We may even wonder whether the bridge is safe. But when it comes to the safety and integrity of a bridge, there is much more at work than what we see above ground. A structure is only as good as its foundation. Beyond the superstructure, how do we ensure the strength and stability of a structure's foundation? One effective solution: **helical piles.** [Read More](https://www.jfbrennan.com/blog/helical-piles-101-strengthening-foundations) [**{count-facebook}](https://www.jfbrennan.com/blog/topic/bridge-pier#)[**{count-twitter}](https://www.jfbrennan.com/blog/topic/bridge-pier#)[**{count-linkedin}](https://www.jfbrennan.com/blog/topic/bridge-pier#)[**](https://www.jfbrennan.com/blog/topic/bridge-pier#) [![](https://www.jfbrennan.com/hubfs/Scour%20Header%20Blog%204.jpg) ](https://www.jfbrennan.com/blog/effective-solutions-for-underwater-scour-repair) ## [Effective Solutions for Underwater Scour Repair](https://www.jfbrennan.com/blog/effective-solutions-for-underwater-scour-repair) Posted by [Dillon Hogan](https://www.jfbrennan.com/blog/author/dillon-hogan) on February 21, 2018 According to the United States Department of Transportation, underwater scour is the leading cause of bridge failure, ahead of collisions and overloading. Scour is the erosion or removal of a streambed or bank material from bridge foundations due to flowing water. As many bridges sit over water, the potential dangers of scour cannot be ignored. There are many solutions to scour problems. However, there are two options that we find the most effective.
