DATUMS
Satellite ground movement monitoring · Malaysia & Singapore
The ground moves. Most of the time, nobody is measuring it.
Datums uses radar satellite data to measure how much the ground beneath a building has moved — to the millimetre, going back to 2015. Klang Valley coverage is in development.
What we measure
SETTLEMENT
Ground consolidating under load. Common on former mining land, reclaimed ground, soft clay and peat. Slow, steady, and the main cause of structural damage to low-rise buildings.
DIFFERENTIAL MOVEMENT
One part of a building sinking faster than another. This is what cracks walls — not uniform settlement.
HISTORY
Radar archives go back to 2015. We can show how a building has moved over the past decade, even though nobody was watching at the time.
What this is not
Datums measures surface movement. It is not a structural assessment, and it does not replace ground investigation or a site inspection by a registered professional engineer.
We cannot predict sinkholes. Slow surface sag sometimes precedes a collapse and we will flag it where we see it, but many voids give no surface warning at all. Anyone who tells you otherwise is selling something.
