| Post-Tech PT Cable Drying is an economical corrosion mitigation solution for unbonded post-tensioned cables encased in push-through or heat sealed sheaths. The process purges moisture from the cable by cyclically pressurizing a dry, non-corrosive gas such as air or nitrogen into the cable sheath. The process continues until the full length of the cable is dry. PT Cable Drying is typically a single treatment that can be adapted for permanent installation when the source of moisture ingress cannot be eliminated. Performance can be monitored manually or by means of electronic sensors installed for remote off-site monitoring and control.

sealed sheaths.
- PT Cable Drying purges moisture from the cable by cyclically pressurizing a dry, non-corrosive gas such as air or
nitrogen into the cable sheath.
- Process ensures that cable conditions are dry at the end of the treatment.
- System can be adapted for temporary or permanent installation depending on severity and situation of cable corrosion.
- Performance can be monitored manually or by means of electronic sensors installed for remote off-site monitoring and control.
