Below grade waterproofing Application

Below-grade waterproofing is the construction process of applying coatings and membranes to the walls of a building’s foundation below ground level. When pairing effective, below-grade waterproofing with water management techniques, it keeps the below-grade building envelope leak-free and reduces life-cycle costs immensely.

Whats the reason this is needed? Concrete and shotcrete are porous materials, and over time, they can crack once the building has settled or from water-exerting pressure on the below grade foundation. If a building is built on a site with underlying contamination, hazardous conditions can be created when methane gas, or vapors contaminated soil and groundwater can migrate through concrete imperfections.

If you place a barrier between the concrete and the surrounding earth, it can prevent water infiltration and resist harmful contaminants from entering the structure — if the barrier is robust enough. That’s why finding a high-quality below-grade waterproofing product is so important.

During the construction, a successful below grade waterproofing system will include a combination of effective drainage and impervious membranes applied on the foundation.

There’s a variety of perimeter drain systems that can be applied. Which is best for your building depends on factors like:

• the ground slope around the foundation

• the type of soil

• irrigation systems used on landscaping

• the material that the building foundation was made from

• the design of the building
