how to expand concrete?
« on: July 30, 2012, 07:19:14 AM »
i'm thinking of adding 150mm wool around the house(to get a 0,21 U number) and later lay bricks around that to get a durable finish, but i probably need to expand the foundation a bit to hold all that weight.... i haven't calculated the exact overlapping thickness yet, but is it even possible to expand the foundation with new concrete and rebars?
