy duty membrane. Incredible value for the size you get. Easy to use, I laid a stone hardcore layer, then a sand top coat to level, then put the membrane down, then a light sand layer before laying slabs on top, for my shed. Stops moisture coming up through the slabs and also prevents weeds.
