Odd waterproofing method?
Has anyone run into this type of thing in an older home? We live in a home built in 1928. Five years ago, the previous owners had 25 feet across the front of the house and 15 feet up the adjacent side 'waterproofed'. Meaning the exterior perimeter was dug down to the footer, new mesh covered perimeter tiles installed, a material applied to the basement wall exterior, pea gravel and whatever poured back into the trench. (We were given a 'transferrable' 10 year warranty...ha ha). Anyway, we noticed during very wet times there can be some dampness on the basement along that wall. Of course the waterproofer is fairly uncooperative, so we've started our own investigating. Along that wall is panelling and some builtin cabinetry...we pulled a small part of the cabinetry from the wall and noticed that there is a narrow interior trench filled with gravel along that wall...I think that the water may be coming up through that trench. It's probably about8-10 inches wide and is running along the inside of the walls that were 'waterproofed' from the outside. I've never seen anything like it, and the 'waterproofer' never investigated behind the panelling to see what might be happening on the inside. He really doesn't know what it is, it must be some type of old drainage system that isn't very effective. Any ideas on how to eliminate it or what to do with it? I think it needs to be sealed off, but I'm not really knowing who would do such a thing. One of those B-Dri basement type companies? ANY comments would be appreciated.
