From foundation to wall level

[RichS]

A question for anyone who has used an insulated foundation and then built in ICF.

 

I assume, as I haven't got my foundation design drawings yet, that the insulated foundation will have 100mm wide perimeter upstand, but Polarwall use an 80/150/80mm construction.

So where the wall meets the slab there will be a 20mm difference in the external wall line.

How have people overcome this obstacle??

You can use different thickness of board with Polarwall, so you could easily have a 100mm board on the outside. Maybe give Alan a call as I'm sure he'd be able to help

Thanks Vijay, I think there's only the two of us using ICF

We used econekt who do both foundations and walls so the 2 lock together.  WE have 250mm thick outer insulation, 150mm concrete and 50mm internal so 450 overall before finishes!  The econekt foundation upstand is adjusted as appropriate.

Hi @le-cerveau. Just had a look at Econekt site. It mentions that it pours it's floor slabs at 250mm, is that correct?? Seems a bit like overkill to me but perhaps there is some reason.
