    Hi all,

    I just purchsed my first property (yay for me ) and so i am now looking at what needs to be done.

    Its a split level brick house, with the bottom level being a large rumpus room and store room. The rumpus is fully finished off (ie a tiled slab and plaster walls etc) but the storage room is the original dirt and sandstone (and is behind the rumpus walls). With it being sandstone which is porous there is a degree of moisture (actually after a heavy and constand rain for a couple of days, there was water seeping from the stone) and that damp sort of smell. Theres 3 windows in the area which were open so some of the water could have been from those too but i think that stone is still an issue.

    So if i was to have this concreted over and turn it into a big wine cellar, would that get rid of the water and damp? My thinking is that since most places are a concrete slab over dirt and rock, this wouldnt be any different but i thought i would seek what everyone here thinks. Or alternatively is there another way to "seal" sandstone?

    Or do i need to put in some "active" drainage and direct the water into a proper drain?

    Anyway any thoughts would be cool :) Cheers

    Hi Darktrooper, I had a similar situation on a reno we completed not too long ago. A triple garage (very old) with a sandstone floor, very uneven and bits missing, etc. My guys leveled the floor with gravel and then poured the slab on top (mesh and drainage included). The gravel helps drain the water that does not get “captured” by the normal drain and also helps with moisture.  I hope this helps.

     

    Happy Investing
