Another day, another topic....Today we're fixing our timber soleplate to our concrete block wall. We already ascertained last week that the blockwork wall was not level enough at various points. After reading stuff about packing underneath the soleplate regarding potential condensation problems, and difficulty in filling under the packed plate to achieve air tightness, i decided to get the brickie back to bed the soleplate in mortar. It's done and is level enough running around the perimeter, 18 m x 6.5 m. But it's off level running across the 145 mm of soleplate for a length of about 10m running down one long side. I'm a little upset by this, as not only is my internal FFL affected, but we're still looking at having to pack the sole plate !.......any ideas community?
