Retaining Walls - We are the proven leader in earth retention systems, whether temporary or permanent. Whether steel sheeting, H-Pile/Lagging, or one of our variations of that system. At Irondale High School in Arden Hills, Minnesota, we recently completed a permanent retention system consisting of steel pipe screwed into the ground to minimize vibration. The steel pipe were used as the soldier pile with treated wood lagging and screw anchor tiebacks.
