Western was contacted to review the condition of an existing 500’ long concrete barrier wall at the Federal Reserve Bank in Minneapolis. The structure experienced multiple vertical cracks and various signs of deterioration. Western injected 750 lineal feet of vertical cracks in the concrete structure to essentially “bond” the wall back together to prevent further deterioration. The cracks were prepared for injection by mechanically grinding and surface mounting ports over the existing cracks. The cracks were then buttered with Sikadur 31 gel epoxy and the ports were injected with Sikadur 52 structural epoxy. Once the material had cured, the excess epoxy was ground off and the ports were removed; the structural strength had been restored to the wall. A protective waterproof elastomeric coating was applied over the entire concrete surface to add years of protection and resistance to the elements.
