About MAREX
An integrity specialist for iconic underwater structures, operating worldwide from Dubai.

MAREX is a specialist in underwater non-destructive testing (NDT), inspection, quality control and technical expertise for iconic underwater structures. Our references include some of the world's largest public aquariums and ambitious architectural and commercial pools, and we apply the same methods to marine and coastal infrastructure.
Our founder brought offshore inspection methods to public aquariums, at a time when they were treated as leisure pools rather than chemical plants. That discipline defines how we work today: structured methods, certified inspectors, documented evidence.
Global deployment
MAREX has operated in South America, the United States, Africa, Europe, Russia, Asia and the Middle East. Teams and equipment are mobilised from our headquarters in Dubai and our local offices in several countries.
