Waterproofing your basement is like giving your home a raincoat, but the big question is: should you tackle waterproofing basement walls from outside, or waterproofing basement walls from inside? At Rock Bottom Underpinning, we’ve been helping homeowners across Toronto and the GTA solve their basement woes for over 15 years.

Basement Waterproofing From Inside

Interior waterproofing does not stop water from reaching your foundation, but it keeps it from sneaking into your living space. This method is great for tackling minor issues like damp spots or small leaks without digging up your yard.

• Sealing Walls and Floors: Products like waterproof paint, concrete sealers, or coatings are applied to the walls and floors inside your basement. These create a barrier that blocks moisture from coming through tiny cracks or porous surfaces.
• Adding Drains and Sump Pumps: Drains and sump pumps work like a dream team to collect and remove water before it becomes a problem.

Since interior waterproofing happens inside your home, there’s no need for heavy machinery or major excavation. It’s fast, less expensive, and perfect for homeowners who need a hassle-free solution.

Basement Waterproofing From Outside

While interior waterproofing focuses on damage control, exterior waterproofing takes the fight to the source. This method keeps water away from your foundation entirely, offering a more permanent solution.

• Sealing the Foundation from the Outside: This involves digging around your foundation to apply a waterproof membrane and seal cracks. It’s a bigger job but delivers unmatched peace of mind.
• Installing Weeping Tiles: A weeping tile system is installed to redirect water away from your foundation, keeping it from pooling around your home.

While exterior waterproofing takes more time and effort, it’s worth it for its durability and effectiveness. If you’re planning a major renovation or building a new home, this is the way to go for all-around protection.
