Pile Testing:

Compression load test (up to 4000 tons)

Tension load test.

Dynamic load test.

Pile integrity test.

Ultrasonic test.

 A pile is a slender foundation element cast in the ground or driven into it. Since pile construction as well as the final
product are mostly invisible, engineers have often questioned their integrity, i.e. their compliance with project drawings and specifications. In fact, experience  has shown that in piles of all kinds flaws may occur. The purpose of integrity testing is to discover such flaws before they can cause any damage.


Historically, pile integrity was investigated by direct methods. These included external methods such as excavation around the pile and internal or intrusive methods, such as core-drilling . While excavation may be effective in exposing flaws in the outer part of the pile, it is usually limited to a depth of a few meters. Core drilling, on the other hand, can be carried out to a large depth provides full information, but only for a very small fraction of the pile volume.

Indirect methods, or imaging, were first developed in the early 1970s. These include three distinct methods:

Nuclear radiation, or gamma-gamma method
Short wave (ultrasonic) acoustic method
Long wave (sonic) acoustic method
