Hi, some questions please on fixing a timber sole plate on to 100mm thick concrete block on top of dpc/dpm; ground floor (Timber frame wall panels will go on top of sole plate and bottom rail of the wall panels are 89x38mm cls timber)
Recommendations please for common sizes of sole plate for this? - I have heard/read various to use 25x100mm or 22x100 or 22x88mm.
I have read fix at 600mm centres using masonry nail, I have also read you can use expanding bolts. Can you advise on use of bolts and any good make of same as if they are stronger and get good recommendation then would prefer to use same if it gives me a stronger base. I have read I would need to seal the bigger hole this type of fixing makes in dpc and my next question would be how you do that?
What do you use to preserve soleplate – do you buy treated/tanalised timber or are there special preservatives you self treat timber with.
Thanks in advance !
