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 usable is if it remains dry year-round.

Ideally, a basement should be designed and constructed with a waterproof foundation; however, that is not always the case. NIJAC Roofing and Insulation provides foundation waterproofing in Sioux Falls, South Dakota and the surrounding regions.


Waterproof Your Foundation

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