December 10, 20214 yr greetings. in our basement we have a structural opening for a sliding door. it's a 250mm reinforced concrete insulated slab. long story short, I need to raise the floor level of the structural opening 13mm from the current level so that the sliding door is at the correct height for the level threshold from the FFL. Can I lay 13mm of concrete (I guess I'd have to get small aggregate pieces) or will that simply not be strong enough to take the weight of triple glazed 2.5m sliding doors? how else could I raise floor level of the opening 13mm? I asked the window company if they could simply use packers and they said no.
