Salt Barn Wall Failure Repairs
After a winter with below average snowfall, the City of Cambridge, Ohio was left with an excess of road salt on hand. Due to their salt contract obligations, they were required to take on additional quantities of salt the following year in preparation for the upcoming winter. This left their salt storage overly full and resulting in damage to the structure.
Cracks formed along the back of the structure and the back wall began to tip outward. Material was placed on the exterior of the structure to stop this movement and steel strapping was installed in an attempt to stop the cracks from widening.
The city’s maintenance crews came up with an extensive repair plan that involved new walls being poured to brace the failing wall. When the City Engineer was consulted by the maintenance crews to review the repair plan, he reached out to Rhino Carbon Fiber for an alternative solution utilizing CFRP. Rhino’s Engineer visited the site and discussed the possible solutions with City personnel. It was recommended that the cracks be patched with a non-shrink repair mortar, then reinforced with Rhino’s Concrete Crack Lock. Once this was complete, the corners would be wrapped with CFRP for additional support.
The City ended up choosing the CFRP solution over the repair method previously considered. Their maintenance crews were able to complete the repairs in a matter of days, at a cost much less than that of forming and pouring new walls. Rhino was brought on board in October and the quick response and immediate material availability enabled the repairs to be completed prior to temperatures falling and the salt barn being put back into use.
