Hi Pompey, I used the same principle for my man-cave. Only much smaller all round. Basically a slab with double thickness where the walls went and some steel mesh to stop it cracking. Best of luck with your build and thanks for the comment.
I am no expert by any means, but looking at the gauge of the steelwork and amount of stone, it feels like you are preparing the foundation for some some really heavy loads. Hand on heart was it necessary? Was there any bearing capacity calculations for your building before deciding all the parameters for your foundation? Thank you in advance. P.S. I'm in the process of building a garden gym and will have to go through similar process.
Hiya, completely missed this comment, apologies. We did fight the structural engineer stating we 'weren't' building a multi-story carpark but the ground was so bad he wouldn't accept any less. I assume your gym is all complete? 100mm slab with mesh through the middle would be plenty?
Hi Leon, No need for starter bars. They didn’t want any of the steel exposed to air. This will be a timber framed house so only one block high to go on the raft before house goes on. It will have a brick outer skin but still no need for starter bars. Cheers Haydyn
@@handyhayd thank you very much for the reply truly appreciate it... can I throw one your way again for, so since for timber no starter bars are necessary is it the same for cement fibre based boards for a three story building? Working on a project and I dont see any starter bars there even though they are on the drawings is it the same as timber or no?
@@understandingaddicts You need to check with your Structual engineer as if they are needed the chances are the bars will go through the damp course and will need treating with a bitumen paint. Often more hassle than there worth!
Hello Andika, Soils samples were taken every metre over the whole site. The outcome was that the ground was not very stable (just pure soft sand in places) so that’s the reason for a raft foundation. It is calculated the if a 1/4 of the earth underneath washed away...the raft will still hold the house up. It transfers the weight over the whole site rather than concentrated areas. Was that what you are asking Andika?
We could have put a plastic membrane but we used concrete 'blinding' instead. The engineer gave us the option and our thought process was to let the water drain away rather than sitting in a swimming pool as any water will have nowhere to go. I know in some climates you have to use a membrane because of termites. This is not relevant in the UK. Your thoughts?
F me!
I found you while assessing foundation options for my 30m^2 man cave.
Not all applicable to me, but I did learn a lot.
Thank you for posting :)

Thanks for your upload, am just about to do a self build, can I ask what company you used to get the steel cages constructed. Thanks.
Hiya, sorry for late reply. Just use the nearest one to you to keep delivery easy. Have you started?

There are no starter bars for the walls is that normal or does the shuttering not necessitate the use of starter bars

How can I contact you? thanks.
sorry sir can i ask about your first preparation and details about this project , sorry if my english is bad

Why put mains water pipe in sewerage pipe should be in a black protected pipe .
Not sure what you mean by black protested pipe?
Why dont u isolate foundation ? Water and humadity damage the steel in time...steel will decay..

@@handyhayd should use membrane for protect foundation.
The beam pictured at 13-48 is off square not much given the width of the beam but it sure is off
Nit picking there
