Raising + Levelling floor?

[nrawlins]

Hi,

I have a hall floor which is a total of 8m2 which needs raising and levelling between 5-40mm in total.

Some area's not much is 40mm and other are from around 5mm and some about 10mm etc..


I wanted the most cost affective method of raising and levelling it.

I have looked at the Wickes levelling compound but this would be expensive to use this for the whole depth and area - about £500

I thought about putting a concrete mix down but not sure if this would crack as the depth wouldn't be much in some area's.

Does anyone have some advice on this please?

Thanks!

Mix your own floor screed, 1:3 or 1:4.5 ratio of cement to sharp sand. It may be applied onto a solid in-situ concrete. However, the minimum thickness that you should use is 40mm.
