How does Holland Dredging Industries™ guarantee quality and traceability?

At Holland Dredging Industries™, quality assurance is fully integrated into our operations. Every order is accompanied by batch-specific material certificates and logged into our centrally managed, traceable documentation system. This ensures that all materials, processes, and machines used in production can be verified at any time—today or years into the future.

In consultation with our clients, we define which reference samples must be archived and for how long, providing an additional layer of security and accountability.

To validate performance and compliance, we collaborate with aerospace-certified and independent European laboratories. Through these partnerships, we can perform a full spectrum of mechanical and chemical analyses, including both destructive and non-destructive testing.

For clients requiring official certification, we supply EN 10204 3.1 certificates with each delivery. This ensures that the quality of the shipment is independently verified and guaranteed by a recognized testing institute.

Our system is designed for absolute transparency, reliability, and long-term traceability—so you can trust not only the materials you receive today, but also the documentation that supports them for the future.
