RSJ into upstand cutout?

[junglejim]

The upstand around our slab is cut for RSJ to fit into at slab level. I’m wondering how best to finish the exterior around this as will be closer to ground level and below the cladding. Presumably it could somehow be sand cement rendered?

 Thanks

You can shot fire a piece of SS mesh to it Then render over it

Thanks, that’s useful. The side facing outwards is the ‘I’ shape so not a face. I’m thinking of insulating, adding noggins and then osb with dpc over but wondering if I’m better off covering in render board and extending down to overlap the slab?

Cement board is perfect for render 

But you still need mesh or a fibre mesh on top of the board

Slightly concerned this could be a way for moisture to ingress (around edges of the RSJ) any tips on sealing? Considering expanding foam + mortar to fill gaps.

I would use a PU glue

Figured a drawing would be useful as still a bit unsure of the best way to finish this.

 Thanks for all the tips.

Here’s a photo of how it is currently. Will obviously need to dig out the ground as well.

I’m wondering if there’s any mileage in filling the base of the RSJ  with mortar? But probably not ideal from a cold bridging perspective.

What is on the drawings? I would of expected pir infill of the rsj before the osb.
