Pile Integrity Testing Service
Ever since our inception in the industry, our company is enlisted amongst leading service providers of PIT Testing. In order to execute and render this service, we have appointed team of qualified professionals and other supporting staff. This service is best suitable for Slender structural elements like driven concrete piles, structural columns, cast in place concrete piles, timber piles and concrete filled steel pipe piles. The PIT Testing that we provide is a cost effective way to test the continuity of concrete of pile. Apart from this, clients can avail this testing service from us in different specifications.
A smart blow but not necessarily a hard one, on the head of a pile generates a compressive sonic wave having a length of 2.0 m to 3.0m, traveling at a speed of 3500 to 4500 m/sec., along the pile shaft. It is reflected whenever there is any change of impedance on the way. Given a hypothetical case of smooth cylindrical pile of uniform cross section , density and soil friction around it, the wave will be reflected from the toe only and return as a tensile wave after travelling down and up along the entire length of the pile . An acceleration pick up attached to the top of the pile has been designed to send signals through the hardware to generate reflectogram of the wave time domain. With the linear and exponential amplification, filtering system in-built in the apparatus, it is possible to locate the depth of major changes in the impedance of the tested element. The nature of the reflectogram gives the length of the pile, sudden changes in cross section and discontinuity, if any.
It meets standards like ASTM-5882-07, IS 14893-2001
