..now is the time to put in the liner. Does anybody have any views on using a dry mix cement instead of sand between the liner and the soil. I have seen web sites on lining a liner with cement so presumably the cement does not do any harm to the material but I have not been able to find any information on using dry mix instead of sand.
well, knowing how dry mix cement works, you would be making a solid form, once the liner is in and filled with water, give a few months and you will have a permanent pool which will be more difficult to get rid of should you ever wish to do so.
what is your intention?
leaving it there for ever and ever... :D
