Retro fitting overflow drain and auto fill in swimming pool

That was a hard couple of hours

It’s very important to have an overflow drain the rainfall here can be very intense,combining it with an auto fill system will save ongoing hasel.
I’ve been putting this off for months but it has given me chance to check the strength of the concrete. I found the top 5 cm softer from the troweling bringing cement and sand to the surface, but further into the cut I found everything was sound. Very happy.
Next I will cement cement in the pvc pipe and reface with tiles.
