Hi all. The dig will be 1m deep x 8.2m long x 450mm wide. No pipe work or anything to worry about, a straight forward dig and fill. Concrete required will be 700mm x 8.2m x 450mm. All crap from the hole to be taken away. How much would I be looking at chaps Andy - midlands

My neighbour lives in a detached house whereas mines a semi, so getting them to agree to an attachment is very unlikely, I wouldn't allow it if the shoe was on other foot!

Lol or keep his wife entertained whilst he's at work ha ha ha. On a serious note I do need this question answering, if possible. :D

Hi all, quick question. my neighbour has a double extension with 1m deep foundations (trench fill). My planned garage extension will sit right up against the neighbours extension leaving a 4" gap BUT as i have just realised my footings will be right against the neighbours footings...

Mr G, Mr W The load is only a 3m x 2.2m high wall made of blocks so a 7x4 is plenty strong enough for that particular job. So, if the upstairs wall is sitting on the joists then needles will not be required. The only thing which will possibly happen is a few bricks coming loose and a...

Hi all. Having read loads of stuff via this website before it seems the best place to ask my question. I currently have a front and back room divided by a block built wall which is currently taking the load for the upstairs wall which divides two bedrooms and as i can see has the...

you lot are great, thanks a lot. Im liking the idea of trench blocks because im doing the brick work myself. Preparation is a massive part of doing my footings, slab etc. All i have done this weekend is read, read and read as well searching this forum for as much advice as possible. Its a...

Thanks for your reply. Im planning on insulating under the slab rather than on top. I was just trying to get my head round the weak concrete part. Spoke to a builder today and he looked at me as if to say 'what you on about'. He simply said 1m trench, 850mm concrete fill, brick up for dpc...

can the weak concrete infill (goes in the cavity) be level with the ground surface and the concrete slab??

can the weak concrete infill (goes in the cavity) go level with the ground level and the surface of the concrete slab??

this is without doubt the best website i have found http://www.myhouseextension.com/ click planning foundations for diagrams

I am currently using this diagram http://www.diydoctor.org.uk/projects/constructiongroundfloor.htm as an indication of whats required. Its the fact the concrete slab is placed so high above the ground level which is worrying.

Hi all. I am after as much info, diagrams and step by step guides as possible before i embark on my garage extension. I searched and searched but im yet to find one website which nails exactly what im after. I need help with footings and how to prep and pour the slab. I have a general...

Good point. It just seems strange that you can pour concrete on this insulation stuff and the floor feel solid under your feet. In my head i imagine the floor wobbling like jelly. Do you guys know of any helpful websites which outline step by step the process and materials required to do...

Hi and thanks for your replies guys. I wasn't planning on informing BCO because my neighbour has has a side extension done last summer so my plan was to dig down to there footings level and match what they have. Then photograph and video the entire project so when i do convert the garage into...

i shall beef that sucker up, lol The footings will be going directly on to clay. It will be a garage with no secondary floors so the only load on the foundations will be 1500 bricks and 200 blocks plus the pitched roof 300 tiles ish

Hi all. Im currently planning on putting a garage on the side of my house. My only problem is the size of footings for the gable end wall. Its 8.2m long by around 3m high (its gonna have a pitched roof). Im thinking of doing the concrete base etc as if i was having an extension built on the...

Q1: new felt was tucked under existing (2nd row) felt, so any water running down from the ridge would flow into the gutter. Q2: roof is standard semi detached with apex to the side of both houses. No velux or pipework. Q3: plumbing in loft is for the shower but no leaks on joints or...
