Saving the Morris Island Lighthouse One Staircase at a Time

MORRIS ISLAND, SC – Built in 1876 and standing 161 feet tall, Morris Island Lighthouse was decommissioned in 1962 and placed on the national register of historic places in 1982. After the decommissioning, the structure’s circular staircase was showing advanced deterioration due to the salt air environment and in danger of collapsing in on itself.

Enter CINTEC North America and a solution for stabilizing the staircase with CINTEC cementitious grout anchors. The anchors were tied to the inner and outer walls of the lighthouse. A beam was then tied to the anchors and the staircase was tied to the beam. CINTEC provided the anchor system to support the staircase while engineering and installation of the system was managed by ICC-COMMONWEALTH.
