When it comes to protecting your Home from water damage, waterproofing is an absolute necessity. It’s not a matter of if, but when your home will experience moisture issues. Waterproofing your home can also increase its value and prevent costly repairs. However, before you can start waterproofing your home, you need to understand the differences between exterior and interior waterproofing services. In this article, we will compare the differences between exterior and interior waterproofing services and help you determine which approach is best suited for your specific needs.
What is Exterior Waterproofing?
Exterior waterproofing involves the application of a waterproof barrier to the exterior of your home’s foundation. This method of waterproofing is effective in preventing water from seeping through the walls and causing damage to your home. The process involved in exterior waterproofing is as follows:
-
Excavation: This involves digging up the soil around your home’s foundation to expose the exterior walls.
-
Repair and Replacement: Any damaged or weakened areas in the foundation are repaired, and any weeping tiles are replaced.
-
Cleaning: The exterior walls are cleaned to ensure good adhesion of the waterproofing membrane.
-
Waterproofing: A waterproofing membrane is applied to the exterior walls, along with a drainage board and dimple mat.
-
Backfilling: The soil is replaced and compacted to ensure proper drainage away from the foundation.
What is Interior Waterproofing?
Interior waterproofing involves the application of a waterproof barrier to the interior walls of your home’s foundation. This method of waterproofing is effective in preventing water from seeping through the walls and causing damage to your home. The process involved in interior waterproofing is as follows:
-
Floor Removal: The concrete floor is removed from the basement to expose the interior walls.
-
Cleaning: The interior walls are cleaned to ensure good adhesion of the waterproofing membrane.
-
Waterproofing: A waterproofing membrane is applied to the interior walls.
-
Installation of Drainage Tiles: Weeping tiles are installed inside the basement to collect any water that seeps through the walls.
-
Backfilling: The floor is replaced with gravel and then concrete.
Differences between Exterior and Interior Waterproofing Services
Both interior and exterior waterproofing methods have their advantages and disadvantages. Here are the main differences between exterior and interior waterproofing services:
Installation Time
Exterior waterproofing is a more time-consuming process than interior waterproofing. The excavation alone can take several days, and the backfilling process can take at least a day. On average, exterior waterproofing takes approximately two weeks to complete. In contrast, interior waterproofing can be completed in a matter of days.
Cost
Exterior waterproofing is generally more expensive than interior waterproofing. The cost of excavating the soil and applying the waterproofing membrane to the exterior walls can add up quickly. In contrast, interior waterproofing is a less invasive process and, therefore, less expensive.
Effectiveness
Both interior and exterior waterproofing methods are effective in preventing water from seeping through the walls and causing damage to your home. Exterior waterproofing, however, provides a more comprehensive solution as it addresses the problem at its source. Interior waterproofing, on the other hand, is effective in controlling water that has already seeped into your home.
Longevity
Exterior waterproofing is designed to last for several decades, whereas interior waterproofing requires regular Maintenance to remain effective. Due to its comprehensive nature, exterior waterproofing is less likely to require future maintenance.
Which Approach is Best Suited for Your Specific Needs?
The approach that is best suited for your specific needs depends on several factors, such as your budget, the severity of your water issues, and your long-term goals.
If you are experiencing water issues that require a comprehensive solution and have the budget to support it, exterior waterproofing is the best solution. This method of waterproofing provides long-term protection and ensures that your home is protected from water damage for several decades.
If your budget is limited, and you are experiencing minor water issues, interior waterproofing may be the best solution. While it is not as comprehensive as exterior waterproofing, interior waterproofing provides a cost-effective solution that addresses the issue at its source.

Conclusion
Waterproofing your home is essential to protect it from water damage and prevent costly repairs. Understanding the differences between exterior and interior waterproofing services is crucial in determining which approach is best suited for your specific needs.
