Falling into disrepair after years of neglect, the Ashtabula Lighthouse, Ashtabula, Ohio, was ready for restoration. Since acquiring control of the property in 2005, the Ashtabula Lighthouse Restoration and Preservation Society has been working diligently to restore the lighthouse originally built in 1876.

ProSpec, a Bonsal American product, is donating its concrete repair material, Metro Mix 240 AE, to assist with the restoration. One of the first efforts for restoration was to repair the lighthouse's concrete deck. Because the lighthouse sits more than a mile out in Lake Erie, ready-mixed concrete was not an option. The concrete repair material, which is available in 80-pound bags, offered a solution to the situation. The material was used for the lighthouse deck repairs, which ranged from 2 to 4 inches deep, because it is a superplasticized concrete mix—engineered for structural and full-depth repairs. The product also can be used for deeper repairs with the addition of aggregate.

The project required a product that could withstand northern Ohio's extreme freeze/thaw cycles and combat water intrusion. Because Metro Mix 240 AE is air entrained, it has improved freeze/thaw resistance to prevent further delamination around the concrete base of the lighthouse. Its integrated corrosion inhibitor helps prevent water intrusion on the deck from causing additional spalling.

“The lighthouse has always been a landmark for the community and for the harbor,” says Lloyd Bogue, owner of Bogue Construction Co. Inc. and vice president of the Ashtabula Lighthouse Restoration & Preservation Society. “The goal is to restore it to its previous condition and educate the community on its importance. The concrete repair material performed beautifully in repairing the deck.”

The restoration project is scheduled for completion by summer 2009.
