Mining facility concrete and steel repairs.

Over 60 years of salt mining had deteriorated this facility which required concrete and steel repairs. Walls, columns, beams and secondary members had significant efflorescence, spalling, steel loss and structural degradation.

Significant efflorescence, spalling, steel loss and structural degradation
The facility, located near Lake Huron, is susceptible to severe lake storms creating excessive moisture and extreme cold. The salt production environment causes significant chloride ion migration, rebar swelling/popping
and subsequent concrete spalling.

HJ3 engineered a composite fiber system to replace the lost tensile strength and shear reinforcement in the external wall, targeted columns, and internal supports. The CarbonSeal™ repair restored the strength of the facility, repairing and strengthening 9,800 sq ft surface area with 20,000sq ft of carbon fiber, extending its life by up to 30 years.
