Help Please! Floor problems

Hello, I renovating my house, and I noticed that a section of the wall and skirting near the front door was a little damp.
The front door is to be changed soon so removed the reveal and saw cavity blocked, I've taken bricks out and cleaned it out. However where the carpet grips have been nailed down the top floor 'layer' is cracked and loose.

Its a concrete floor, with a top layer of about 11mm thick. I dont know what it is or how best to repair or replace this top layer.

I dont think there is an undlaying damp problem with the floor but I cant be positive, under the top layer there was a bitumin paper which I assume was a damp prevention measure, so I dont know if there is a DPM under the concrete floor.

I need to repair a 6inch wide section asap by the front door so it is at the correct level for an oak threshold strip as the door been replaced very shortly.

thank you

Some self leveling compound should sort you out. http://www.wickes.co.uk/Special-Mortars/Latex-Floor-Levelling-Compound/invt/154441?WT.srch=1&WT.mc_id=GOOGLEBASE

Thanks for the advice.

Just wondering, to try and ensure that damp doesnt come up through the floor, if I paint on the liquid DPM paint Ive seen in wickes onto the floor.

Should I paint it on then lay the self leveling compound or paint it on the top of the compound?

Thanks,
