Effective installation starts with the right tool
When you install a rat blocker from Nordisk Innovation, it should be easy – and it is with our specially developed tool.
Everything is designed to fit with Wolf-Garten telescopic poles and gives you precision and safety from initial installation to ongoing service.
Maximum rat protection – almost impossible to climb
Through many years of experience, close dialogue with sewer masters and a strong culture of innovation, we at Nordisk Innovation have developed a rat barrier that is close to being impenetrable to rats.
The graph illustrates how we have systematically raised the security level of our products. By combining multiple layers of protection – from the use of acid-resistant stainless steel, double damper, sharp teeth and an advanced locking system – we have created a barrier that rats find extremely difficult to climb.
Each element is based on practical experience from reality, where together with sewer masters we have optimized every detail to ensure maximum operational reliability and durability.
With our rat barrier you don’t just get a product – you get the result of years of innovation, testing and documented effectiveness.
Prevention rather than control – without the use of poison
Up to 90% of all rats originate from the sewer system, and they can cause serious damage to buildings, installations and health.
Our rat blocker is an effective, non-toxic solution that is installed directly in the well. It prevents rats from penetrating faulty sewers – and provides long-term, sustainable protection without the use of poisons or traps.

FAQ: Installation
FAQ: Service
If the rat blocker is installed correctly and then serviced regularly, it very rarely breaks. It usually only happens if the sewer is flushed without first removing the blocker.
If you have installed a barrier in a building housing many people (e.g., a school or hospital), we recommend a more frequent schedule with 3-4 service visits per year. The same applies to rat blockers installed immediately after a grease separator.
FAQ: Clogged sewer
The sewer specialist is also responsible for servicing the blocker. If the service agreement is not upheld, the sewer specialist is liable for the costs. However, if the sewer clogs due to foreign objects, it is the building owner who must cover the costs.
