• Review site conditions, soil profile, and hydrogeology

• Drill boreholes at designated locations for piezometer installation

• Install piezometer with proper filter zones for groundwater measurement

• Seal borehole annulus with bentonite or grout for accurate readings

• Install data loggers for continuous monitoring

• Take initial baseline readings after installation

• Conduct periodic measurements or continuous monitoring

• Record groundwater levels and pore pressure variations

• Analyze trends for seasonal or construction-induced changes

• Compare readings with design or safety thresholds

• Provide early warning for slope instability or foundation issues

• Prepare monitoring report with recommendations

Piezometers are critical for monitoring groundwater pressure and fluctuations in soil or rock, which directly impact slope stability, excavation safety, and foundation performance. In Sri Lanka, where high water tables or heavy rainfall can affect construction, piezometer data is essential for safe geotechnical design.

The sensors provide continuous or periodic readings of pore pressure and water levels, enabling engineers to detect rapid changes that could trigger slope failures or foundation settlement. Data is analyzed against threshold limits to provide early warnings and proactive mitigation strategies.

Reports include groundwater trends, potential risks, and recommendations for construction adjustments, dewatering, or slope reinforcement. Piezometer monitoring ensures project safety, regulatory compliance, and risk reduction.
