Percussion Drilling

Percussion drilling represent fundamental and widely-used drilling method in geotechnical and site investigation work, particularly for deep foundation project where understanding subsurface condition be critical to foundation design and construction success. Also known as cable percussion drilling or cable tool drilling, dis technique employ heavy percussion hammer wey dey suspend on steel cable to repeatedly strike and break through soil and rock layer, gradually advance borehole to significant depth. Method don remain preferred approach for foundation engineering and ground investigation due to simplicity, cost-effectiveness, and ability to produce disturbed soil and rock sample wey accurately represent subsurface stratigraphy across multiple layer and horizon.
