ADVANCED CONSTRUCTION in Sudbury, Ontario is responsible for the workmanship you see in these photos. My garage floor has dropped by at least three inches. There are huge cracks in both garage and house foundations... where you can see through to outside. The garage floor has HUGE cracks. And some of the blocks on the garage foundation have actually shifted off somewhat. And when asked to fix, they parged a bit... never came back to fix anything. When contacted again, they ignore me.
