What Is Exterior Waterproofing?
You may notice problems like standing water, foundation cracks, and musty smells as spring approaches and rain becomes more frequent. These issues often stem from poor drainage around the foundation. Exterior waterproofing is one effective way to prevent moisture intrusion, stopping water before it ever gets inside.
These solutions are especially valuable during the rainy season, when excess groundwater and heavy downpours can overwhelm your property’s defenses. But while exterior waterproofing is a critical part of your moisture protection strategy, it’s not the only one – your basement and crawl space still need attention.
Here’s what you should know about exterior waterproofing, why it matters, and how to protect your whole home from water damage.
What Does Exterior Waterproofing Involve?
Exterior waterproofing is the process of sealing and protecting the outside of your home’s foundation to keep water from entering. Unlike interior systems that deal with water after it gets in, exterior waterproofing is a proactive barrier that prevents water from reaching your basement or crawl space walls in the first place.
A typical exterior waterproofing system may include:
- Excavating around the foundation to expose the walls
- Applying a waterproof membrane or coating to seal the foundation
- Extending your downspouts or installing yard drainage solutions to carry surface water away from your home
Why Homeowners Should Consider Exterior Waterproofing
Spring rainstorms can quickly overwhelm your property’s natural drainage, especially if your home is near a water source or has high clay content in the soil. Exterior waterproofing helps:
- Prevent water infiltration through cracks or porous concrete
- Protect structural integrity by reducing hydrostatic pressure on your foundation walls
- Reduce the risk of mold and mildew in your basement or crawl space
- Improve indoor air quality by keeping moisture out of your lower levels
- Increase your home’s value by preserving your foundation and creating a healthier living space
