Predict road collapse before it happens.

SinkAlert fuses satellite InSAR, road imagery, weather and citizen reports into a single AI risk engine — so agencies inspect the right place first, not after the road caves in.

Built on free & open Thai data — Sentinel-1, DMR, TMD, OpenStreetMap.

The problem

Underground risk is discovered too late

Road collapse can't be judged from the surface alone. Voids form silently under soft Bangkok clay — and today, inspection usually starts only after visible damage.

Hidden voids

Underground cavities are hard to detect and early warning is limited. By the time cracks appear, failure may be imminent.

Reactive inspection

Agencies inspect after collapse, not before. With thousands of km of road, they need to know where to look first.

Costly disruption

Emergency repairs shut roads and utilities, hurting businesses and communities — at many times the cost of prevention.

The solution

Five data sources, one risk score

SinkAlert's AI risk engine turns raw signals into an actionable priority — inspect the right place first, and use engineering budgets efficiently.
