Putting a new pond liner in for someone probably PVC type and need to
stick it up and over surrounding cemented wall which has paving slabs
on top ...... I will then over cap with new top slabs etc.
What is the best adhesive to use ? I plan to insert the liner over the
old for a bit more protection ..... Is this a good idea ? Any tips
would be most helpful Cheers

As Bob says, PVC will crack in time.............not long. If you go for it,
use .5mm or .8mm thickness. Preferred material is Butyl rubber.
