Basement waterproofing generally lasts anywhere from 10 to 20 years. However, there are many factors that can affect how long it lasts, such as the quality of the installation, the type of waterproofing material used, how well it is maintained, and the environment in which it is used. For example, if a basement is constantly exposed to moisture or water infiltration, then the waterproofing will not last as long as if it were used in a drier environment.

It will depend on the quality of the Basement Waterproofing and how well it is installed. A good quality Basement Waterproofing should last 10-20 years. If it is not a quality product or if it is not installed properly, it may only last for a few years.
