Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Scour, caused by swiftly moving water, can scoop out scour holes, compromising the integrity of a structure.

Guardian Retention Systems offers many different solutions to bridge scouring issues.  Figure 1 shows a combination repair to the bridge concrete slope, and the bridge piers for both structures.
