Green Gravity Walls Delivers BNG-Boosting Infrastructure on Live Rail Site

Green Gravity Walls recently partnered with Network Rail to showcase the practical application of its ECO-MSE bag system at Mallard House — delivering a live, hands-on demonstration of how vegetated retaining structures can support both infrastructure resilience and ecological enhancement.
The demonstration focused on stabilisation around drainage zones, ballast retention for point protection, and the integration of soil-filled ECO-MSE bags with native vegetation. Using a combination of aggregate- and soil-filled bags, the installation was designed to highlight the system’s versatility across temporary works and permanent rail-side applications.
To accelerate vegetation establishment and promote long-term ecological function, Green Gravity Walls also delivered on-site hydroseeding, using a custom seed mix formulated to support pollinators and native grasses. This not only enhanced the visual appearance of the structure but also contributed to Biodiversity Net Gain (BNG) targets, aligning with the industry's growing focus on environmental compliance.
As an approved supplier to Network Rail, Green Gravity Walls continues to provide technical training and support to contractors and clients, helping them to integrate sustainable, low-carbon solutions into essential infrastructure. The Mallard House demonstration reinforced the benefits of modular, green engineering for use on embankments, culverts, drainage stabilisation, and beyond — offering a powerful alternative to traditional concrete or steel systems.
