OK As purchased 3-2012: Built in 1940, 25' x 25', block foundation, sitting on a poured slab. At some point someone added drain tile by cutting a trench through the floor about 4" from the wall. This goes across the entire East and South walls. The North wall has it from the East, one half way to the West. The West wall only has about 4', from the South to the North. It is a 3" tile, with the top, at the same level as the slab. They drilled holes at the bottom of the lowest course of blocks. To "bury" it they laid bricks on their sides, about 12" from the wall, filled the area with pea gravel, at poured concrete over the gravel, out to the bricks. We had a little water issue in the Spring of 2012. We attributed it to the downspouts, no window well covers and a unsealed gap between the driveway and the foundation. We moved the downspout 15' from the house and sealed the driveway seam. BONE dry until January. Then we had water from a new area. We had plumbers come in and remove the old tile and install new. This is under the floor which means they took out the bricks, trenched, set the new tile completely around the inside of the foundation, and poured the floor flush. they also plugged the holes that were drilled for the old tile. Now I have water everywhere. The walls have places 2' up that have water squirting in a stream 8" from the wall. This is 99% due to plugging the old drian holes so the walls are filling up. Why the tile isn't taking the water, I don't know, but it doesn't start to flow from the tile to the sump until 30 min after the walls start leaking. I'm considering a baseboard system as a supplement to the new tile. That would reopen the old drain holes and channel it to the sump pump. Any ideas, or experience welcome!
