hookline99 · 2009-12-17 14:53:18

I am in the prosess of having a single story extension added.The builder has put in radon barrior instead of dpc above the window lintles is this ok? Also is it struchurly ok to do this if there is only 1 corse of blocks above the lintle then the wall plate would the weight of the roof push the blocks of the radon barrior

Its fine. When a radon barrier is used you don't need a DPC because it acts as both a barrier and DPC.
