Concrete and Steel Repairs at a Mining Facility After more than 60 years of salt mining, the facility had suffered significant deterioration, requiring extensive concrete and steel repairs. Walls, columns, beams, and secondary structural members showed severe signs of damage, including efflorescence, spalling, steel loss, and overall structural degradation. The environment inside the mine had taken a heavy toll on the structure. The proximity to Lake Huron made it vulnerable to harsh storms, leading to high moisture levels and extreme cold. Combined with the salt production process, this created a perfect storm for chloride ion migration, causing rebar to swell and pop, which led to concrete spalling and further structural issues. This image captures the extent of the damage—efflorescence, spalling, and structural degradation were clearly visible throughout the facility. This photo shows the application of CarbonSeal carbon fiber before the topcoat was applied, highlighting the initial stages of the repair process. Here is the completed CarbonSeal system with the topcoat fully applied to beams, slabs, and walls. HJ3 engineered a custom composite fiber system to restore lost tensile strength and shear reinforcement in the external walls, targeted columns, and internal supports. This advanced solution successfully repaired and strengthened 9,800 square feet of surface area using 20,000 square feet of carbon fiber, significantly extending the life of the facility by up to 30 years. At HJ3, our team of experienced engineers specializes in creating tailored structural solutions that meet the unique needs of each project.
