NDT Services can provide both compression and tension pile lead testing using a specifically designed system in accordance with the current I.C.E specification. We provide an efficient, reliable and flexible service, which can be adapted to cater for most load testing requirements.

Static load tests are carried out in order to assess the performance of a test pile when subjected to a predetermined load. Pile settlement can be determined at the working load and at multiples of the working load.

Also the ultimate bearing capacity of the test pile can be calculated. Static testing falls into 3 main categories:

1.Maintained Load Test

The load is increased in stages and held for a specific time. At 100% DVL the load is released and a second cycle up to 100% DVL + 50% SWL applied. Maximum settlement and residual settlement are calculated accordingly. Pile displacement is monitored in accordance with ICE requirements. A selection of reaction beams provide the capability to carry out testing using a variety of anchor pile systems.

2. Tension Test

Pile performance is monitored when subjected to a tensile load. Loading schedules are similar to the above. A hollow hydraulic cylinder is positioned over the test pile and reacts against a suitable reaction beam. Pile displacement is monitored in accordance with ICE requirements.

3. Constant Rate Of Penetration Test (CRP)

Carried out when the ultimate bearing capacity of the test pile is required. The rate of penetration is kept constant with increments in the load applied.

Reporting

For all tests a full report is dispatched to the client upon collation of all data, with initial preliminary findings issued immediately. Reports contain tabulated data along with graphic representations of load v’s settlement, load and settlement v’s time and displacement (individual transducer) v’s time. Additional representation can be provided upon request.
