These techniques are coupled with the engineering surface and subsurface remediation techniques and performed across three selected construction sites for housing complexprojects located in north and south of Ipoh city (Kinta valley) Perak state, Peninsular Malaysia. The civil and geo environmentalengineers in Perak state facing numerous and frequent problems in constructing the structures that situated over marbleized limestone karst regions, due to various class of karstic solution features such as sinkholes, caves, karstic voids or cavities, channel pipes, depressions, conduits, internal drainages system, solution-widened joints, intensely fractured zones and faults which directly exerts a negative impact on the use of the land for construction and the design of shallow foundation structure projects.
