Exterior waterproofing gets classified as an essential preventive measure that restricts the flow of water from entering the home's basement and even free space. However, its overall process is quite different from interior waterproofing methods and works to prevent water from entering in the first place.
The exterior waterproofing involves digging out the dirt from the basement walls. It also includes applying a moisture barrier and installing a specially designed dimple board that can divert water from the wall.
