Two Types of Waterproofing

There is not just one type of waterproofing. There is interior waterproofing and exterior waterproofing. They both have their own set of pros and cons. Interior waterproofing may be the best option for one type of home and exterior basement waterproofing may be better for another. In order to decide what type of basement waterproofing is best for you and your home, you need to understand the differences between interior and exterior.

Exterior Waterproofing

Exterior waterproofing is the first line of defense when keeping water out of your home. Exterior waterproofing has a few different components to it: Gutters, downspouts, and grading. It is always crucial to make sure your gutters are clean and not filled with debris. Otherwise, water will not be able to properly drain. Another part of exterior waterproofing is the application of a waterproof membrane. This is applied around the foundation of one’s home to seal any cracks that could allow water and moisture through. Previously we have mentioned french drain systems. These are also considered a part of exterior waterproofing. In order to install a french drain, the foundation of one’s home must be unearthed. Then drain tiles will be placed in a trench, that has been dug around your home’s foundation. The tiles will then be covered with tile and then completely covered with soil. This process is a little longer and more pricey, but definitely worth it. These systems will take water away from your home, preventing water from even entering your basement. Exterior waterproofing is a great option for many individuals. It works to prevent any water from entering your basement. It is important to consider that this is a more expensive option. Also, not all homes can utilize this method due to proximity to other buildings.

Interior Waterproofing

The main difference between these two waterproofing types is that exterior waterproofing prevents water from entering the basement. Whereas, interior waterproofing works to reroute water that has already entered your basement.

Interior waterproofing systems often include pipes, drains, sump pumps, and dehumidifiers.

The pipes and drains installed are used to capture any excess groundwater. This water is taken through the pipes to the sump pit. This is a large trench that collects all of the excess water from your basement. There is a sump pump inside of this basin. This pump pumps the water out and away from your home before it can cause detrimental damage.

Vapor barriers are also used in interior waterproofing. These consist of plastic or foil protective sheeting, which is placed along walls. The goal of this is to seal out extra moisture. Dehumidifiers are also used to keep excess moisture out of your basement’s air.

Interior waterproofing is often cheaper than exterior waterproofing methods. However, it is important to remember, interior waterproofing is more so water management. It does not prevent water from coming into your basement. Interior systems work to remove the water that has already entered your home.
