Finally broke ground today!
My build will be loosely based on Kiko Denzers 22.5" oven instructions, augmented with many tips from this forum.
I staked the ground in the middle of where I want the oven, and with a measuring tape channeled out out a 48" diameter through the turf.
I then dug down about 2 feet into the topsoil till I hit clay so kept going till I thought I had excavated enough for my build, I now have 1 standard black bin full and a half full wheelie bin of clay.
Will hopefully get some aggregate tomorrow for drainage.
Then I'll be out and about looking to scavenge urbanite for the walls!
Will try and figure out how to post pics of progress.

I have now backfilled he hole to a level I thought suitable with topsoil tamped down, and then set down a layer of old bricks lying about between mine and my neighbours garden (thanks skipper d) and on top of that spread 5 bags of B&Q,s cheapest drainage stones. Attachments:

I have also got my hands on 11 bags of sharp sand which I thinks about 200 kg, so my next step is to scavenge the urbanite required to build up the walls. Just need the weather to improve.
Spoke to someone at the Glasgow Brickyard Co today about bricks for my hearth and they offered me clay commons which I could have for 12 pence each plus VAT.
Does anyone know if these would be suitable?

Nice work on your base. One point.....a lot of people have come unstuck building a "full" base without a damp proof course. Just remember you need to stop any rising damp getting to the underside of your slab/hearth. DPC, damp proof coarse and DPM damp proof membrane are used. If you are thinking of a full stone base or similar you can always put some waterproofer in the mix in the lower part of your wall.
Clay bricks will work but they are the least affective for heat retention and at 12p each they may not be the best. If you can't get fire-bricks or storage heater fire bricks, then "staffordshire blues" (the full SB's) have been spoken about lately as being a good alternative to fire-bricks. They are about 60 or 80p each and are known as "Blues" and most brickyards stock them. Maybe a second opinion from the brickyard may be worthwhile.

Hi Terry,
My intentions was to dry wall it and rely on the weight to hold it in place, i was going to place a DPC between the 1st and 2nd layers. and whist the individual prices for bricks at Vitcas are within range once I add on shipping costs it multiplies it by 4. I can not find anywhere in the Glasgow area that sells firebricks, do you know of any?

I think i'd pass on the commons too. I always remember them as being a bit bottom of the pile regarding quality. Alright for building a garage or shed base! Like Terry says...Class A Engineering Brick, solid, heavy, and blue or black in colour would be your next best bet, if you can't find some old victorian solid clay bricks. Again heavy, maybe slightly larger than normal bricks and quite often not frogged, or with a small one. Have fun scavenging your stuff, i loved that bit and got quite an eye for spotting parts, and brave to just knock on doors "asking".  |

Terry,
Many thanks I will be giving John Cameron's a phone in the morning, they are only 4 miles from me, I hope they still stock the firebricks. Even if I need to drive out to Falkirk it would work out cheaper than shipping!
bookemdanno thanks for the advice, as you can see I may have a few local options, as they say 'if it sounds to good to be true' it usually is!

Terry,
Also meant ask about the thermolite or insulation blocks. Is this just the standard 'breeze' blocks used in place of standard building bricks, or are they different I heard someone mention that they are lighter?

Terry, Also meant ask about the thermolite or insulation blocks. Is this just the standard 'breeze' blocks used in place of standard building bricks, or are they different I heard someone mention that they are lighter? These lightweight blocks are used on the internal walls of all new house builds. They come in various different makes but are all the same product. B & Q blocks are good as they are usually stored in a dry warehouse making them very light and easy to cut with a normal hand-saw.... www.diy.com/nav/build/building-materials/bricks-blocks/Celcon-Standard-Aerated-Concrete-Block-3-6N-Grey-7-3kg-9273673 Terry |
