Durable and Functional Solutions

The solutions from Gerhardt Christensen A/S are tailored to meet individual demands for functionality. Our engineers are very experienced in calculating and dimensioning projects to satisfy regulatory standards and requirements with regards to both strength, environment and durability under extreme conditions.

All solutions are thoroughly tested prior to final handover. Based on many years of experience facing numerous challenges in the areas of environment, clean water, and sewage, we are capable of solving any task.

To a great extend we act as advisors and partners during development of entirely new solutions, where experience and creativity are critical to a successful outcome.

We are proud to be used as a yardstick for quality. That reputation carries an obligation and we are prepared to do anything to keep it up.
