Vinyl Liner
Pool with a vinyl liner.
Yes
Afraid not. Vinyl liner pools are built using "concrete receptor coping" into which the deck is poured. It also contains the "bead receptor" that the vinyl liner attaches to. Actually YES it can. You would want to do this during a liner replacement but it can be done. You would have to remove the concrete from around the perimeter of the pool, remove/ replace the "concrete receptor coping" with bead receiver, aluminum extrusion, form/pour a bond beam, then lay your stone. Not really an easy do it yourself job but it can be done.
High concentrations of chlorine can and will destroy a vinyl liner.
You can't
28 or 30 mil
To fix a detached vinyl liner from its spot on an above ground pool, the water will have to be drained from the pool. Then, a marine patch can be placed on the area to re-attach the vinyl to the place where it came apart. Allow this to dry thoroughly before refilling the pool.
