Causes of Bridge Pier Staining
Four types of bridge stains exist in Arkansas: Rust stains - those stains directly traceable to rust; red stains - broad stains which are not directly traceable to rust; gray stains - similar to red stains except for color; and graffiti. Bridge stains in Arkansas cause no significant structural damage; they do not accompany a deterioration of aggregate. Red and gray stains, which comprise over three-fourths of all stain on most bridges, can be effectively removed by sandblasting, washing with soap, water and a brush, or application of certain acids then rinsing. Stains on new structures can be greatly reduced by eliminating or sealing expansion joints above bridge piers. (Modified author abstract)
