Acoustic Barrier at Heathrow Airport
Precision installation for a secure, high-performance airside infrastructure project
Delivering critical infrastructure in a challenging airside environment
When Heathrow Airport needed a robust acoustic barrier to reduce noise pollution and improve operational efficiency, the installation had to meet strict engineering, security and logistical requirements. Working airside added an extra layer of complexity, with timed access, security protocols and minimal windows for construction activity.
The project involved installing a large acoustic barrier system designed to protect nearby areas from aircraft noise while supporting key airport operations. With sections of the wall set at an angle and connecting into vertical side walls, panel alignment had to be extremely accurate. This required detailed planning, strict sequencing, and coordinated access to ensure the installation stayed on schedule.
Our team worked closely with airport contractors to meet each security requirement, coordinate vehicle movements, and ensure that all lifting and installation activities could take place safely within the allocated airside access periods.
Project Overview
- Client – Heathrow Airport
- Location – London
- Sector – Aviation / Infrastructure
- Services Provided – Design, supply & installation
- Project – Heathrow acoustic and blast wall installation
- Products Supplied – Prestressed concrete panels
- Installation Duration – 2 weeks
Project Background
Heathrow is one of the busiest airports in the world, and any construction project within an airside environment requires exceptional control and coordination. Security checks, timed escorting, and strict movement protocols required precise planning before a single panel could be lifted.
The barrier itself required a structural system capable of managing noise, thermal control, and impact resistance. With an angled back wall connecting to vertical side walls, precise positioning was essential. Each panel needed to be installed and secured without deviation to ensure long-term performance.
Our Solution
Why Prestressed Concrete Panels
We supplied 210 prestressed concrete panels, each measuring 3.6m by 1m by 150mm, forming a structure 14m high with a plan size of 90 m by 70m. The panels were lifted into place and mounted onto a steel frame system using bolts and cleats at the rear.
All horizontal and vertical joints were sealed to form a complete acoustic and heat-resistant barrier, ensuring the system met both performance and safety standards.
Key benefits for this project included:
- Precise alignment – essential for angled-to-vertical wall connections
- Fast installation – panels tracked, lifted and secured within a tight programme
- High structural performance – robust acoustic and thermal protection
- Airside-safe process – coordinated access and controlled vehicle movement
The Results
Despite the strict airside protocols and technical complexity of the installation, the barrier was completed within the planned programme. The finished structure provides long-term noise reduction, enhanced thermal performance, and a secure, durable solution for one of the most demanding operational environments in UK aviation.
The project was delivered safely, efficiently, and to Heathrow’s strict standards, enabling ongoing airport operations with minimal disruption.
