There are many people choosing to build with I.C.F. (insulated concrete foundation) systems these days. The product and method of construction might seem new to our Province, however, I prepared drawings for my first ICF house near 15 years ago. The client who built that first ICF called awhile ago saying he was going to build another - that's a good testament to quality of technology.
There are many different manufacturers of this product - here's one particular product available locally. http://www.logixicf.com/index.php?n=builder&mode=product
