Frequently asked questions

published by the company
Where can I get the DOPA® linings or ADISA® coatings?

Our coating products and lining systems, including DOPA®, are available worldwide. Our many years of experience in customs and shipping means that we can offer hassle-free customer service and delivery.

Where can structural linings be applied?

They can be applied to above-ground tanks, underground tanks and concrete surfaces in contact with chemicals, water, food, etc.

What is the corrosion class of your coatings?

Our external coatings can protect your assets from C3 to C5, meaning we have solutions for even the harshest conditions.

Are ADISA® coatings suitable for modern fuels?

Many of our products are approved for use with aggressive biofuels such as ethanol. In particular, our EPOFLEX® range of coatings is highly compatible with aggressive storage liquids.

Do you offer application training?

We offer training to local technicians in the application of our certified coatings and structural lining technologies.

How does the DOPA® double wall lining work?

A vacuum interstitial space is created and monitored 24/7 by a vacuum leak detection system. It consists of a primary and a secondary containment.

What does In-situ / Ex-situ mean?

In situ/Ex situ: These terms refer to locations. An in-situ process or treatment is carried out on site, whereas an ex situ process or treatment is carried out off site.

What is Bioremediation?

This branch of biotechnology uses living organisms like microbes and bacteria to remove contaminants, pollutants, and toxins from soil, water, and other environments. It may be used to clean up contaminated groundwater or environmental problems such as oil spills.

What is Phytoremediation?

This specific remediation process uses plants to remove pollutants in the soil and the groundwater. In the case of soil, it is especially suitable for near-surface contamination because it treats the topsoil layer.

What is Geoengineering?

Developed in natural environments, this intentional activity aims to reduce or neutralise climate change. It includes a wide range of techniques, in situ and ex situ.
