HI Everyone
I placed my spa on my concrete pad today and got out a level and found the concreter has a slight fall back to my retaining wall. He was told I wanted it level for a spa or the slightest slop ever for drainage towards the grass. Anyway the ******** has put a slight fall back towards my retaining wall....... hard to get good help. Anyways one way is pretty level and not much out but the other way I can lift the level about 8mm before it become level. The spa weights 200kg empty and takes 950 litres full so all up with people could be 1.5 tonnes. Should I worry about the unlevelness. I was going to shim it with Masonite but was thinking this could just end up ripping the frame apart due to weight. Am I better of taking my chance and leaving it or shimming it?
/Thanks
