INTRODUCTION

HEMCO Crosshole Sonic Logging (CSL) is an accurate cost effective, and non destructive means of investigating the integrity of concrete in drilled shaft foundations. These guidelines are intended enhance the quality of data acquired in CSL surveys by providing contractors with information on the preparation of shafts for CSL and the methods used to acquire CSL data.

CONCEPT OF CROSSHOLE SONIC LOGGING

The Sonic Integrity Logging Sometimes called Ultrasonic Test, Sonic Test, Sonic Logging etc. This test is performed to check integrity of concrete, locate defects and evaluate effectiveness of repair works on bored piles, caissons, barrettes and diaphragm walls and other concrete structures.

MAIN OBJECTIVE OF TESTING

When cast-in-situ piles are constructed, the following defects may occur, hence the main objectives in the testing is to provide the clients/consultants information about:
a)honey combing due to inadequate vibration.
b)segregation due to over vibration and improper concrete placement methods.
c)washout of cement due to groundwater flow.
d)cracks in pile shaft due to shrinkage.
e)Inclusion of foreign material causing contamination of the concrete.
f)necking of the pile due to collapse of sidewalls during withdrawal of the temporary casings.
This method on integrity testing requires prior pile preparation in that pipes need to be installed together with the steel reinforcement bars. There is no limit in the depth where the pile profile can be logged.
