Verticle drain tiles can be seen in the picture to the left. They are the vertical black pipes.
Two layers of 6 mil plastic are placed over the tar.
The 3 inch perforated pipe is placed vertically along the walls and at all window wells.
A 3 inch draintile is also placed along the footing and covered with gravel.
This pipe drains exterior water into the sump pit, floor drain or natural drain. |
