Adaptive Solutions
Remote Access Sampling
Over the years, TG&B has continually adapted to meet the changing needs of our clients, developing new platforms and techniques to tackle a wide range of sampling challenges.

How It Works
Process Snapshot
Step 1
Collection
A core tube is vibrated into the seabed or riverbed to capture an undisturbed sediment sample.
Step 2
Retrieval
The sealed sample is carefully lifted, capped, and secured for transport.
Step 3
Delivery
Samples are carefully packaged and delivered to certified analytical laboratories for testing and reporting.
