If you do install drain tile near a buildings foundation, I suggest using the cloth sleeved type. It doesn't clog up near as quickly as the regular corrugated tile. One other product that may really work well for your wall bases is called Perma-Drain. If you are not familiar with it; it is basically a hollow, plastic 2" by 4"(comes in different sizes) that has small slots in it. It's normally used to form building footings. It's real fast and easy to install it level, and it's a superior drainage system. It can also be set to allow flowage between in and outside runs of tile.
Neat stuff and a huge time saver, but not cheap! Tim
