Exterior Waterproofing In Mississauga .

Exterior basement waterproofing is a technique used to prevent water from entering the basement of a building by applying waterproofing materials on the outside of the foundation walls. In Mississauga, this process involves excavating around the foundation to expose the walls, repairing any cracks or defects, and then applying a waterproof membrane or coating. The main purpose of this method is to establish a barrier that prevents water from infiltrating the basement, thereby safeguarding it against water damage and ensuring a dry and healthy living space. Performing exterior basement waterproofing in Mississauga is critical in maintaining the structural integrity of buildings and avoiding expensive repairs in the future.

Residential Exterior Waterproofing in Mississauga .

Client Challenge: A homeowner in Mississauga was dealing with persistent moisture problems in their basement, particularly during the rainy seasons, which led to concerns about mold growth and structural damage. Seeking an effective long-term solution, they contacted our team for professional help.

Our Solution: We proposed a comprehensive exterior waterproofing strategy tailored to address the specific moisture issues at the property, ensuring that the basement would remain dry and protected from water damage.

Execution Steps:

  • Initial Assessment: A thorough inspection of the home’s exterior was conducted to identify the sources of water intrusion and evaluate the condition of the existing drainage systems and foundation.
  • Excavation and Surface Preparation: We excavated around the foundation perimeter to expose the affected walls. The surfaces were then cleaned and prepared for waterproofing treatment.
  • Waterproof Membrane Installation: A durable waterproof membrane was applied to the exterior foundation walls. This barrier is designed to prevent any external water from entering the basement.
  • Drainage System Enhancement: We upgraded the existing drainage system by installing new weeping tiles and proper grading to ensure efficient water diversion away from the foundation. This system helps to manage surface and subsurface water flow.
  • Backfilling and Landscape Restoration: After the waterproofing and drainage enhancements were completed, the excavated areas were backfilled. We carefully restored the landscaping to its original state, ensuring proper grading to facilitate water runoff.
  • Final Waterproof Coatings and Insulation: Additional waterproof coatings were applied over the membrane for extra protection against mechanical damage and thermal insulation was added to improve energy efficiency.

Challenges and Resolutions:

During the excavation, we discovered areas of the foundation that had previously undocumented damage and deterioration. To address this, we performed necessary structural repairs before proceeding with the waterproofing measures, ensuring the foundation’s integrity and stability.


The exterior waterproofing project was successfully completed, resolving the basement’s moisture issues and significantly enhancing the overall health of the home. The homeowner was impressed with the meticulous approach to ensuring every detail was addressed, from initial assessment through to the restoration of their yard.
