    Removing concrete

    It's about 3m wide and about 1m deep. Just googled for a floor cutting saw and it looks like it's worth further investigation - thanks!

    Removing concrete

    Hi, I'm doing a cellar conversion and I need to remove a "slice" of concrete from the floor. I'll try to explain. The original cellar construction had a sloping "floor" to take account of the house being on the side of a hill. I've tried to show here: Later, someone came along and...

    How it is now

    How it is now: someone has built a breeze-block wall, put down a polythene sheet, and back-filled with concrete to give a raised, flat floor.
  4. How I want it

    How I want it

    How I want it: lower the raised section a bit, so there will be a little step in it. Note: not going down into the original construction.

    Moving consumer unit

    Thanks for the replies! Crimping may be the only viable option from those three for extending the cables - but at least there IS an option and I don't have to rewire the whole house. Yes, I thought it would be expensive but thanks for the warning. (I also have to get the gas meter moved in...

    Running pipes DOWN to radiator

    That looks just the job - thanks. That was roughly my thinking, although I didn't realise they were available as a neat single unit like that. And it's OK to use one of those and have the pipes-coming-down arrangement? Ta, Mark

    Moving consumer unit

    Hi all, My electricity meter and consumer unit (horrible old fuse box which is already over-populated with at least one fuse supplying two rings) are currently in a cupboard just off the kitchen (effectively the cupboard under the stairs). I want to open this cupboard out, and don't want the...

    Running pipes DOWN to radiator

    Hi folks, As part of my cellar conversion I need to install a radiator. Central heating is pumped, with normal two-pipe feed and return arrangement. The house is on a hill and is a funny split-level arrangement, meaning that even though it's in the cellar, the new radiator will be only a...

    Plastic pipe for new radiator?

    Hi, I'm doing a cellar conversion, which involves adding a new radiator to my central heating system (15mm copper pipe, feed and return). The cellar is going to have insulating plasterboard along a couple of walls, including the wall where the radiator will go. Pipes have to come down from...

    Synthaprufe vs Wickes "Liquid Damp Proof Membrane"

    That's a bit of a pain, as that's exactly the wall I wanted the radiator on... perfect place for several reasons. Oh well, better to know now than when the screws rust and it comes crashing off the wall in two years' time, I suppose..! Thanks!

    Synthaprufe vs Wickes "Liquid Damp Proof Membrane"

    Ah, that's interesting. So I can't drill through it? How do I mount radiators and other heavy things? Ta, Mark

    Holes for central heating pipes

    Thanks very much - I understand now. For the benefit of anyone else who may be confused, the 7%-25% business means that notches must be between 7% and 25% of the length of the joist from the support - i.e. not right at either end, but not in the middle either. Are plastic pipes easier to...

    Holes for central heating pipes

    Thanks very much for the replies! And do I have to use plastic (not metal) pipes? I was going to use copper, that's what's there now. Sorry, I don't understand what this means. Span between the joists, I presume? So if I go through 20 joists) I must notch at least two and not more than 5...

    Holes for central heating pipes

    Hi, As part of a cellar conversion I need to move a run of central heating pipe from its current location just under the ceiling in the cellar, to within the ceiling above the cellar (below the dining room). (Going to take the opportunity to drain out the system and add fernox, as I've only...

    Synthaprufe vs Wickes "Liquid Damp Proof Membrane"

    Hi, Background in case you're interested: I want to convert my cellar into a usable living space (home cinema, no need to add a window, which is handy). One (cavity) wall of the cellar is up against soil. (The other three walls are "internal" - one against my neighbour's cellar and two...
