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.
Claims19
A method for waterproofing a below- or at-grade room comprising installing an open vent port for insertion comprising:
- an elongated body having an open channel extending longitudinally therethrough that joins two open ends;
- a screen spanning the open channel;
- a convex annular first lip extending from the end with the screen towards the end without the screen;
- and
- a convex annular second lip extending from the body located between the two open ends, the second lip having a first end with a first diameter and a second end with a second diameter that is less than the first diameter, the first end being arranged closer to the convex first lip than the second end.
A method of waterproofing a below- or at-grade room having a floor and walls having an open cell therein, the method comprising the following steps:
- forming a trench through the floor adjacent to the wall;
- drilling at least one bleeder hole into the wall into the open cell;
- drilling at least one second hole into the wall into the open cell;
- installing an open vent port comprising
- an elongated body having an open channel extending longitudinally therethrough that joins two open ends;
- a screen spanning the open channel;
- a convex annular first lip extending from the end with the screen towards the end without the screen;
- and
- a convex annular second lip extending from the body located between the two open ends, the second lip having a first end with a first diameter and a second end with a second diameter that is less than the first diameter, the first end being arranged closer to the convex first lip than the second end into the wall;
- wherein the second hole relieves back pressure through the bleeder hole when water flows from the open cell through the bleeder hole;
- wherein the second hole provides ventilation to the open cell.
