Afternoon All,
I have an Edwardian Terrace house that I am looking to replace the ground floor of as it is like the surface of the moon! After doing some investigation it is a 60mm concrete slab laid over a mix of fly ash and demolition waste and it is also making the house quite cold, so it's time for it to go.
I am looking to lay 100mm Type 1, 25mm sand, DPM (with upstand), 100mm Celotex, second membrane layer and a 75mm screed on top. The area is 56m2 and digging down 300mm, the area covers three rooms (dining room, lounge and a very long skinny kitchen) I do have a builder lined up to do this but my confidence in that they will actually turn up is getting shaky (due to start in July) as they have gone quiet. As a result, the back up plan is to do the work myself but I have a contact that can lay and finish Agila as the final layer. Would it be better to retrofit a suspended timber floor instead? There is an air brick just slightly below ground level, which makes me think the original floor may have been suspended. The area I live in was hit by a major flood in 1965, so it may have been removed as part of recovering the building.
What I would like to know is how long it would take to hand dig the floor (mini diggers are not an option) and if it would be possible to lay it in sections (room at a time basically) with an appropriate barrier. The concrete has already had to be broken in order to lay an electrical conduit and it breaks up without too much bother.
Any info, tips etc will be greatly appreciated.
Kind regards
