Certified Foundation Waterproofing

A Dry Basement is Just a Phone Call Away

A finished basement can double the living space of a home, adding much-needed bedrooms, a family room, storage, or laundry areas. Of course, the only way for a basement to be truly useful is if it remains dry year-round. That’s why you should install Foundation Waterproofing!

Ideally, a basement should be designed and constructed with a waterproof foundation; but, that is not always the case. Although, thanks to NIJAC Roofing and Insulation you can receive foundation waterproofing services in the Sioux Falls, South Dakota area.


Waterproof Your Foundation

Utilizing the Rub-R-Wall or Rub-R-Wall Plus Waterproofing process, NIJAC will spray your foundation with a 100% seamless membrane. That membrane will prevent water from entering your basement. As a result, this protects occupants and your belongings from the ill effects of moisture seepage.
