Instrumentation and Monitoring Services

Every ground investigation has different monitoring needs. Groundwater pressure and flow, ground movement, settlement and slope instability can all affect the performance of engineering structures and the final cost of construction. In addition, we can also investigate the concentration and emission rates of ground gases or monitor the movement of contaminants through the ground.

Used either pre- or post- construction or during the building phase to confirm or other wise appraise the ground model we provide a wide and varied range of techniques.

Groundwater Investigation

Standpipe piezometers, vibrating wire/pneumatic/hydraulic piezometers and multilevel monitoring systems such as Waterloo and Westbay assist in the determination of ground water regimes and provide the geotechnical parameters needed for efficient and effective engineering design relating to:

• Slope stability/instability
• Settlement control
• Contamination pathways
• Seepage/soakage rates
• Porewater pressure
• Tidal effects

Gas Concentration and Flow

Where gas originates from natural ground such as coal measures, made ground or landfill Soil Mechanics can install and project manage instrumentation to monitor the levels, emission and flow rates of gases such as methane, carbon monoxide, hydrogen sulphide, carbon dioxide and oxygen.

Ground Movement

For the accurate measurement of horizontal and vertical ground movements ESG has extensive experience of installing monitoring instrumentation such as inclinometers and extensometers in:

• Embankments
• Land slip areas to shear planes
• Tunnels
• Excavation
• Shafts
• Piles and retaining walls
• Foundations
