Moisture in your basement means it's time to consider waterproofing measures. Interior waterproofing options include applying an interior membrane to the basement wall, along with installing a sump pit, pump, and drain system to move water out of the basement. The following can help you decide if interior waterproofing is the right option for your home.
1. Moisture Origin
The origin of the moisture in the basement must play a factor in any waterproofing decision. Moisture can come from a high water table pressing against the basement wall, from condensation originating inside the basement, or from seasonal flooding. Interior waterproofing doesn't work well in high water table situations, but it can prevent wall damage from interior condensation. It can also be effective against minor seasonal moisture issues.
2. Backup Protection
Homes that already have exterior waterproofing may sometimes need additional protection from either interior condensation or seasonal moisture issues that put additional pressure on the existing waterproofing. Interior waterproofing provides a simple way to give this extra protection, thus extending the life and effectiveness of the other waterproofing methods in use.
3. Landscape Concerns
One major issue with exterior waterproofing measures is that heavy excavation is necessary around the perimeter of the foundation so that the waterproofing membrane can be put in place. This can destroy the landscaping, which takes money and time to fix. Interior options result in little to no disturbance of the landscaping around your home, making them a viable solution if your yard is a concern.
4. Application Speed
The excavation necessary for exterior waterproofing also means it takes more time to complete the process. This can be a concern, especially if you need a solution prior to an imminent wet season. Interior waterproofing methods can typically be implemented in a much shorter time frame. Wall barriers, for example, can be applied in a day or two. Even drainage systems tend to take less time to install than exterior membranes, since they don't require extensive excavation.
5. Budget Constraints
Finally, the budget must be factored into your decision. Exterior waterproofing tends to be more expensive. Costs include the use of heavy equipment and excavation, along with additional labor charges since the process tends to take longer compared to interior options. There are also post-installation costs to consider, such as landscaping recovery. Overall, interior waterproofing options, particularly membrane applications, tend to be less expensive.
