Overview

Exterior Waterproofing In Toronto .

Exterior basement waterproofing is a reliable way to stop water from seeping into the basement of a building in Toronto. This process requires excavating around the foundation, repairing any cracks or defects, and then applying a waterproof membrane or coating on the outer side of the foundation walls. The objective of this method is to create a barrier that prevents water from infiltrating the basement, which helps to maintain a dry and livable space, preventing water damage and preserving the structural integrity of the building. Exterior basement waterproofing is an important element of building maintenance in Toronto, as it can prevent costly repairs.

Residential Exterior Waterproofing in Toronto .

Client Challenge: A homeowner in Toronto was experiencing ongoing issues with water intrusion through the foundation walls of their home. This was causing dampness and potential damage to the basement area, prompting them to seek a permanent waterproofing solution.

Our Solution: We recommended a thorough exterior waterproofing plan designed to prevent water from penetrating the home’s foundation, ensuring a dry and structurally sound basement.

Execution Steps:

  • Detailed Inspection: Our first step involved a comprehensive evaluation of the home’s exterior to identify the specific sources and paths of water intrusion. This assessment guided our approach to effectively address the root causes of moisture penetration.
  • Excavation: We excavated around the foundation to expose the exterior walls where water was seeping through. This allowed us to clean and prepare the surfaces for waterproofing treatment.
  • Application of Waterproof Membranes: High-quality waterproof membranes were applied directly to the exterior surfaces of the foundation walls. These membranes create a durable barrier against moisture.
  • Installation of Drainage Systems: Alongside the waterproof membranes, we installed an exterior drainage system designed to redirect ground water away from the foundation. This system includes perforated drain pipes wrapped in filter fabric, surrounded by gravel for enhanced drainage.
  • Backfill and Landscaping Restoration: After the waterproofing and drainage systems were in place, we backfilled the excavated areas with soil and restored the disrupted landscaping to its original condition, with improvements to grading to further direct water away from the home.
  • Protective Coatings and Insulation: As an additional protective measure, we applied a layer of protective coating over the waterproof membrane to shield it from physical damage during backfilling and provide insulation against cold.

Challenges and Resolutions:

One challenge was dealing with unexpected underground utilities found during excavation. We carefully navigated around these utilities, adjusting our excavation and drainage plans to avoid disturbing them while still providing complete waterproofing coverage.

Results:

The exterior waterproofing was successfully completed, leading to the elimination of water ingress into the home’s foundation and basement. The homeowner was extremely satisfied with the end result, particularly appreciating the thoroughness of the initial assessment and our careful handling of the landscape and utilities.
