Is Code pile integrity test?
This is a system of assessing the integrity of piles by the use of low stress wave imparted to the pile shaft and is also known as Sonic Integrity or Sonic Echo Test. A small metal/hard rubber hammer is used to produce a light tap on top of the pile.
What is the pile load test?
Static pile load testing is one of the most common methods for testing the actual in-situ capacity of a pile. The test program involves the direct measurement of pile head displacement in response to a physically applied load. Piles can be tested for compression, tension or lateral loads. …
What is a pile load test?

How long does an ASTM load test take?
This kind of test is the ASTM standard procedure and the most common test, especially in large projects. A typical test lasts between 1.5 to 3 days. Quick Maintained Load Test (QML) In this procedure, 15% of the design load is added at a time and held for 5minutes.
How long should a load be maintained on a pile top?
Each load shall be maintained till the rate of displacement of the pile top is either 0.1 mm in the first 30 minutes or 0.2 mm in the first one hour or 2 hours whichever occurs first. The next increment in the load shall be applied on achieving the aforesaid criterion. The test load shall be maintained for 24 hours.
