Project:     Belleville Locks & Dams
Location:   Reedsville, Ohio
Owner:      U.S. Army Corps of Engineers

The Belleville Locks and Dams project is phase one of three phase project awarded to Jean’s Waterproofing, Inc. (JWI) by the U.S. Army Corps of Engineers (ACOE).

ACOE inspectors discovered a considerable large amount of cracks in crossovers and riser spaces at the Belleville site.  The site consists of two (2) locks on the Ohio River.  The main lock is 1,200 feet long with a width of 100 feet and is complimented by a 700 feet by 100 feet auxiliary lock.

The riser and crossover provide access to varios water, air and hydraulic lines that are used in operating four sets of gates.  Inspectors marked control joints and random cracks in the crossovers and risers that needed to be sealed.  The majority of leaks appeared to originate in their riser control joints.  These control joints would prove to be the most challenging leaks to inject and seal.

The risers are 8 feet by 6 feet in depth and adjacent to the gate hinges.  They are connected at the bottom by a 100 foot long, 8 foot by 6 foot crossover tunnel.  Starting from the top of the risers, cracks were chased with 4 inch grinding wheels and any prior foam was removed from all wall surfaces.  A fast set cement was applied to the cracks and 1/2 inch holes were drilled every 6 to 8 inches apart.  Packers were installed and the injection was done with a water-swelling, acrylate-ester resin using a two-component pump.

Each phase was carefully scrutinized by the ACOE and each was declared a success.
