1. Using a jack-hammer, the basement floor is opened adjacent to the wall. A trench is excavated. The width is determined by the width of the foundation footing. The depth is limited since it may not be lower than the bottom of the footing.

2. Holes are drilled in the blocks below floor level to release water trapped in the hollow blocks. (This step does not apply to poured concrete foundations.)

3. Fully slotted polyethylene or PVC pipe is laid in place and covered with gravel.

4. The floor is re-cemented to its original level with a one inch expansion allowance left between the wall and the floor.

5. To discharge the water, a submersible sump pump is installed in a covered polyethylene container.

6. From the submersible pump, a discharge line is run up the wall. Through a drilled hold in the wall, the discharge line is extended. 7. Bentonite may be dry-poured through holds drilled approximately three feet apart on exposed exterior portions of the sub-soil masonry. When Bentonite mixes
