Static Load Testing

PMC pioneered data-logging techniques for Static Pile Load Testing in the late 1980's and has constantly developed the equipment, systems and techniques used by the company today. The data-logging systems used are adapted and programmed in-house. Accuracy and reliability are assured and adequate back-up systems are incorporated to minimise the risk of data loss.

With over 150MN capacity in its own hydraulic jacking equipment, the company can tackle virtually any size of load test using stock equipment. The largest jacks owned have a capacity of 15MN and stroke of 300mm. All the company's large capacity jacks incorporate the load cells within the rams to keep the load system compact and stable to increase safety.

The PMC hydraulic pumping systems are controlled by the data-logger which automatically applies and maintains each load increment within fine limits. Higher levels of automation are available for special situations.

PMC's electronic load cells were developed in conjunction with the manufacturers and prototypes were thoroughly tested at the National Physical Laboratory to ensure that accuracy is maintained under the harshest of site conditions. Capacities of individual cells range from 200kN up to 15MN and all incorporate a spherical-seat platen.

The company has unrivalled experience in carrying out load tests in all modes (compression, tension and lateral) on vertical and raked piles on land and over water. PMC offers a full instrumentation service and regularly carries out load tests on piles incorporating cast-in-situ gauges of all types. Data from all instruments is logged simultaneously and presented as an integral report.
