Filling gap between concrete floor and wall

[Ewaf]

Hi,

Never knew there was a DIY area to the forums, glad I spotted it!

We had some old french doors removed and the gap widened, and then some new bifolds put into the lounge. As such we now have this gap between the concrete floor and the external wall/bifolds where the cavity was. It's not all the way across, where the old french doors were the concrete floor goes all the way to the bifolds.



What's the best way to fill this gap in ahead of underlay/carpet going down? It's about 5-6 inches deep and I would say 2 metres across. Will some quick mix concrete stuff work?

Thanks in advance!

Concrete will be fine.

Concrete or Self leveling compound...there's a few different products I believe

Schonox latex, concrete will just crumble there’s not enough mass to keep it together, think potholes

See link, you can probably find it less expensive but that’s the stuff. It can feather down to almost nothing without breaking up. We use it to fill the dips in badly laid screed before flooring.
