As key arteries in the UK’s strategic road network, the M40 and M42 corridors are undergoing critical upgrades to enhance long-term resilience, safety, and sustainability. Central to this transformation is the modernisation of surface water management — an area where BG-Graspointner’s FILCOTEN® channel drainage systems continue to set the benchmark.

Raising the Standard for Public Infrastructure

Highways and public assets demand drainage solutions that can withstand heavy traffic, unpredictable weather, and continuous operational pressure. For the M40/M42 upgrade, this meant specifying systems that deliver:

• Exceptional load performance for HGV and high-volume traffic
• Lightweight installation to reduce programme time and on-site risk
• Long-term durability with minimal maintenance requirements
• Sustainable material credentials aligned with public-sector carbon goals

BG-Graspointner’s FILCOTEN® HPC — a high-performance, fibre-reinforced mineral composite — provided the ideal balance of strength, sustainability, and ease of installation.
FILCOTEN®: Engineered for Highways and Civic Environments

With load capacities up to F900, FILCOTEN® ensures stability under extreme traffic conditions. Its lightweight construction supports faster installation and reduces manual handling risks — a major advantage on live carriageways and time-sensitive projects.

Supporting Public-Sector Sustainability Goals

As local authorities and national agencies intensify their focus on embodied carbon and lifecycle impact, FILCOTEN®’s environmental profile stands out. The material is:

• Reducing CO₂ emissions during production
• Fully recyclable at end of life
• Manufactured with optimised resource efficiency
• Designed for long service life, reducing replacement cycles

For public-sector procurement teams, this aligns directly with long-term value and sustainability commitments.

A Proven Solution for Civic & Public Projects

Beyond the M40/M42, BG-Graspointner systems are widely deployed across the civic landscape — from transport hubs and public squares to educational campuses and municipal developments. The M40/M42 upgrade reinforces a broader trend: public infrastructure is increasingly turning to high-performance, low-impact drainage systems that deliver reliability without compromise.
