Cintec North America announces its cementitious grout anchors were used in a project for the stabilization of the deteriorating staircase in the Morris Island Lighthouse, located on Morris Island, South Carolina.
The lighthouse was opened in 1876 and decommissioned in 1962. The structure is 49 meters and 161 feet tall. The lighthouse was placed on the National Register of Historic Places in 1982. After the decommissioning, the circular staircase was showing advanced deterioration due to the salt air environment. There was a real fear that the staircase would collapse in on itself.
The stabilization on the staircase included the installation of Cintec cementitious grout anchors. The anchors were tied to the inner and outer walls of the lighthouse. A beam was tied to the anchors. The staircase was tied to the beam to support it. Cintec America provided the anchor system to support the staircase. ICC Commonwealth, based in Buffalo, New York, was responsible for the engineering and installation.
The project anchor specification was 1 3/8 inches (35 millimeters) via stainless steel rebar grade 2205 - 44 inches (1,118 millimeters) long-socked 41 inches (1,040 millimeters) with 3 inches (75 millimeters) of exposed threads to attach the bracket to the beam.
