Slope monitoring & instrumentation in Malaysia.
Piezometers, inclinometers, surface markers, crackmeters, and remote sensing for hillside developments, infrastructure corridors, and post-remediation verification. Manual or telemetry-equipped automated reading. CIDB G7. ISO 9001:2015. Coordinated with the appointed geotechnical consultant on monitoring plans.
Three signals from every slope.
Groundwater (piezometers)
Pore water pressure rise often precedes failure. Standpipe or vibrating-wire piezometers logged manually or via datalogger with telemetry.
Subsurface movement (inclinometers)
Detect deep-seated slip surfaces and confirm depth of moving mass. Manual readings monthly, more frequently after rainfall events.
Surface displacement (markers + crackmeters)
Surface survey markers, crackmeters across visible cracks, drone photogrammetry for slope-scale surface change.
Remote sensing
Drone surveys for inaccessible faces. Reflectorless total-station for repeat surveys. Increasing use of InSAR for large-area monitoring.
Pre-, during-, post-.
Pre-remediation diagnosis
Confirm the failure mechanism before designing remediation. Saves false starts and over-engineering.
During-construction control
Verify nails, drains, and walls behave as designed during installation. Triggers stop-work if movement exceeds thresholds.
Post-completion verification
Confirm the remediation is working. Piezometers verify drains. Inclinometers confirm no continuing movement.

What we install and why.
Inclinometer (SAA / probe)
Detects sub-surface lateral movement. Identifies depth and rate of any active slip surface. Borehole-installed to bedrock or below the failure zone. Read manually or via Shape Accel Array (SAA) for continuous data.
Vibrating-wire piezometer
Pore water pressure at depth. Critical for diagnosing whether groundwater is the failure driver. Multi-level installations show the piezometric profile through the slope.
Survey prism / total station
Surface 3D displacement. Reflective prisms surveyed by a remote robotic total station every 1-6 hours. Sub-mm precision over 100-300m baselines.
GNSS / GPS monument
Continuous high-accuracy positioning. Independent of line-of-sight. RTK or PPK processing achieves 5-10mm horizontal precision, useful for long-term trend monitoring on remote slopes.
Crackmeter / extensometer
Spans visible cracks in slope face, retaining wall, or shotcrete. Detects opening rate. Vibrating-wire or LVDT, logged continuously.
Tilt sensor / MEMS array
Surface rotation of retaining structures, gabion walls, MSE walls. Compact, battery-powered, wireless. Used where civil intrusion is constrained.
From the slope to your inbox.
Field logger
Solar-powered datalogger at the slope, logging all sensors at 5-15 min intervals. Cellular or LoRa uplink to cloud.
Cloud platform
Real-time ingestion. Time-series plots. Threshold-based alerts (yellow / orange / red). Web dashboard for the consultant + asset owner.
Alarm protocol
Automated SMS/email at threshold breach. Documented escalation procedure: who is informed at each level, what action is triggered.
Periodic reporting
Monthly engineering review of trend, anomalies, recommendation. Annual review of threshold relevance.
