    position of walls on concrete trenchfill

    How important is it to get the wall dead centre? I've got 600mm width by about 600 deep in clay but there's a bit of a banana shape to it that I only eally noticed after the concrete had gone in TBH and the wall gets to about 7cm from the edge in the middle, It's single storey & fairly...

    Neighbours extension foundations (or lack of)

    Noseall's not offered a solution has he? Back I go to the road drill. Favourite new tool. Good workout and the neighbours LOVE it.

    Neighbours extension foundations (or lack of)

    BCO had a nose and said 'dig it in bays and fill with concrete' so top marks there John! Raises a question about detailing though - the concrete fill will have to come basically up to ground level to properly support the wall won't it? But there's supposed to be a layer of hardcore, sand, DPM...

    Neighbours extension foundations (or lack of)

    What do you reckon the BCO's likely to suggest? Also: I stuck a crowbar in till it hit something solid. 30cm from the rendered face of the wall. I guess they cut a trench and filled that side then?

    Neighbours extension foundations (or lack of)

    It's a whole single storey kitchen extension - seems to be building regs free - I think they decided it was PD and then must have decided that meant they didn't need building regs either. I've not actually asked them...

    Neighbours extension foundations (or lack of)

    Party wall stuff's all sorted already. They're right nice the neighbours. bit worried the BCO coming to visit Tuesday to have a commencement look about will have some expensive ideas for all of us. Any idea what underpinning a 3m wall is likely to cost? Not too much, right? What do you mean...

    Neighbours extension foundations (or lack of)

    The neighbours four year old extension starts on top of our shared (probably Victorian) garden wall. I've been digging a hole to see how far down it goes down / whether they underpinned it at all and... there's nothing there. It stops one course below ground level. I'm supposed to be building...

    SCREED / PowerFloat question

    I've got a question about screed. Can it be powerfloated for a nice finish and if so how long after sticking it down do you have at it? Don't say 'you should get a professional in'. I know I should get a professional in but that would be a lot less interesting. Also, on the same subject -...

    Old manhole under new slab

    Simple question for you: I'm moving an inspection chamber out of the footprint of a new extension but what do I do with the old inspection chamber (not connected to any drains any more)? It's only 65cm deep but bang in the middle of where the new slab is going. Do I just knock the top few...

    Rebuilding a shoddy lean-to - advice needed!

    First post and all... Attached is a picture of the lean-to attached to my bedroom. It's got a solid concrete floor above the crawl space which is held up by hopes, dreams and a lot of rotted wood, a double glazed door that sweats, a roof with no insulation and solid, cold walls. I was after...
