The Table Rock Reservoir is located in a remote part of South Carolina. Exposed to the elements, the control and expansion joints in the spillway had to be replaced. Those joints ran transversely across the spillway as well as two longitudinal joints that ran up each side.
Most of the 2,200 lineal feet of joint that had to be replaced also required new nosing material at the joint shoulder. Western utilized Sika 42 Grout Pak P.T., a three component epoxy mortar to rebuild the nosings of the joints. Sika’s CombiFlex System was used for both the control and expansion joints.
