The 2.1m lintel x 215 x 100mm will sit on the corner block work of the house and on the retaining wall to carry the last 3 beams for the patio

Good evening Gents, Just a quick update on what has been said by the SE I contacted the block and beam supplier in bristol and asked about external use and for a copy of the data sheet.. they informed me that external use for beam and block is fine. The SE originally way over specked the design for the north elevation balcony (in the pic where the brickie is) he wanted 8" steels to carry the block and beam at 2.1m long... wasn't happy with this as it would of meant having a small step from east side to north side... so i decided to change the design.. on the east side we have 4.2 b&b which will sit on the external skin of the house sit on the retaining wall and ive also built a block on flat wall at 4m to carry the load all agreed and happy with the SE... The only thing he wanted was an 8" lintel to carry the last 3 beams.. i will run a dpc tray for the beams sitting on the external skin of the house blockwork for the north facing balcony we have used 6" galvanised i beams which will now carry a timber frame and have composite on top.. we have built to supports into the house which are sitting on padstones.. thank you for the feedback gents

yes, i will as soon as i hear anything back... im still waiting but ive taken delivery of 17 beams today so im hoping its a yes haha

It’s getting there.. we had to move around 1600t to begin with.. went for the concrete retaining wall and pretty happy tbh.. the joists and scaffold come first week of January so all systems go..

That’s a very in-depth reply and way above my limited knowledge but I think I get it 🙈 thank you

Thank you for the replies.. I’ve added another picture.. this span is about 1.5m.. I’m having a galvanised H beam frame being fabricated which will carry the beams from the house. as the first image.. I’m thinking same again as to tie into to the house, the retaining wall will carry the bull of the load plus I’ve dug a footing to build a small wall block on flat to carry the end of the beam.. I’m looking at 4.2m beams.. this will then become only a patio area no storage.. I was thinking of a slurry screed and to bitumen all external parts of the beams before slabbing on top?? the other option is timber and composite decking but I don’t really like this idea? What are your thoughts? I’ll be going to the SE first week of January with my idea

Thank you mr punter.. was a bit of a struggle but we are getting there. It is up to first floor level currently waiting on joists and scaffold after the new year so trying to sort this beam and block idea asap im only looking at using 4.2m beams build another small wall to carry the end of the beams.. the architect seems to think it will be fine but wants me to check with the enginner. I was just thinking of using a cement wash over the top and screed and patio slab on top.. but if anyone has any better ideas I’m open to listen?

Hello all,, just a quick question before I send it off to the enginner, has anybody used beam and block for external use? as you can see by the pictures I have a retaining wall which is set back from the house.. I’m looking to bring a block and beam from the outer skin of the house and sit on a frame/retaining wall and this use this base as our patio screed over the top and then slab.. has anyone used beam and block for external use before? What I was thinking of doing is bitumen all external parts of the beam before cladding of some sort to keep it weather proof any replies would be appreciated

thank you for the reply.. i contacted BC and they are happy.. bloody builders trying to save me money haha

all rectified today, they supplied another barrier and went on top of the slab and everything taped as should be.. the flooding comment was tongue and cheek, basically ive got a liner for a swimming pool on my slab holding water as ffl is 195mm above the finished slab

Hello all, I thought i was on top of everything but i think ive come across an issue.. my slab was poured last week to the spec but ive noticed that the radon barrier has not been taped at the joints coming over the brick work.. so this tells me it has not been taped at all throughout the slab. i wasnt on site to oversee this i can still add a new membrane but that would be over the top of the slab which would be a hassle for flooding but something i might get peace of mind over? what are the thoughts of the self build world on this please
