How Monitel’s Real-Time Wall Monitoring Supports Risk Management in Industry

Structural movement is a significant risk factor in construction, mining and infrastructure projects, where even minor shifts can compromise safety and lead to costly failures. Walls play a critical role in retaining soil and supporting structures, meaning it is of significant importance to ensure their stability and effectiveness.

External forces such as ground settlement and water pressure can cause gradual movement and instability over time. To prevent this, Monitel provides real-time wall monitoring solutions using high-precision tilt sensors.

These sensors continuously track structural movement, detecting small angular shifts that may indicate potential failure risks. By monitoring wall displacement in real time, project managers and engineers can respond to movement before it leads to cracks, tilting or collapse.

This article details why wall monitoring is important and how we can assist you in implementing a tilt sensor system. If you would prefer to speak directly with a member of our team, you can contact Monitel at admin@monitel.com.au or on (08) 6219 8284.

Why Monitor Wall Movement in Real-Time?

Amongst other factors, wall movement can be a consequence of:

• Ground settlement
• Excavation
• Water pressure
• Structural loads
• Seismic activity

Left undetected, even the smallest shift in alignment can escalate into cracks, tilting or even collapse.

Western Australian regulations mandate wall monitoring for large infrastructure and mining projects. The Mines Safety and Inspection Regulations 1995 requires analyses of pit wall stability and appropriate wall monitoring methods to assess long-term stability.

Additionally, the Work Health and Safety (Mines) Regulations 2022 requires mine operators to ensure safe conditions for workers. Monitoring wall stability will prevent ground failures and other hazards, ensuring compliance with those regulations.

Real-time wall monitoring provides continuous tracking of structural movement, helping identify risks early and prove your compliance. This is particularly important in:

• Mining and Excavation Sites: Ensuring retaining walls and underground tunnel supports remain stable under dynamic loading conditions.
• Construction Projects: Monitoring newly built or temporary walls for movement during excavation and foundation work.
• Infrastructure and Transportation: Tracking movement in tunnel linings, bridge abutments and retaining walls along roads and railways.
• Industrial Facilities: Detecting shifts in load-bearing walls that could impact operational safety.

How Tilt Sensors Enable Precise Wall Monitoring

Monitel deploys a range of tilt sensors to provide accurate, real-time data on wall movement. Two of the primary tilt sensors we use are:

In-Place Inclinometers (IPI)

The IPI is a high-precision sensor designed for continuous, automated monitoring of lateral wall movement. Installed within inclinometer casing, IPIs detect subtle angular changes and feature:

• Real-time monitoring of wall tilting and lateral displacement.
• Modular design allowing for multiple sensors to be installed at various depths.
• Integration with data loggers for remote monitoring and automated alerts.

These sensors are particularly useful for deep excavation sites, retention walls and tunnel linings, where movement can compromise safety if not detected early.

Inclinometer Spiral Sensor

Monitel utilises the Inclinometer Spiral sensor for tunnels and retaining structures. It measures twisting and misalignment within inclinometer casings, ensuring that data collected by IPI sensors is accurate and reliable. Its benefits include:

• Detects casing spirals that could affect measurement precision.
• Ensures inclinometer alignment for long-term monitoring accuracy.
• Supports infrastructure projects requiring high-precision wall stability assessments.

We also stock multiple varieties of tilt sensor casing, allowing you to choose an option suitable for your site-specific needs:

XC Inclinometer Casing

The XC Casing is a durable, precision-engineered casing designed for use in installations that monitor wall movement, ground stability and structural shifts. Constructed from high-strength ABS plastic, it is resistant to environmental degradation and performs reliably long-term.

The integral keyways within the casing guide inclinometer probes, ensuring accurate and repeatable readings of lateral displacement.

Its features include:

• High-impact ABS plastic construction for long-term durability.
• Precisely machined keyways to maintain sensor alignment for accurate readings.
• Secure couplings for a tight fit, minimising deformation and data inconsistencies.
• Compatibility with all standard inclinometer probes, making it a versatile solution for geotechnical monitoring.

QJ Inclinometer Casing

The QJ Casing is designed to deliver high-precision inclinometer readings in geotechnical and structural monitoring applications. Made from rigid ABS plastic or aluminium, it provides exceptional stability, reducing measurement errors caused by deformation.

The self-aligning joints ensure that casing sections remain perfectly connected, maintaining accurate keyway alignment.

Key benefits of the QJ Inclinometer Casing include:

• Rigid construction minimising bending and deformation for high-accuracy monitoring.
• Self-aligning joints for easy installation and consistent keyway positioning.
• Options for ABS plastic or aluminum, catering to different project requirements.
• Designed for compatibility with standard inclinometer probes, ensuring seamless integration into existing monitoring setups.

Monitel’s Approach to Real-Time Wall Monitoring

Our technology and product agnostic approach ensures that the most effective and cost-efficient sensors are used on each project. We do not design our monitoring solutions around a company allegiance, but rather a commitment to creating the best system for your site.

Using advanced tilt sensors, automated monitoring and cloud-based reporting, we are able to deliver reliable wall stability assessments that support all aspects of operational safety and efficiency.

Monitel’s automated data acquisition systems provide real-time alerts and continuous tracking, giving you the ability to respond to potential risks before they escalate into major structural failures.

Our wall monitoring service is designed to suit everything form retention walls to capping beams and can be deployed on any site, whether it be construction or mining.
