Dams

Rising above the rest, Thalle’s dams are some of our proudest achievements.  The Dam segment encompasses many scopes of work and Thalle has performed all scopes of dam construction for decades.  Thalle is an industry leader in the construction of new RCC and earthen structures as well as restoration of existing dams and spillways. 


This diverse segment also includes construction of intake and outlet works, dewatering, instrumentation, primary and emergency spillways, electrical and mechanical requirements and site restoration.  Much of our completed work has benefitted communities by improving dam safety and reducing the risk of dam failures, flooding and loss.  Thalle is a proud member of the Association of State Dam Safety Officials and maintains constant engagement with this group of leading authorities on dam safety. 


Our knowledge of the latest technology in dam safety has allowed us to construct the second piano-key wier spillway in the United States, dramatically increasing the spillway capacity without expanding the length of the spillway opening.
