1. A post-tensioning system, the system comprising:
an anchor member;
a pocket-former member comprising a first end and a threaded second end;
a bolt member comprising a first end, a threaded second end, and a flange; and
a cold shrink member;
wherein the anchor member further comprises a tube end and collar distal to the tube end that includes a first anchor coupler;
wherein the first end of the pocket-former member further comprises a second anchor coupler, and is configured to removably engage the first anchor coupler;
wherein the threaded second end of the pocket-former member is configured to removably engage the threaded second end of the bolt member; and
wherein the cold shrink member comprises an elastomeric material pre-expanded over a removable dilator, and wherein removal of the dilator allows the cold shrink member to contract around the tube end.
