First post - be gentle. Have just begun rennovations on a small terraced house. We have penetrating damp in the floors in the kitchen. There are quarry tiles in place and after having lifted a few the screed is very weak and damp. I have dug out a bit and about 4 inches down is soil. I am obviously going to have to dig the lot out and put a membrane in and concrete on top. Any recommendations on how far to go down? Do I need to put in and compact scalpings or roadstone or hardcore? How deep? Sand blind on top of that then DPM? Concrete on top? - how thick? Do I need a screed or can I just use concrete and then some self leveling compound. Thanks in advance. | ||

Its been there for decades it wont settle any more.Take it down 150mm from ffl.100mm concrete and 50mm screed is the minimum but... better is take it down 200mm and put in 50mm insulation(celotex et al)then membrane then as above. better still is 100mm insulation etc. | ||

You can,and chuck on some self leveler.I like to do things right and a bit over the top to be honest but screed will last years and Ive seen self leveler come up on many occasions and so many pours that are not level or the right height and result in too much for the leveler or not enough cover. But if you want a quick cheap and cheerful solid floor(selling/developing the house)then you can take it down to 100mm chuck in a membrane and pour.If your concrete finishing is good you may even get away without S.L if tiling/laminating on top. | ||

Don't want to bodge it and scarper by any means. The floor is for a small kitchen and downstairs WC all of which will be tiled. Want the floor to be safe and dry for whoever buys the house. | ||

Suggest you insulate with celotex or something cheap - try seconds&co.co.uk or even ebay for small area- even if it just let's you say to the buyer we laid new floor and insulation....for the sake of £100 for the insulation(?) what might you get back??? | ||
