Thanks for all the posts

Bit worried about the fella - with knowledge of decaying bodies :-)

To answer some of the questions them, its quite cramped down there and
musty. If the floor doesn't breathe - it will end up stinking like any
textile I've stored down there even in plastic bags. It does get some
ventilation but not enough.

I don't want the dirt and hasle of laying concrete as access is only
through the house. Should have done this before I did teh house up.
Stupid!!

But the extending the mat idea to a long role of perforated "grid
like" will give me acess to all the cellar and I can store stuff on it
so it doesn't get damp.

Its just finding the right material


Solution 1:
4-6 mil poly sheeting on top of existing floor.
1/2 plywood on top of that.
A dehumidifier set at about 55-60% RH.


Solution 2:
Break out old concrete in areas where damaged (preferably in a nice even
square or rectangular shape).
Dig out some dirt (8-10" deep) and level hole bottom.
3-4" of pea gravel or 3/4" stone (whichever is cheapest in your area) tamped
down.
2" Syrofoam SM Type 2 cut to fit
4-6 mil poly sheeting or other rubber/bituminous membrane.
3-4" 2500psi or better concrete (with rebar mesh if required by code)
A dehumidifier set at about 55-60% RH.
