Thin sub base material
Have you any fixings that will work in a 65mm thick precast plate?
I am trying to design temporary works to hold a twin wall system in place until the concrete core can be poured and I am looking at fixing the outer wall to a steel beam to hold it in place without propping. Its a temporary situation only.

This would at least give you a typical indication of load resistances. If your loads are lower the HUS4-8 does

Sorry I hadn't finished but on the uploaded document it does have data for fixing into hollow core slabs with a web thickness between 30 and 35mm with concrete strength from uncracked C30/37
