Gramm Barrier Systems Ltd

Specialist Noise Barrier & Acoustic Fencing Solutions for Infrastructure and Development

GRAMM are specialist noise barrier and acoustic fencing designers, manufacturers and installers, with almost 30 years’ experience delivering high-performance, compliant and sustainable acoustic solutions across the UK.

We provide a fully integrated service, supporting projects from early contractor involvement (ECI) and feasibility, through detailed design, acoustic modelling and noise reporting, to full manufacture, supply and installation.

Our collaborative approach makes us a trusted partner for specifiers, landscape architects, designers, consultants and contractors working on complex infrastructure and development projects.

Markets & Sectors

GRAMM deliver noise mitigation solutions across a wide range of sectors, including:

• Highways and major infrastructure
• Rail
• Residential and mixed-use developments
• Industrial and commercial schemes
• Housebuilders and urban regeneration

Our systems are designed to meet the technical, environmental and aesthetic requirements typically demanded by planning authorities, highways authorities and design teams.

Innovative, Landscape-Led & Low-Carbon Noise Barrier Systems

GRAMM specialise in innovative noise barrier and acoustic fencing systems that combine:

• High acoustic performance
• Structural efficiency
• Visual integration
• Low embodied carbon

We offer a wide range of materials and finishes, enabling designers and specifiers to select solutions that align with landscape strategies, sustainability targets and planning conditions.

Available materials include:

• Timber
• Recycled rubber from ELT
• Recycled polymer
• Steel
• Concrete
• Living / green barriers

All systems are engineered to comply with relevant highways, rail and infrastructure standards, while supporting design flexibility and long-term durability.

PAS 2080 Carbon Management & Sustainable Design

GRAMM actively support PAS 2080 carbon management principles, embedding carbon reduction into every stage of the project lifecycle.

Through early design engagement and value engineering, we assist specifiers and designers in reducing whole-life carbon, material quantities and construction impacts.

Our approach includes:

• Low-carbon material selection
• Use of recycled and reused materials
• Optimised spans to reduce foundations and concrete volumes
• Long service life with minimal maintenance

This makes GRAMM particularly well aligned with projects targeting sustainable infrastructure, net carbon reduction strategies and planning-led environmental outcomes.

Noise Barrier Product Ranges

HATKO® Carbon-Neutral Noise Barriers

HATKO noise barriers are carbon neutral and manufactured using recycled car and truck tyres & repurposed wind turbine blade carbon fibre, offering a robust and sustainable acoustic solution.

Fully CE Marked for use on Highways schemes and compliant with LD119 for National Highways schemes.

They provide excellent durability and performance while significantly reducing embodied carbon, supporting PAS 2080-aligned projects.

ECOSoundBlok® Living Noise Barrier

ECOSoundBlok is a living noise barrier system and a space-efficient alternative to traditional earth bunds. Capable of achieving heights of up to 5 metres with a footprint of only 2 metres, it enables greater land efficiency, supporting higher unit yields and tighter site constraints.

This system is ideal for:

• Residential developments
• Urban highways
• Landscape-led schemes
• Projects requiring visual screening and biodiversity enhancement

NATURALSoundBlok® Timber Noise Barriers

NATURALSoundBlok delivers highways-compliant timber noise barriers, combining proven acoustic performance with a natural aesthetic. These systems are widely specified for highways and residential developments where visual impact is a key consideration.

METASoundBlok® Steel Noise Barriers

METASoundBlok steel barriers are fully compliant with highways requirements, offering long-term durability, impact resistance and design flexibility for demanding infrastructure environments.

POLYSoundBlok® Recycled Polymer Barriers

POLYSoundBlok noise barriers are manufactured from recycled polymer and can span up to 4 metres, reducing the number of posts and concrete foundations required. This results in lower embodied carbon, reduced installation time and cost efficiencies, while maintaining high acoustic performance.

SmogStop® Air Pollution & Noise Barrier

SmogStop is the world’s first approved air pollution barrier, combining effective noise reduction with air quality improvement. Using advanced aerodynamics and photocatalytic technology, SmogStop can remove up to 50% of traffic-related air pollution, making it ideal for urban highways and sensitive residential environments.

1km of SmogStop is the equivalent of removing 200,000 from that stretch per day!
