Choosing Your Basement Waterproofing Method

Posted on: 28 September 2017

When you have to decide about waterproofing your home, you have two choices. You can opt for interior or exterior waterproofing. In order to understand which is best for your application, you need to understand the differences between them. Here's a look at what you need to know about both before you decide to treat your basement:

Interior Waterproofing Basics

Though it's called waterproofing, interior waterproofing is more of a water blockade, because it forms a barrier inside that blocks water after it has already gotten into the foundation. While this does keep water out of the basement itself, it doesn't protect the walls or the foundation from erosion or frost since it allows water to enter the basement walls from the outside and just diverts it away afterward.

When Is Interior Waterproofing The Best Option?

If you have elaborate landscaping outside your home that you don't want to disturb, you may want to avoid doing any work around the outer foundation. You need to be sure that the walls and foundation are structurally sound before you opt for a treatment like this.

It's usually a temporary treatment to manage smaller leaks or when you want to prevent a leak until you're ready to fully excavate and treat the exterior walls. You should follow it up with exterior waterproofing when you're able.

Exterior Waterproofing Basics

Exterior waterproofing is more extensive. It requires excavation to expose the foundation of the house. Once everything is cleared out of the way, the exterior wall needs to be thoroughly cleaned. It needs to be either free of any cracks or it needs to be patched before you can seal it. Then, the outside walls are treated with a waterproofing sealant. Once that's applied, drainage tiles are placed along the side of the foundation.

The advantage of exterior waterproofing is that it preserves the complete structural integrity of the home because water cannot enter the foundation or the basement walls. This eliminates the risk of frost damage or erosion that can weaken the structure.

When Is Exterior Waterproofing The Best Option?

Exterior waterproofing is the treatment of choice whenever possible. It is the preference when you have cinder blocks or aged concrete. You'll also want to consider exterior waterproofing if you have stone or brick construction.
