ok thanks for that ivixor.. am i ok with 150mm hardcore and 100mm concrete, should i put dpm in? if I decide to build a brick garage, is it ok to build on top of a self leveling compound? Also, the concrete slab to the right in the pics.. will this need to be broken up or can i concrete over...

Thanks for that... any idea if I am able to get a reasonable size log burner in that space. without opening it up?

After closer inspection... I am more concerned about opening the space behind the front skin of the fireplace because of the bricks tapering up which i now believe is called cobels.. I guess these are load bearing.. and how do i get around it.. any advice would be very much appreciated (see...

Hi all, I want to extend a garage and thought at first it would be a simple task of removing one wall getting some more concrete panels to extend the back wall, concrete the base, and put the wall back, however ive realized the concrete floor that the garage currently sits on is out of level by...

I just chucked it in so to speak... I do remember it had 3 wires that were visible at each end. (i think you can just see them in pic) there was an arch in the brickwork originally but it was knackered... The lintel is placed pretty much where the original arch was and i obviously I did not have...

Ive attached a couple of picks.. first one is one that I did around 6 months ago.. the second is the one that I want to do now. the span will be around the same.. I never realized I was supposed to put the lintel long ways up.. do you think that it will be ok? and do you think its ok to do the...

Hi all I want to place a 210 x 100 x 1800 concrete lintel above fire place, only 100mm will actually sit inside the wall the the rest will be on the outside creating a mantel piece My query is should this lintel only be installed with the high side (210mm) sitting vertically? or am I wrong...

Hi all, I am trying to understand what is required in the structural aspects of building dormer extensions - what materials, easiest and most cost effective way... if poss..! I have made a building control application but still havent had first visit from them. I have attached here 2 photos and...

I will ask the building inspector if its ok if I completely fill in the voids between joists with insulation then no airflow required... I would imagine though that its pretty difficult to completely fill all space 100% no?

Ok, I understand.. however, if i do it the cold roof method.. he wants me to still increase the roof height by putting in cross members then vent it from the front of extension to the back wall.. then construct up the back wall a space and have it vented there.. I think the warm roof method is...

Trouble is Im sure he would make me pay for it with other things he could insist i do..

Ive had building inspector today... and thats what he said I should do.. Trouble is it will raise my side height to the neighbors extension by 100mm.. How do I get a proper finish/seal on their side?

Its got 25mm upright insulation on all walls, I didnt put expansion gaps.. just made a couple of cuts around 1/3 through concrete so when it cracks hopefully it will crack there... the dpm is only to hold the concrete.. it needs to be taped up properly where necessary... walls are injected with...

Hi all, Im going to GRP a 12sqm flat roof on extension which abuts neighbors extension on one side I am doing work through building regs... and they want it insulated with 100mm king span between joists then 25mm under that. I am guessing that they will accept 75mm between joists but this still...

Well finally got my floor down see pics... very happy with result.. :) there is 150mm of type 1 hardcore, around 20mm of sharp sand, dpm, 150mm of insulation, dpm, self leveling concrete.. which is absolutely bang on level.. I guess you was having damp rising because there was not dpm

He told me he should have done it with water but it would have been difficult to get the water out

Sorry for confusion.. second pic doesnt help.. The 2 45s are joined opposite way to each other to create a type of S shape which brings it down to an attachment creating a slight offset to vertical... I used to connect a none underground fitting it wont be in contact with cement.. and my main...

Hi all, Broken soil pipe.. (pic attached) ok.. I have leveled the top of it and put 2 x 45 degrees to create something giving a correct height closer to finished floor level (pic attached) What Ive done though without realizing is lessen the flow direction Does anyone think that this will cause...

Its all pipework.. supply, heating, hot and cold... I know now I should have had it done differently... to late though to start ripping it up.. guess its a matter of live and learn.. cant rely on tradesmen to give you the best advice.. its simply whats easiest/best for them.. Unless someone can...

Hi all, Im in the process of renovating an old terraced house which had the original old floating wooden floor. I have removed it and got hardcore down ready for sand and insulation then final concrete. I have had gas fitter install all pipework on the top of the hardcore.. Is this ok.. or...
