A local team, from assessment to records
Gotech Chemical Ltd was founded in Hong Kong in 1982. Our team includes water treatment specialists, technicians and engineers, providing treatment, maintenance, chemical supply and water sampling for Hong Kong buildings.
The 500+ client figure counts customers, including property managers responsible for multiple buildings; it is not a count of individual sites.
Monitoring and testing
Eleven hospitals use Gotech real-time monitoring (2026). Gotech provides sampling and coordinates analysis through an independent HOKLAS-accredited laboratory; the test scope is confirmed for each job.
Monitoring serviceA record you can use
A written quotation sets out the agreed scope. Service records and laboratory results help the building team follow findings and planned actions.
