Sources of Microtremors in the natural environment
Benefits of Microtremor Surveying
From utilities to transport infrastructure, microtremor surveying is a versatile, quick and non-invasive tool for subsurface detection.

Capabilities
The Microtremor survey method can detect subsurface conditions and objects to a potential penetration depth of up to a few thousand metres.

Timely and Efficient
A single array data collection session takes 10 to 30 minutes, allowing for efficient deep soil investigations.


Microtremor Surveying
Underground structure toe foundations, utility pipe detection, box drain culverts can all be detected.

Minimal Regulatory Application
As a non-destructive investigative method, there will be zero potential damage to ground structures. No NCE is required.
Safety and Strong Anti-Interference
Microtremor surveying does not require explosives or sledgehammers, and is also immune to electromagnetic interference.
Other Methods to Detect Foundation: Magnetic Logging
From infrastructure verification to foundation investigation, magnetic logging is a versatile, quick and non-invasive tool for subsurface detection.

Capabilities
Detects anomalies in the earth’s natural magnetic field caused by buried ferromagnetic materials. Accurately determines steel cage depth, length, and reinforcement changes – to a maximum depth of 200 metres.
Accurate and Reliable
Produces a clear magnetic anomaly profile with distinctive signatures.




Magnetic Logging Surveying
Foundation toe levels, steel cage lengths, contiguous bored pile depths, buried metallic structures can be verified through access boreholes positioned closely.
