Urban Green Tramways

INTRODUCTION INTERTECH Plus and BERA proudly present a groundbreaking solution for greening urban tramways. Combining over 15 years of INTERTECH Plus’s expertise in comprehensive noise reduction for tram and railway systems with BERA’s commitment to environmentally sustainable solutions that conserve water for future generations, this partnership marks a new chapter in urban infrastructure innovation. Introducing BERA RailFix – Powered by INTERTECH Plus: An innovative approach to silent, green, and sustainable tramway integration.

In July 2024, the Joint Research Centre (JRC) of the European Union identified Urban Heat Islands (UHI) and urban overheating—resulting from prolonged periods of extreme temperatures—as a significant and growing effect of climate change. In urban environments, sealed surfaces such as roads and buildings absorb heat throughout the day and release it at night. This not only causes discomfort but also poses serious health risks, including dehydration, heatstroke, and worsened air quality due to trapped pollution. Multiple research studies and publications have confirmed that these health risks are...

What is BERA® RailFix BERA® RailFix is an innovative modular system designed to green urban tramways while delivering a wide range of environmental, structural, and operational benefits. • High-strength, driveable cellular modules with excellent water retention capacity • Integrated sound-reducing rubber elements • A low-maintenance green surface, planted with local succulents such as sedum These modules are installed between and alongside tram tracks, maximizing their ecological impact. All components are made from 96% recycled materials and are fully recyclable at the end of their lifespan....

ADDITIONAL NOISE & VIBRATION REDUCING OPTIONS In addition to the noise reduction achieved by BERA RailFix, there are optional methods to further reduce noise and/or vibration by these products: 1. Low Noise Barrier (LNB) in L or T configuration, reducing up to 6 dB(A) 2. Anti-vibration mats (CONIRAP) 3. Rail Noise Absorbers For more info, please check the following pages.

LNB - TYPE T The Inverted T-Type Low Noise Barrier (LNB-T) is composed of three prefabricated components that are assembled on-site to form an effective acoustic barrier. Its inverted T-shape provides a selfsupporting structure, eliminating the need for additional anchoring. The barrier is manufactured from 100% recycled rubber, encased in concrete base profiles for stability and topped with a stainless-steel cap for enhanced durability and a refined appearance. The LNB-T can be installed either as a stand-alone unit between tram or rail tracks, or alongside the tracks, depending on project requirements....

LNB - TYPE L The LNB-L is a robust, L-shaped low noise barrier constructed from solid concrete. Its track-facing side is covered with a corrugated rubber layer, specifically designed to enhance noise absorption and minimize sound reflection. The LNB-L is installed alongside the track, offering an effective and durable solution for reducing rail-related noise. For improved visual integration in urban environments, greenery or vegetation can be added to enhance the aesthetic appeal for nearby residents.

The comprehensive system range of CONIRAP anti-vibration mats helps to eliminate noise transmitted from train bogies on surface and underground tracks and thus contributes to improvement of the environment. They can be used under gravel or concrete beds or for specially adapted systems for installation on rails. Static stiffness Dynamic stiffness
