vik2001 Posted April 6, 2024 Posted April 6, 2024 (edited) Can you lay blockwork on top of block and beam floor to create a wall partition, they will not be load bearing just on single storey with flat roof aboce. I want to subdivided the floor area into 3 separate rooms. Edited April 6, 2024 by vik2001
Mr Punter Posted April 6, 2024 Posted April 6, 2024 You will be OK with thermalites. You can't rest the roof joists on them though. 1
Andehh Posted April 6, 2024 Posted April 6, 2024 Yes you can, we have full block walls internally throughout on block and beam. Double check with SE to be extra safe. We didn't use thermalite.

nod Posted April 6, 2024 Posted April 6, 2024 No Anything other than a stud wall needs a sleeper wall below 1
Mr Punter Posted April 6, 2024 Posted April 6, 2024 I have done a feature brickwork fireplace directly off beam and block. The floor designer specified multiple beams for that section - something like 10 together. We could have done extra footings for similar cost.
Canski Posted April 6, 2024 Posted April 6, 2024 I wouldn't unless it was calculated at design stage. I have built non load bearing walls off double or treble beams but the loads were designed in.
Andehh Posted April 6, 2024 Posted April 6, 2024 (edited) The floor.... You can have blocks on a Block and beam flooring, though check with your SE. Ours ceilings are also between 3.2 and 4.2m high, though only a structural spine wall sits on the subwall/where the beams sit it. All spec'd from design stages. Edited April 6, 2024 by Andehh
Andehh Posted April 6, 2024 Posted April 6, 2024 (edited) We did have very very big beams though!!! With only a single subwall down the middle. Ground crews joked we were building a skyscraper, they hadn't seen beams as big in a house. Edited April 6, 2024 by Andehh 1
Iceverge Posted April 6, 2024 Posted April 6, 2024 If you use hollowcore concrete planks blocks shouldn't be much of an issue.
vik2001 Posted April 6, 2024 Author Posted April 6, 2024 Have a question on 1 side of the wall the builder hasn't built a inner leaf, he's using the concrete beam to act as the inner leaf to build the inner wall off. Is this OK to do?

Is this OK to do? If the beam is supported along its length you will be fine, if it only supported at the ends you are not at all fine.
Canski Posted April 6, 2024 Posted April 6, 2024 If there’s a cavity in that then the inner skin looks like it will be resting on the block. That’s a no no.
vik2001 Posted April 6, 2024 Author Posted April 6, 2024 This will be a cavity wall and the beam.is only supported at the ends, there is nothing supporting it below. It's a single storey wall 3m in length. What should I tell the builder?
Andehh Posted April 7, 2024 Posted April 7, 2024 (edited) Show him my picture above, though maybe not this thread (avoid pissing him off by showing how much you distrust his work...) and ask him why 'my' picture has the beams sitting on the inner leaf and a cavity built out from them. Ill try and get you a batter picture. Edit... That being said, I don't think it's fixable without breaking out the brick wall and laying it again further out.... If your foundations are wide enough to do so. I'm also not sure what the 'issue' is with what he did other then a smaller cavity depth cavity (work hard to keep it cleaned of mortar dropping in) Edited April 7, 2024 by Andehh
Andehh Posted April 7, 2024 Posted April 7, 2024 (edited) For the edges I remember them laying a half brick down on the outside, then the block was supported by the beam on the inside and this half brick in the outside. Then again same done between the beams around the outside. I guess technically this means my inner cavity walls are sitting on the blocks, but these blocks are sitting on a half brick for the core of the strength. Sort of see them in this pic here.

Mr Punter Posted April 7, 2024 Posted April 7, 2024 I would arrange to meet with Building Control on site. Let them break the news to the "builder".

vik2001 Posted April 7, 2024 Author Posted April 7, 2024 Thanks I will get BC to check at dpc /oversite stage which is when thr next inspection is due. Thr builder is calling BC as he organised them it'd a privste inspector. Is it true that pictures are sent to BC as well In Some cases or do they have to come out to site, just want to make sure builder doesn't send pics which I've heard some people say can happen.
Mr Punter Posted April 7, 2024 Posted April 7, 2024 They will sometimes just want pictures but if you request a quick visit they should agree to it. I assume they inspected the foundation trenches?
vik2001 Posted April 7, 2024 Author Posted April 7, 2024 Yea the foundation trenches was passed by them.
