Understanding Exterior Waterproofing
Diving into the domain of exterior waterproofing, it’s crucial to understand what it entails. Think of exterior waterproofing as your home’s first line of defense against water intrusion. It’s like a shield that protects your home by preventing water from permeating through its exterior surfaces.
Exterior waterproofing involves applying a waterproof membrane or coating to the outside of your home’s foundation. This membrane, typically made of asphalt-based or polymer-based products, creates a physical barrier that blocks water from seeping into your basement or crawl space.
The process requires excavation around your home to access the foundation walls, which is labor-intensive and can be disruptive to your landscape.
In addition to waterproofing membranes, weeping tiles or French drains are often installed at the base of the foundation. These systems collect water that accumulates around the foundation and divert it away from your home, further enhancing the effectiveness of exterior waterproofing.
Exterior waterproofing also includes the process of damp-proofing, which involves applying a thin coating of water-resistant material to the surface of the foundation.
However, unlike waterproofing, damp-proofing doesn’t provide a full-proof barrier against water penetration.
