Wouldn't you know the day after we finished our third concrete pour of three for our 44x56 barn restoration project in central Maine, I would find this website saying tekfoil under the slab on grade is NOT the way to go. After much research we decided to use tekfoil(foil,bubble,bubble,white poly) under our six inch slab. We did haul in about 700 yards of good gravel to sit the foundation on. We put radiant floor tubing in two zones, one of which(12x56) is going to be an apartment. The rest of the barn we put the tubing in just for the future so it would be there. We put 1" styro all around the outside edge, the thickness of the exposed slab. We hope to heat it with four 4x10 solar panels and a wood boiler. How can we make the best of our situation now? |
