Abstract: A plate is used in conjunction with a drainage system. The plate provides an open path from a bleeder hole in a wall to a drainage trench in the floor. This facilitates water drainage from within the wall.

Abstract: An open vent plug minimizes blockage within a second hole drilled in a basement wall to minimize back pressure within the wall and insure ventilation through cells within the wall to drive water into a bleeder hole. The open vent port has a hole therethrough that forms an opening joining the cells and atmosphere. The vent port preferably has a screened opening at one or both ends to prevent debris from blocking the second hole, and sidewalls of the open vent port prevent the wall from crumbling into the hole and blocking airflow therethrough.
