I personally have an in ground pool but I am writing tonight to request help and opinions for my neighborhood fountain. In my subdivision (small with 20 homes) we have a VERY large, round pool basin that holds a large tiered shaped (about 9 feet tall) fountain made of concrete bowls that water cascades down 3 or 4 levels into the main pool. The main pool is round and about 6'-8' accross (diameter). It is stack stone around the wall (about 3' tall). It looks like it was just stack stone in a circle and then sealed. It leaked so it was rebuilt by some company about 3 years ago. They sprayed or painted some type of material that was like black tar and had a blue rubbery paint on top of it. It was okay the first year but cracked around the conduit in the floor and I fixed that. We had to close the fountain for the last 1 1/2 years because of the water ban (drought in GA). Being dry the last 18 months has probably increased the deteriation of the walls and floor because now the tar-like rubbery walls will peel really easy and are very brittle. We filled it with water and opened back up today and it is leaking everywhere. Probably 1/2 inch an hour coming through the stack stones over 180 degrees around the whole fountain.
I need help to figure out how to best renovate it. In the floor it has power for the pump and power for the SAM lights plus a 3/4" water line. The wire is in conduit sealed in the floor and comes out under the concrete fountain part above water.
My two ideas so far are:
1) To get a pool guy to measure it for a vinyl liner with some sleve type piece to allow for the wiring and the water line to enter the pool. Like a snorkel?
2) Get a guy who blows gunite pools to stop by when doing a pool near by to blow out this fountain. My concern with this is that gunite probably won't stick well to the rubbery/tar walls and floor with out removing that crud first and I don't know how to get that stuff off. That could be a crazy project by its self!!
Both options require us to move the heavy fountain out of the base pool prior to resurfacing it.
Any of the members on TFP have any great experience to share with something like this? All ideas are greatly appreciated!!!
