Insulating the slab couldn’t be easier!

My new workshop will be very energy efficient and we achieve that with a lot of Insulation. The great thing about the Atlas System is that it is very easy to install and it also eliminates the need for further concrete forms. The foam itself is the form that holds the concrete in. We added 12cm underneath the slab and 20cm along the perimeter. #concrete #construction #making #diy #homebuilding #building #architecture #energy #heatloss #insulation #foundation #bauherr #housebuilding #groundwork

Don't really understand if it has overlap layer and if the gaps should be filled with some compound for waterproofing

This series is very interesting for someone like me as we make house completely different in india (state-Bihar) as we do not even get snow in winter and lowest temp was in 2013 -1°C

I looked at the stuff that allows you to install pex tubing along with the insulation and found that for about my area its nearly 20k yet when priced out the cheaper 2 inch foam plus the foam for the sidewalk around the building and the foam for the trench just at the edge of the sidewalk its 4500 dollars. A pallet of concrete bricks, rebar and zip ties is more than enough to hold down the pex pipes. The pallet of bricks instead of rebar chairs. Though the rebar chairs mean that you do not have to tire the rebar. 3000 chairs required for every single cross point is 2k additional dollars. I am still thinking a tile cutter and a pallet of bricks plus my free labor is cheaper.
Years ago I helped layed concrete for a summer and the boss would skimp on the chairs so bad that if you stepped on the rebar it would sag the whole thing to which they would grab it and pull it up. Its very clear it was some shoddy work.
With the pex I do not want to risk the chance of the pex being pushed down or pulled up where its not suppose to be.

Have there been any long-term studies of this foam? Seems like we jump into this stuff and no one knows in ten years if it will break down and then your entire slab is compromised.
