| Early identification and mitigation of corrosive conditions can significantly reduce the costs of major repairs and the risk of structural failure. As part of an overall assessment of the condition of post-tensioned structures, a Post-Tech® PT Corrosion Evaluation of heat sealed or push through cables is recommended to gain an understanding of the structure, determine the cause and extent of the problem, and to assist in the preparation for corrosion mitigation.
Post-Tech Corrosion Evaluation is a non-destructive method of testing that can assist engineers and building owners in the assessment of overall cable conditions. The PT Corrosion Evaluation determines the degree of wetness inside a cable sheath by injecting dry gas or air and measuring the moisture content in the exhaust from the venting ports. There are two approaches for PT Corrosion Evaluation; Pilot Project and Full-Scale testing.
Features and Benefits
- A non-destructive test used to identify heat sealed or push-thorough cables exposed to a “wet” or potentially corrosive environment
- Determines the degree of wetness inside a cable sheath by injecting dry gas or air and measuring the moisture content in the exhaust from the venting ports.
- Identifies the probable extent of current of future corrosion deterioration
- Access areas used as “IN” ports can also allow for visual observation and testing.
