Why rebuild a noise barrier if you can simply make it more effective?

Noise mitigation is a complex and costly issue for infrastructure operators. Road and rail traffic are increasing across many regions in Europe – and so is the pressure from communities, regulations, and environmental goals.

Over the past decades, significant investments have already been made. Noise barriers are in place in many areas – but often based on older standards, lower traffic volumes, or outdated planning assumptions.

The result: many of these walls are too low to meet today’s requirements.

Between doing nothing and starting from scratch – there is a third way

Demolishing and rebuilding existing walls is expensive and disruptive. There are several cases where a lot of money has been buried already. But doing nothing isn’t an option either.

That’s where PIN comes in. PIN is a lightweight retrofit element for raising the height of existing noise barriers – without replacing the structure. It has already been tested and measured in real-world settings along both roads and railways. The result: significant improvement in acoustic performance at minimal cost and minimal intervention.

When is retrofitting the smarter choice

Retrofitting makes sense when the existing barrier is still structurally intact but no longer meets acoustic requirements. In many cases a full replacement is either too expensive or not justifiable given the local context. Sometimes there is an urgent need to improve noise protection quickly and with minimal disruption especially near residential areas or sensitive infrastructure.

PIN offers a way to enhance the effectiveness of existing noise barriers without large scale construction
It allows infrastructure operators to respond to rising acoustic expectations in a practical efficient and sustainable way.

Rethink noise protection – build smarter, not bigger

Sometimes the smarter solution is not to build more, but to adapt what’s already there. If you want to learn about projects where this solution has been already applied, just get in touch and we will happy to share more details!
