Many people think of “waterproofing” as anything that keeps water out. In construction, waterproofing generally refers to components that keep water out of below-grade structures. A more specific definition is systems or components that resist hydrostatic (water) pressure below-grade. Waterproofing differs from damp-proofing in that waterproofing is intended to resist hydrostatic pressure, whereas damp-proofing is only intended to help shed moisture and resist water vapor.
There are generally two types of waterproofing: vertical and horizontal. Waterproofing systems must do two things successfully: resist hydrostatic pressure and survive construction.
This all seems straight forward. So why should I consider hiring a waterproofing consultant? A waterproofing has the knowledge and experience to integrate below-grade waterproofing with the remaining building components so that all perform effectively. A waterproofing consultant can also provide critical quality assurance during design and construction to provide additional assurance that installed waterproofing is installed and protected during the construction process.
