I took this funny photo today of one of my concrete guys from Bear Creek Construction. I figured I’d describe the “green” technique/material they’re using which I use on almost all my custom homes.
Polystyrene foundation blocks, also called ICF block (Insulated Concrete Forms) are really energy efficient and add lots of insulation value to a home. It’s more expensive than normal concrete foundation walls but is quicker. The foam blocks are 24 inches long, 16 inches tall and hook together like Legos. When used for an entire house, foundation and vertical exterior walls it really gives a solid, well insulated house.
