Thread: Pool Waterfall

I finished my pool 2 years ago with extra pipework so that the filtered water flowed via the waterfall by changing a valve. The pool cost more than originally budgeted , so the waterfall had to wait . It’s been a hole in the garden around the pool for too long, so I finally finished it over Xmas.

I had some gal steel top hat section from old my shed’s purlins so used them for vertical supports concreted into the ground (1 at rear and 4 for the walls). I also used some old secondhand internal gal steel studs from a wall they pulled down at work for the wall horizontals, which in turn supported some more top hat sections forming the cantilever. I then covered it all with bird wire I had in the shed.

I covered all the wire with cans of expanding foam - 40 of them. I used small ones as I found I got more out of 2 of them than 1 larger can of equivalent size (and the small ones were on special). I found I had to use one can at a time letting the foam set before using the next can, or it tended to peel off the wire.

The pipework comes from behind up the rear vertical top hat then via a couple of 90 degree bends into a plastic container cast into the foam (inside the cave at the top). I coated all the foam with charcoal coloured render, with Bondcrete to help bonding, and Silasec as a waterproofing agent. Found the best way was throwing it on then wiping it with a sponge - doing the rendering under the cantilever was a bitch .

You can even get behind the waterfall whilst sitting in the seating area, a prerequisite of my son. I also added a few more blue lights in the garden to highlight the waterfall (that are pink to start with ) at night.

Cheers
