Monitoring Prism for Dam and Reservoir Monitoring Malaysia
Monitoring Prism for Dam and Reservoir Monitoring Malaysia
Dams and reservoirs are among the most critical infrastructure assets in any country. Over time, factors such as water pressure, seasonal changes, foundation settlement, earthquakes, and structural ageing can cause gradual movement. To ensure long-term safety, engineers use Monitoring Prisms with Total Stations to continuously monitor structural displacement with high precision.
At MTM Precision Sdn Bhd, we supply professional Monitoring Prisms for dam and reservoir monitoring projects throughout Malaysia, helping engineers obtain accurate deformation data for safe and reliable infrastructure management.
Why Is Dam Monitoring Important?
Even a few millimetres of structural movement may indicate changes that require engineering attention.
Dam monitoring helps engineers detect:
Structural settlement
Horizontal displacement
Wall deformation
Crest movement
Foundation movement
Concrete expansion and contraction
Long-term structural behaviour
Regular monitoring supports preventive maintenance and reduces the risk of unexpected structural failures.
How Monitoring Prisms Work
Monitoring prisms are permanently installed at carefully selected locations on the dam structure.
Typical installation points include:
Dam crest
Spillway walls
Intake towers
Retaining structures
Concrete walls
Foundation monitoring points
A Total Station measures the prism coordinates periodically, allowing engineers to compare changes over time and identify any structural movement.
