Re: Basements in the Wilds of Alberta?

The job I referred to previously had to go down 15'. The contractor had to hoe-ram it. Water was pouring into it like Niagara Falls as it was below the Niagara escarpment. The contractor had to excavate a deeper hole beside it to drain the water away so he could work in the hole. Two pumps were necessary.

Yeah, digging the hole isn't so much the issue as that we typically use
sheet pile to form this kind of thing - it's a pipe valve vault - a dry
