Replacing suspended ground floor wooden floor with concrete suspended floor

[Deanooooooo]

Hi

Advice needed please.

I have a 3 bed semi detached house.
It has a suspended wooden floor with a crawl space underneath. No insulation so is cold.
The washing machine in the kitchen shakes itself to bits, I have screwed 18mm ply underneath the washing machine and fridge freezer which has helped a bit.
Ideally would like a solid floor all down stairs, don't like the noise of wooden floors.
Is it possible to replace it with a suspended concreate floor, would this be comparable to a solid concrete floor. Can this be retro fitted to a 1970s property.

Thanks

How big is the void? Bigger than about 600mm and you will eventually run into settlement problems as compressing that much hardcore will likely end with it dropping. I guess you could use a solid void filler such as Fillmaster from Jablite, that would also avoid exerting any pressure on the inner skin if that was an issue.

Hi the void is about a meter, could I use concrete block and concrete joists as in new construction? Don't want to have any dropping!

would the floor be solid with jablite would there be deflection / bounce. Would is support weight well. Would it be quieter than a suspended wooden floor?

And does building control have to sign off the work?


Thanks for your reply.

As above.

OP, do you have any idea of how much your proposition could cost you? For what? Are there any exceptional circumstances?

A suspended concrete floor is not worth thinking about
in a residence.

Retro Block & Beam are likewise simply not on.

Whats wrong with carpet outside the kitchen?
