Silage Clamp Retaining Walls
Build better silage clamps with strength, speed, & compliance you can rely on.
What Makes Our Agri Walls Different
Our Agri retaining walls are designed to meet the specific demands of silage clamp construction in AD & Biogas projects.
With proven performance under 15-tonne axle loads and a range of units to accommodate every clamp layout, they’re the go-to choice for contractors and designers who need structural integrity, quick installation, and SSAFO compliance in one complete system.
Choose from AGRI-L, AGRI-T or AGRI-U to build safer, stronger, and more efficient silage clamps – without compromise.
- Engineered for silage clamps in AD & Biogas projects
- Withstands axle loads of up to 15 tonnes.
- Quick to install – longer units (up to 5m) result in fewer joints to seal
- Bevelled tops protect clamp sheeting from tearing
- Chamfered joints make sealing and reduce wear from machinery
- No fixings – clean placement with positioning rods for alignment
- Standard stock range with short lead times
- Fully compatible with asphalt or concrete clamp floors
- Compliant with SSAFO and Environment Agency requirements

We searched long and hard for a product with a suitably hard surface and a very high standard of finish. Cheaper panels can develop twists and misalignments if the joints aren't sufficiently tight, but CBS retaining walls are top-quality for an AD silage clamp.
