Yes there is load bearing wall below and a steel post to the chimney side of this beam. It has all been very stressful. all I have ever asked for was a single beam (to avoid fab costs) because it can come in through the new window opening. Such a shame as this should have been quite simple but...

Thanks. Surely the beam a is where one end will be and other on a fabricated steel post? Bricks are white engineering bricks. I'll try and upload other data pages.

Yes, that is what I have thought. The calculations are from a paid an engineer. It was originally a 5.1m 203x133 with a support post at either end (one in stair wall) I did not want the post and wanted it to span into gable wall as was discussed originally with them. This is the new full length...

Thanks for your replies. I am looking at the calculations given to me for a 6m ridge beam that has come out a 203x203, 46kg and it seems huge to me for a ridge beam. It is a straight forward flat rood loft dormer of aprox 5m and velux type windows in pitched side. I can't see why something so...

Hi, my opinion, if it is of any help is that you will be doing a lot of work for little real benefit. I like the idea but in practice you will have to put the stored stuff on the new door ( so itself will need to be structurally sound to take the added weight) SO.. When you are down there in...

Hi, I'm looking at some calculations for a beam. Is it correct that celotex is listed as 0.25kn/m2 ? Only unsure as it is listing plasterboard and skim at only 0.12kn/m2 and 25mm flooring at 0.13kn/m2 Surely it's not heavier than these two things? Thanks

Thanks again for your advice. Ill see what i can get hold of. Yes the cost and amount of work is going up. Paul

I'm not sure i understand what you had written about the dpm is concrete. is there a typo? I live in Kent just below j5 and j6 of m25 and in reply to your other question - Yes i filled it with cement and ballast a few weeks ago. I also mixed mortar up and filled around the edges where i...

Thanks for reply and appreciate your patience knowing how hard it is without seeing. I dont really understand, if there was only 15mm/20mm of sand and cement screed before, would i not just be doing the same or was it originally too thin too? The concrete slab is not very smooth and has some...

Hi,I'm still doing this as not had much time on it recently and was waiting for the delivery of the f77 I've got the f ball f77 now, arrived today. Two questions Should I prime the concrete first with something ? As I have to get back to the old height of 15mm in screed can I use sand and...

Thanks. I've been here 20 years so far and probably another 2 to 5 more. I will grind some of it flat this weekend and next week. Would you recommend an epoxy concrete to fill the holes back in or would regular sand and cement be ok?
