concrete looming!

[matt-shrops]

Good morning all.

After a busy few weeks I now have the 260mm of insulation down ready for the reinforcing mesh and bars then the concrete pour a week on monday. 

To stop the insulation upstand from moving and while the concrete is poured I am considering moving some soil or stones against it. The DPM will be wrapped around the insulation.

What is the best material to use to protect the DPM and insulation from the soil/stone? I have wondered about paving slabs, or some sort of weather proof board? 

 

Ideally once down in will remain in place!

 

And is there a better method of keeping the insulation upstand (200mmx200mm) in place ? It will be stuck down using low expansion foam.

I will upload some photos of my work so far!

Many thanks!!

I wouldn’t have thought it would move if it’s in tight enough, ours was put in round the walls then the base put in and it was tight enough to hold the upstands

MBC held all the upstands in place using giant metal staples to keep the blocks together.

We also used metal staples from kore which we run out of and made our own. I think biggest bit for no movement was the guys who poured the slab, they where concerned for movememt and eps lifting/floating in the concrete and placed concrete very cautious and slow with starting on the main slab before the ring beam. Seemed to work.

This gives you the idea of the staples, we never used a timber batten around outside.
