Basement Waterproofing FAQs

The durability of a waterproofing solution is influenced by several factors, including the quality of materials utilized, the extent of water issues addressed, and the regularity of maintenance. High-quality materials and expert installation can ensure that a professional waterproofing solution lasts for an extended period, often ranging from several years to multiple decades. However, it’s essential to conduct periodic inspections and maintenance to ensure the continued effectiveness of the waterproofing system over time. Regular upkeep can identify and address any emerging issues promptly, thereby extending the lifespan of the waterproofing solution and preserving the integrity of your basement.

The best basement waterproofing method depends on factors such as the type of foundation, severity of water issues, and budget. Common effective methods include exterior waterproofing, interior drainage systems, and waterproof coatings or sealants. Exterior waterproofing involves creating a barrier outside the foundation walls to prevent water intrusion. Interior drainage systems, like sump pumps and French drains, manage water inside the basement. Waterproof coatings or sealants add an extra layer of protection to basement walls and floors. Consulting with a professional can help determine the most suitable method for your specific needs.

Waterproofing a basement from the inside involves several steps. First, identify and repair any existing leaks or cracks in the walls or floor. Next, install an interior drainage system such as a sump pump or French drain to manage water buildup. Apply a waterproofing membrane or sealant to basement walls and floors to create a barrier against moisture intrusion. Proper insulation and ventilation also help prevent condensation and moisture buildup inside the basement.

The cost of waterproofing a basement in the Greater Toronto Area varies depending on factors such as the size of the basement, the extent of water issues, and the chosen waterproofing method. DGI charges $6 to $8 per sq. ft. depending on materials and company.
