Here are few illustrations on how water can damage your basement and home foundation:
Exterior Waterproofing Process
1. Exterior waterproofing requires excavation around the perimeter of the building.
Most excavations range from 4 to 8 feet deep and approximately 2 ½ feet wide. The dimensions of the excavation are dependent on the elevation of your property.
2. Installation of Speed Shoring.
This is done to ensure the safety of workers while preventing soil re-filling the area of excavation.
3. Old Weeping Tiles are Removed.
Excavation is done util the footing is reached and the old weeping tile can be taken out. A new 4-inch weeping tile with a filter cloth is then installed.
4. Cleaning and Inspection of the Foundation Walls.
Foundation walls are then cleaned and inspected for any voids or structural cracks. The defective areas are chiseled out and repaired with non-shrink specialized cement which expands when applied to the crevices.
Application of Trowel-On Rubber Membrane
5. Application of Trowel-On Rubber Membrane.
This is a central component to exterior waterproofing your foundation. Its designed to elongate and expand in case of further foundation movement and settlement.
6. Installation of mesh on top of membrane and final layer of rubber waterproofing.
This is used to reinforce the first layer of the rubber membrane and acts as a secondary rubber layer.

7. Soil side drainage sheet is fastened to the top of termination bar.
Commercial grade drainage acts as a protection board and drainage membrane (much better than residential grade dimple board).
8. Installing Window Wells.
If your home has any windows below grade and you require a window well installed. A 4-inch weeping tile is installed vertically down from the inside of the window well to the footings. To prevent clogging, makes sure your weeping tile and pipe do not touch.
9. A layer of 3/4 inch clear gravel is placed over the weeping tile.
Used to maximize the level of drainage. The layer of gravel is mixed with soil to prevent too much water absorption through the weeping tile, which could lead to slowed drainage or clogging.

10. Area is refilled with native soil and compacted to the original level.
Once the soil has been restored to its original places, you have fully waterproofed your foundation and will have no further issues with water penetrating your basement exterior or interior.
