ABSTRACT:
A drainage system comprising an earthen trench adjacent to a foundation wall formed from hollow blocks or bricks, the inner surface of the lowermost course of which is provided with holes communicating with the interior of the blocks, allowing water passing down the interior of the wall to have access to the trench. The drainage trench is provided with a shaped profile, supported from the inner side of the wall, which serves as a lining for the top and one side of the trench, the lower portion of the wall, or a footer wall, comprising the other side. The bottom of the trench is lined with a water-permeable fibrous mat.
