Static load testing is used to provide a direct measurement of pile displacement in response to a physically applied test load and is considered to be the bench-mark of pile performance which is suitable for all pile types. Load testing a pile to failure identifies the maximum operating capacity of a pile and also provides valuable information to design engineers. It is recommended for load tests carried out prior to the foundation design, as the outcome of the tests are critical in verifying foundation design parameters and formulating remedial actions if needed. Testing on production piles is used to prove that the pile will perform satisfactorily at the design load plus an overload, to demonstrate that a building or structure will be adequately supported and that there is sufficient reserve capacity.

Test Procedure:

The test pile is subjected to loading using a hydraulic jack, and Strain stall designed and manufactured high capacity load cells are used to measure the load. Direct measurements of pile displacement under the applied weight are logged and the test results presented in a graphical format that shows loading versus pile head displacement.

Loading System:

The loading system of this test can be divided into several types as follows:

• Sand Bags.
• Kentledge Blocks.
• Reaction System (Reaction Piles / Ground Anchors).

These systems depend on the field conditions, loading value and other factors that dominate which type to choose. As a professional firm we have performed all these types of loading systems, and here are some photos as example:
