Hello,
I have a house that has suffered movement. This is believed to be long standing and non-progressive however to improve the structural stability the report recommended;
• Inspect the cavity wall ties.
• Strap the side elevation wall to the first floor timber joists at 0.8m centres maximum, or provide helical threaded bars which would achieve the same objective.
• Attach the side elevation wall to the internal cross wall by the introduction of right angled “Bat” straps with 600mm legs, which should be installed at 600mm centres vertically above and below the first floor level.
The side elevation is having the internal plaster removed (due to cracking) and the floorboards will be coming up (need levelling) so access should not be a major issue. Am I wrong to think this is a job a diyer can complete and if so could someone please give me advice to help me do it right.
I have found this on another thread, "Fit 30x5 restraint straps notched over 3 joists with noggins half the depth of joists below straps. Straps max 0.8m centres". Is this what I would need to do to strap the wall to the joists?
How would I fix the straps to the walls, I see examples where this is done between the leafs, not sure if this is for new build only??
I can’t seem to find any right angled straps with 2 No. 600mm legs. Can someone point me towards a suitable part please?
If I do this myself I intend to bring the structural engineer in to inspect the work.
Thank you for reading and I hope this makes sense. All help is definitely appreciated. Thank you.
Pat.
