We are doing wet UFH on suspended floors with very strong timber joists (9 x 3in at approx. 400mm centres, max span 4.8m). We are setting the pipes between the joists on a 45mm thick PIR base and pug mix (8:1 sharp sand: cement) between and around the pipes, as commonly used. I understand the pug mix is usually mixed and laid dry but my builder would like to lay it wet, in fact he has already started and it looks ok.
Is there any disadvantage or problem laying the pug mix wet?
