APPLICATION REPORT
KDOT Bridge Pier Repair
Customer: Kentucky Department of Transportation
Location: Cumberland Lake Bridge Pier, Somerset, KY
Problem: The Kentucky DOT was forced to lower the water level on Cumberland Lake to rebuild the dam. Serious concrete washout was discovered on portions of the bridge pier supports that were previously submerged under water. The bridge engineers needed to repair the damaged concrete and provide a water-tight seal.
Solution: Use Phoscrete Concrete to create a structurally sound repair and a water-tight seal by chemically bonding to the existing concrete.”

Material Used: Phoscrete 601-P
Savings Using Phoscrete: Permanent water tight repairs were made in several hours.
Method of Installation: Hand Ramming
Equipment Used: Pontoon Boat, hammer/concrete chisels, leaf blower, portable generator, electric drill motor w/paddle type mixing blade and standard concrete hand tools.
Scope of Work: Access to the supports was made on a fully equipped Pontoon Boat that was tied off to the piers. Weak concrete was removed by a hammer and chisel; the holes were blown clean with an ordinary household leaf blower, Phoscrete 601 dry-aggregate and pre-measured liquid activator was mixed in 5 gallon pails and hand rammed into all repair locations. Final surface finishes were completed with a concrete hand trowel.
Installation Date: October 2008
Follow Up: July 2009: The repairs remain intact and unchanged from the date of installation. However, dam repairs will continue throughout 2010 and the Phoscrete repairs remain above the water line. The bridge engineers are pleased with the Phoscrete repairs and will specify Phoscrete for all future bridge pier support repairs.
