Posted by Jeff Steiber on November 27, 2018

At Brennan, we work on dams of various sizes and functions. Very few new dams are built each year, so most of our work consists of rehabilitation and repairs. Dams are built to last for long periods of time, however certain components require periodic repairs and replacements. Radial gates, often referred to as Tainter gates, consist of components most commonly in need of attention. In our experience, we have found certain best practices that will increase the longevity of these gates, as well as increase their functionality.
