Green Gravity Walls’ ECO-MSE flood defence systems provide a modern, environmentally friendly alternative to traditional flood barriers and erosion control methods. Approved by the Environment Agency and trusted by Network Rail and major infrastructure partners, our ECO-MSE bags are engineered for use across rivers, canals, lochs, flood banks, and coastal waterways.
Constructed from 140 GSM non-woven geotextile, the bags are non-toxic, UV- and chemical-resistant, and designed for a 100+ year lifespan. Once vegetated, they become fully carbon-neutral while supporting biodiversity and enhancing Biodiversity Net Gain (BNG) outcomes.
Non-biodegradable yet safe for ecosystems, allowing natural vegetation growth and biodiversity.
Engineered to allow water to pass through, reducing hydrostatic pressure, preventing waterlogging, and maintaining natural drainage.
Can be filled with soil for vegetated finishes or granular material for rapid drainage and structural reinforcement.
100+ year durability with a 75-year warranty, ensuring long-term flood defence and erosion control.
Lightweight, modular design allows rapid installation without specialist machinery – ideal for both emergency and planned works.
Suitable for confined, hard-to-reach, or restricted-access areas where heavy plant cannot be used.
Our ECO-MSE systems are designed to provide robust, flexible solutions across a wide range of civil engineering and environmental projects:
Stabilises riverbanks, canals, and lochs against erosion and scouring.
Repairs bank slippages and prevents future collapses.
Creates natural vegetated barriers that blend into the landscape.
Permanent and temporary culverts and headwalls.
Bridge crossings in challenging locations.
Ditch lining to prevent erosion and ensure long-term water flow stability.
Flood bank creation to contain rising water levels.
Cofferdams for temporary diversion or protection during construction.
Emergency response solutions where rapid installation is required.
Creates stable embankments and naturalised flood defences.
Once seeded or hydroseeded, walls develop into living ecosystems that improve BNG scores and provide habitats for pollinators, insects, and wildlife.
✅ Environment Agency-approved for use near rivers, waterways, and sensitive ecological sites.
✅ Carbon-conscious alternative to concrete – dramatically reduces embedded carbon.
✅ Cost-effective – lower material and labour input compared to conventional systems.
✅ Biodiversity Net Gain compliant – supports environmental policy and sustainability targets.
✅ Proven in UK infrastructure – already in use across railway embankments, river defences, and flood management schemes.
Unlike many suppliers, we don’t just manufacture – we offer design, supply, and installation of ECO-MSE systems through our RISQS-approved partners, ensuring compliance with rail and civil engineering standards.
With experience delivering flood defence projects for local authorities, waterway managers, and national infrastructure providers, we combine technical expertise with sustainability leadership, helping clients achieve resilient, cost-effective, and eco-friendly outcomes.
Green Gravity Walls is committed to providing sustainable flood protection that stands the test of time. Whether you’re planning a riverbank reinforcement, a flood bank construction, or a temporary cofferdam, our ECO-MSE systems deliver durability, flexibility, and environmental value.
