Hi people,
Just signed up to post this topic, but I actually hit the site with fair frequency given all the DIY I do.
I have a cellar that is 69" high from floor to ceiling, with a window to the front of the house. I have up-rooted a paving slab and dug down to find the bottom of my foundations - 17.5" below the floor - sat on dense mud / clay. The wall is (or should be) double brick with a cavity. The last two layers of the foundation brick are stepped out by half a brick, and I presume don't have a cavity.
I'm looking at converting this fully into a cellar that meets regs to be considered habitable.
It has 2 external walls, 2 internal walls (these walls contain the staircase in an old 2-up 2-down terrace), and 1 party wall. I'm sure of the 2 external walls being cavity and 1 of the internal walls being single brick. The other internal wall and party wall I've no idea about.
I want to achieve at least a 2m clearance, meaning I've got to go down another 9-10", this doesn't include space for the floor itself. I've no idea what the floor should be comprised of or what regs it needs to meet. I immediately thought of a floating concrete solution, but have no idea about insulation.
When it rains, the floor also gets rising damp coming through the stone. I have had one small puddle of standing water before on a really bad day, so I presume the tanking is going to need some active drainage.
I'm looking for advice on the flooring, whether foundation pinning is required / what circumstances it is required in, and tanking options for the damp walls (not wet to touch, but definitely damp, I think rising).
Thanks in advance for any/all replies. I'm in Macclesfield in case anyone knows of a local specialist worth contacting.
