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
Signs You May Need Exterior Waterproofing
Walk around your home and inspect carefully for these red flags.
- Cracks in the foundation or basement walls
- Water stains or efflorescence on interior walls
- Pooling water around the foundation after rain
- Persistent dampness in your basement or crawl space
- Peeling paint or warped wood near the lower levels of your home
- Unpleasant odors or signs of mold
- Basement flooding or standing water
These symptoms suggest water is finding its way in due to inadequate protection on your home’s exterior.
Don’t Overlook Your Basement and Crawl Space
Even with exterior waterproofing in place, your basement and crawl space still need internal protection. These areas are vulnerable to water damage because they sit below ground level, surrounded by moisture-rich soil.
Exterior waterproofing keeps water out – but the best protection comes from combining it with internal solutions that manage moisture from the inside. At Crawl Space Ninja, we recommend a comprehensive moisture management approach.
- Installing vapor barriers to block ground moisture
- Using dehumidifiers to control indoor humidity
- Sealing crawl space vents and walls to prevent condensation
- Adding sump pumps and other interior drainage systems as needed
- Insulating and air sealing to reduce temperature fluctuations that lead to condensation
