Prevent water intrusion through any floor or wall



Waterproofing is one of the most critical applications for any surface. This is true for roof decks, bathrooms, showers, pools and many other applications. Semco’s integral waterproofing system has been tested under extreme conditions to be able to withstand water pressure even while being physically stretched. These properties allow the underlying performance to work while the surfaces aesthetic beauty is maintained.

Concrete block is extremely porous. It acts like a sponge for moisture and has to be waterproofed to prevent moisture from entering into a home or building. Waterproofing the ‘dry’ side of a foundation or wall is referred to as negative-side waterproofing. Its major goal is to provide a barrier coat that prevents water from seeping through the wall and keeping the area dry.
