Our engineers perform a wide range of commissioning, corrosion testing and inspection services for our customers. Our NACE-certified professionals are knowledgeable in the latest corrosion testing technologies and are ready with state-of-the-art instruments and test equipment.
We typically perform commissioning services with every cathodic protection project. Because corrosion is a time-dependent process, having good baseline data at the time the cathodic protection system is installed is critically important when evaluating a system’s operation several years later. Our commissioning report provides the client with a thorough baseline data set, which provides a valuable reference point in future years.
Regular cathodic protection system inspection and testing should be performed to assure the proper operation of the cathodic protection system. Should operating conditions change, the proper inspection and testing program will identify the effect of these changes on the cathodic protection systems operation and help determine the need for additional protection.
Often, simple adjustments can be applied to the cathodic protection system, eliminating the need for costly modifications or upgrades. This is especially true for impressed current cathodic protection systems, which are generally designed with some level of excess capacity. With galvanic systems, special care must be taken to assure that the structure being protected is isolated from other nearby structures. Testing of galvanic cathodic protection systems frequently results in the identification of isolation flange failures that can be easily fixed, restoring the cathodic protection system to proper working order.
We provide a full range of testing including:
- Close interval surveys (CIS)
- Alternating current voltage gradient (ACVG)
- Direct current voltage gradient (DCVG)
- Pipeline current mapper (PCM)
- Soil resistivity surveys
- Guided ultrasonic wave (GUL)
Other Tests:
- Delamination surveys
- Full petrographic analysis
- Depth of cover
- Transit systems
- Concrete strength-compression
