A Quick Overview

- Exterior waterproofing involves excavation and higher costs, whereas interior waterproofing is more affordable and minimally invasive.
- Exterior waterproofing provides durable, long-term protection, while interior waterproofing requires regular inspections and maintenance.
- Exterior waterproofing protects the foundation from structural damage, while interior waterproofing doesn’t address the root cause of water intrusion.
- Exterior waterproofing is ideal for new constructions, homes in high water table areas, or regions with heavy rainfall. Interior waterproofing suits existing homes with limited exterior access or a smaller budget.

Interior vs Exterior Basement Waterproofing
Here’s a comprehensive view of the differences between exterior and interior waterproofing.
Exterior Waterproofing
With exterior waterproofing, the goal is to stop moisture far before it can reach vulnerable spots in your house.
Exterior waterproofing is more expensive than interior waterproofing due to the large amount of work required. Excavation can be necessary, often requiring heavy equipment. However, exterior waterproofing is generally more effective than interior solutions. It prevents water from reaching, and weakening, the foundation of your home.
Some elements of exterior waterproofing include:
- Removing the earth away from basement walls
- Cleaning and recoating the walls
- Updating the existing drain tile
- Fixing foundation cracks

Advantages
- Foundation Protection: Shields the foundation from water infiltration, reducing long-term structural damage.
- Longer-Term Solution: Provides a durable barrier against water.
- Enhanced Property Value: Improves your home’s value by safeguarding its foundation.
Disadvantages
- High Cost: Typically more expensive due to labor and material requirements.
- Disruption to Landscaping: Excavation can damage gardens, patios, or other outdoor features during installation.
- Weather Dependent: Installation may be delayed by rain or other adverse conditions.
- Limited Accessibility: Homes with tight spaces around the foundation may face challenges, and incorrect installation can harm the structure.
- Time-Consuming: The process can take weeks to complete, depending on the property size and conditions.
Ideal Use Cases
- New constructions as waterproofing can be integrated easily.
- Homes in high water table areas and regions with heavy rainfall.
Interior Waterproofing
The goal of interior waterproofing is to remove moisture from inside your home.
Interior waterproofing is often a last defense effort against moisture that’s breached the exterior foundation. One of the nice things about interior waterproofing options is that they are often inexpensive and some are even able to be DIY jobs.
Some elements of interior waterproofing include:
- Diverting water from the foundation toward the sump pump
- Handling hydrostatic pressure that exists under the basement

Advantages
- Cost-effective: Typically more affordable compared to exterior waterproofing.
- Minimally Disruptive: Does not require excavation or major disruptions to the property.
- Quick Installation: Can be completed in a shorter time frame.
- Enhanced Property Value: Improves the value of your home.
Disadvantages
- Doesn’t Address The Cause: Manages water after it enters, rather than preventing it.
- Requires Regular Maintenance: Needs consistent inspections and maintenance to prevent clogs.
- Limited Structural Protection: Does not protect against exterior flooding or foundation damage.
- Limited Property Value Enhancement: Adds less value compared to exterior waterproofing.
Ideal Use Cases
- Existing buildings where exterior access is limited or excavation is not feasible.
- You have a limited budget.
Factors to Consider
When choosing between interior vs exterior basement waterproofing for your home, it is critical to consider a series of factors to make an educated decision.
1. Location
The location of your property plays a key role in choosing between interior and exterior basement waterproofing. Homes in regions with high water tables or frequent heavy rainfall present a higher risk of water damage. In these cases, a comprehensive solution combining both interior and exterior waterproofing is ideal.
2. Space
Exterior waterproofing requires significant excavation around the foundation to install drainage systems. This process is not feasible in properties without enough space. In this case, interior waterproofing would be the better choice.
3. The Intended Use of Your Basement
If your basement serves as a living space or home office, exterior waterproofing provides a more permanent solution for maintaining a dry, comfortable environment. For basements used primarily for storage, interior waterproofing may be a more adequate, cost-effective option.
4. The Invasiveness of the Project
Exterior waterproofing projects are typically more invasive, involving heavy equipment and extensive excavation. Interior waterproofing is less disruptive as exterior excavation is not required.
5. Durability and Maintenance
Exterior waterproofing systems often last longer as they address the root cause of water intrusion. Interior systems may require more frequent maintenance or replacement of components, such as sump pumps, to remain effective over time.
In addition to that, the quality of the materials used for both methods also impacts the long-term durability of the systems installed.
6. Your Budget
Exterior waterproofing is generally more expensive due to excavation and labor-intensive processes. Interior waterproofing is typically more budget-friendly, making it more attractive for homeowners with low budgets.
Risks of Not Waterproofing Your Home
Failing to waterproof your basement can lead to significant issues that compromise your home’s safety and value.
- Flooding: Water intrusion can damage your foundation and personal belongings, leading to costly repairs.
- Insect Infestations: Damp environments attract pests like centipedes, mold mites, and crickets.
- Mold: Persistent moisture promotes mold growth, which poses serious health risks.
- Additional Costs: If a home inspector finds flooding, mold, or water damage, you may need to address these issues before selling your home.
