Waterproofing your home’s basement and foundation walls is a crucial step to protecting your building and contents from the damaging effects of water ingress. Concrete is a popular building material used to construct basements and foundation walls. Although concrete is durable, it is not waterproof on its own. Water can seep through small cracks and gaps, leading to dampness, mold growth, and structural damage. Waterproofing your basement and foundation walls involves applying a protective layer to keep water out. In this article, we will learn how to properly waterproof basements and foundation walls in concrete structures.
Why Waterproofing is Important
Water damage to your building can lead to a host of problems from mildew to foundation cracks. Here are some reasons why waterproofing is essential:
-
Prevents water damage: Water damage can cause structural problems like foundation cracks, mildew, and mold. Waterproofing solutions help prevent water from destroying your home.
-
Keeps your home healthy: Water damage is a breeding ground for mold and bacteria, which can cause allergies, infections, and respiratory problems. Waterproofing keeps your home safe and healthy.
-
Increases home value: Waterproofing your home can increase its resale value.
Types of Basement Waterproofing
There are two types of basement waterproofing: Interior and exterior waterproofing.
Interior Waterproofing
Interior waterproofing solutions involve treating the walls and floor of your basement from the inside. Here are some common interior waterproofing methods:
-
Injection Waterproofing: Injection waterproofing seals small cracks and gaps by injecting a water-resistant resin into the holes.
-
Interior Drainage System: This waterproofing system involves installing a drainage system inside your basement walls. Water flows to a sump pump, which pumps the water away from your home.
-
Sealants: Sealants are applied to your basement walls and floor to create a waterproof layer. This method is easy to apply, but it is not ideal for extensive water damage.
Exterior Waterproofing
Exterior waterproofing solutions are applied to the outer walls and foundation of your home. Here are the two primary exterior waterproofing methods:
-
Excavation Waterproofing: This method involves excavating the soil around your home to apply a waterproof membrane or coating to the foundation walls. It is a costly and time-consuming process.
-
Drainage System: A drainage system is installed around your home to channel water away from your foundation walls and home.
Waterproofing Foundation Walls
The foundation walls are the first line of defense against water damage. Here are three ways to waterproof foundation walls:
Installing a Water-resistant Coating
Water-resistant coatings are applied to the exterior walls of your foundation. This coating is relatively inexpensive, making it perfect for small water issues.
Drainage Boards
Drainage boards are applied to the exterior walls of your foundation. The boards provide a channel for water to flow away from your foundation walls.
Installing a Waterproof Membrane
Waterproofing membranes are installed on the outer walls of your foundation. These membranes provide a long-lasting and reliable waterproofing solution.
