Some advice please!
I am having a set of folding doors fitted 5M width.
The builders have positioned the steel etc and we agreed that to keep costs down I would sort out the cavity threshold detail.
The folding door chap has now been round and said that the dpc will need to be dropped by half a course in order to get a flush rebate/floor level.
I currently have the 5M opening with wall removed down to dpc with the existing screed being approx an inch above dpc.
Any ideas on the correct method to create this new dpc level and the best way of filling the cavity?
Would it be best if I removed a course of bricks from both the inner and outer leaf and rebuilt the outer leaf with brick slips (half brick height) and then lay extra wide dpc on this new outer leaf and form a trough and bring the wide dpc back up towards the inner leaf and up to the screed height and fill with concrete?
If this was the best method would the door frame then be screwed through the dpc and if so is that ok?
Any advise appreciated.
