We've worked with everyone from homeowners to the Smithsonian Institute. Our team treats each workspace with respect and care, leaving the space cleaner and DRYER than when we arrived. Mid-Plains Waterproofing is a professional sub-grade/ basement waterproofing company and certified installer of EZ Breathe Ventilation Systems, the most advanced clean-air machines available today. Founded in 1998, Mid-Plains quickly became the most respected waterproofing company in the area. We guarantee our work for longer, and our technique is better than any other on the market today.
