Despite advances in design methodologies and piling techniques at site, difficulties and uncertainties still exists for design of piles in coralline deposits and weak carbonate rocks. Such deposits are known to be heterogenous in nature, and occupy major stretches of earth, where piling experiences are probably very scanty. Such deposits are associated with low unit weights and usually consist of weakly cemented calcareous and carbonate soils interbedded with coral rocks containing cavities which are completely void or filled with coral debris. Many of the studies indicate that conventional parametric relationships applicable for silica sand and rocks of Igneous, Sedimentary and Metamorphic origin, are not applicable to coralline sediments and rock formations. Hence, the titled paper is proposed to provide brief appraisal on the technical concerns in coralline sediments and carbonate rocks and compares the performance of load tests with predicted unit side shear and end bearing resistances.
