Box culvert and weir repair near wetland

The City of Tallahassee had a problem with a street running over a box culvert at Black Swamp. Following several heavy rainfalls, a dip in Park Avenue developed. Eventually, the depression grew so pronounced that it became a traffic hazard.

City crews attempted to fix the problem several times using different methods, including replacing a section of pavement and its subgrade, and chemically grouting the culvert joints with an epoxy-based grout. These repairs did not work, however. Settlement of the roadway continued. Officials suspected that the culvert joints were leaking, so they considered completely removing the roadway to expose the box culvert. This option was very expensive and difficult. Read the case study to learn how chemical grouting saved the city money, disruption and environmental impact.
