Zak's Commercial and Zak's Building are now using screw piles for both commercial and residential buildings. This new technology drastically reduces the time necessary to set a base before construction begins or before we bring in one of our beautiful RTMs. Screw piles are foundation structures that act like footings that can handle the weight of even large industrial buildings. http://www.zaksbuilding.com/Saskatchewan-Construction/Screw-Piles
