I've got a 18x32ft in-ground lined pool in the garden (approx 1970s intall, a company called Fernden).
The deep end is 8ft - and for reasons of child safety I'm keen to raise the bottom to a maximum of about 4.5 ft.
I've had a contractor quote the job on site ($ many thousands!), and another contractor give a ball-park estimate at a distance (similar figure to the contactor who saw the site).
Because of not being able to afford the huge sums quoted, I'm thinking about doing the job myself - and I had this idea that maybe I could just pour concrete into the existing lined pool, rather than replacing the liner as the contractors were advising.
Now, I know this is not the conventional way - but surely it wouldn't be too bad? I thought that the new concrete base could be tiled, and that the join between the new tiles and the liner of the existing walls could be siliconed?
The way I see it, when in due course the time comes that the old liner on the walls will need to be replaced, it could be cut where it emerges from the new concrete, and a new liner could then be used for the entire pool, including the new bottom. I might be being naive, but surely there wouldn't be any problem with the old liner remaining in place under the concrete base?
Anyway, that's my idea. I'd really appreciate comments / advice (please be gentle in the comments, even if you feel like doing this ->
thanks a lot!
