EXTERIOR BASEMENT WATERPROOFING
Waterproofing the basement from the outside is the most recommended waterproofing method in Toronto. The Exterior Basement Waterproofing protects the basement interior and foundation walls from water damage.
The Exterior Waterproofing System is a combination of foundation protection materials (Foundation Coating, Parging, Membrane) and water management systems (Weeping Tile, Window Well, Sump-Pump, Gravel).
Exterior Basement Waterproofing can be a costly and time-consuming venture, though the overall value and protection waterproofing offers your home makes it a valuable investment. Exterior waterproofing should only be done by professionals, as the process is often more complicated and precise than many homeowners suspect. Exterior waterproofing encompasses excavating the perimeter of the home’s foundation. Once the perimeter has been excavated, old drainage systems are replaced and the foundation examined for signs of cracking and water damage. A rubber membrane is then applied to the foundation along with a second membrane for drainage. These membranes are then covered with loose gravel in order to facilitate drainage. The excavated area is then filled and compressed to the same level as the surrounding soil.
All construction projects begin from the foundation up. After the foundation is laid and set, contractors begin to build the structure of the edifice over it. On homes, the sill is the line where the foundation and structure meet. The sill is one problem area where water has the potential to enter if not sealed correctly or should the seal deteriorate over time.
Similar to the sill, points where newer additions to your home, extensions, and renovations meet, are highly susceptible to leaks. However, water damage stemming from extension points is generally minor and easy to remedy using proper sealants.
Sitting just beneath ground level, window wells are vulnerable to water damage; particularly those with poor drainage systems. A buildup of water inside a window well can lead to seepage inside and around the window. This can be avoided by regularly replacing damaged window wells and ensuring the existing drainage systems remain clear of debris.
Brick foundations often complicate the flow of water. Encompassing numerous air pockets and joints in their mortar, brick foundations may become waterlogged. As a result, waterproofing brick foundations can be done either by internal or external waterproofing, the overlap of which is recommended in order to reinforce any weak points. Because bricks can become easily saturated with water, brick walls may be drilled through in order to expel excess moisture.

EXTERIOR WATERPROOFING FAQs
How much does exterior waterproofing cost?
The mid-price of exterior waterproofing is $25 per square foot of foundation wall area.
The calculated area is the surface located underground. So, if you have an 8-foot tall basement inside, but outside there are only 6 feet of the foundation under the ground, the area of waterproofing will be 6 square feet per linear foot of the wall.
How do you do exterior waterproofing?
Excavate the exterior part of the foundation. Fix or restore the wall. Seal the wall with a special waterproofing coating. Install the drainage membrane on the wall. Install Weeping Tile drainage system. Apply the gravel bedding with a filter. Backfill the excavated area and compact the soil.
How long does exterior waterproofing last?
High-quality exterior waterproofing lasts 50+ years. The system should be professionally designed and installed, using high-quality materials.
