Waterproofing contractor has other ideas
My plans called for placing the foundation drain pipe next to the footer. This is a non-standard practice in my area and required digging and pouring a thicker 12 inch footer instead of the typical 8 inch footer used in these parts.
Now, the waterproofing contractor is refusing to place the drain line next to the footer. Several years ago he switched to placing the drain (a rectangular pipe) on top of the footer and thinks this is the better method.
I’m annoyed and confused since I was advised by another credible expert that placing the pipe on top of the footer would greatly increase my chances of springing a leak (thus, the 12 inch footer). My builder is inclined to go with the “on-footer” method since he’s had good experience with that approach, but he will do whatever I want.
So what is industry best practice. Putting the pipe next to the footer makes intuitive sense to me, but I know that what’s intuitive isn’t always correct. I just don’t want a basement that leaks.
