ENGINEERING SITE INVESTIGATION

• Depth of bedrock
• Delineation of subsurface strata and weak zones (e.g. fractures, fault)
• Mapping of limestone bedrock topography
• Detection of cavities in limestone & sinkhole investigation
• Development of hot spring sites
• Mapping of underground tunnel
• Research on detection of granite boulders
