Top 7 Manure Bunker Systems in the UK for 2026
Published on Wednesday, 25 February 2026
A solid manure bunker is a walled hard-standing store — usually precast concrete panels on a sealed base, occasionally galvanised steel — that holds stackable farmyard manure until it can be spread. The seven systems below come from UK and Irish precast manufacturers and are quoted per project rather than sold off the shelf, so panel height, bay width, base slab and drainage are agreed with the maker before ordering. In England three sets of rules bear on the job: the SSAFO regulations (the Water Resources (Control of Pollution) (Silage, Slurry and Agricultural Fuel Oil) (England) Regulations 2010), the Farming Rules for Water 2018, and, on holdings inside a Nitrate Vulnerable Zone, the Nitrate Pollution Prevention Regulations. Wales, Scotland and Northern Ireland run their own equivalents. Buyers usually weigh panel height and lateral load rating, whether leachate drains to a collection tank, freeze-thaw durability, cover options for odour and ammonia, and whether the bay size suits their loader and muck spreader.

Creagh Concrete Agricultural Bunker Wall System
Creagh Concrete's agricultural bunker wall system is positioned as a market leader for durability and site-ready precast units; its heavy-duty reinforced panels and tight tolerances reduce on-site labour and long-term maintenance costs compared with lighter or bespoke alternatives. For solid manure storage it stands out by lowering installation time and providing a robust, low-depreciation structure versus steel panels or less standardised precast offerings on this list.
Moore Concrete Precast Manure Bunker Walls
Moore Concrete's precast manure bunker walls focus on cost-effective modularity, offering standardised panel sizes that simplify expansion and replacement, which can be cheaper over time than welded steel or bespoke cast-in-place solutions. Compared with other products listed, Moore balances upfront capital cost and straightforward logistics for solid manure storage, making it an attractive choice when predictable budgeting and phased build-outs matter.
Buchan Concrete Silage and Muck Store Bunker
Buchan Concrete's silage and muck store bunker is notable for its agricultural-specific design details—such as high lateral strength and abrasion-resistant mixes—that prioritise longevity in corrosive and high-load environments. For solid manure storage it competes on technical robustness over standard precast panels and offers a better lifecycle return where chemical and loading conditions would rapidly degrade lesser systems.
O'Reilly Concrete Cantilever Agri-Bunker Walls
O'Reilly Concrete's cantilever agri-bunker walls deliver a structurally efficient approach that reduces foundation demands while maintaining high containment capacity, which can cut groundwork and civil costs compared to fully buried or heavier-wall systems. For solid manure storage this makes O'Reilly attractive where soil or site constraints favour reduced excavation and where the cantilever advantage outperforms flat-panel options in material usage and installation speed.
Shay Murtagh Precast Agricultural Bunker System
Shay Murtagh's precast agricultural bunker system is a market standout for production scale and quality control, offering consistent panel geometry and integrated lifting points that speed installation and reduce labour risk. Compared with bespoke or smaller manufacturers in this list for solid manure storage, Shay Murtagh can provide competitive lead times and standardised warranties that translate into financial predictability for larger projects.
Pearson Livestock Muck Store Walling
Pearson's livestock muck store walling is tailored to animal-housing and muck-handling workflows, with smooth finishes and robust joints that simplify cleaning and reduce contamination risk, delivering operational savings over time. Against other entries for solid manure storage, Pearson prioritises hygienic and maintenance benefits that make it technically preferable where frequent cleaning and biosecurity are cost drivers.
Wright Engineering Galvanised Steel Bunker Panels
Wright Engineering's galvanised steel bunker panels offer a lightweight, modular alternative that reduces delivery and handling costs and enables rapid erection compared with concrete systems; galvanisation provides good corrosion resistance for many farm environments. For solid manure storage, these steel panels can be the most financially appealing short-term option and the fastest to deploy, though they trade off some long-term abrasion resistance and mass compared with heavy precast concrete solutions on this list.
What the UK rules actually require
Manure storage in England sits under three sets of rules rather than one. The SSAFO regulations govern silage and slurry stores and require written notice to the Environment Agency before a store is built, substantially enlarged or reconstructed. The Farming Rules for Water 2018 require organic manure to be stored and applied so it does not cause diffuse pollution. Inside a Nitrate Vulnerable Zone the Nitrate Pollution Prevention Regulations add fixed storage periods and siting distances. A permanent walled bunker on a sealed base is the usual way to satisfy all three, because temporary field heaps carry much tighter siting limits.
Notify the Environment Agency at least 14 days before you build, substantially enlarge or reconstruct a silage or slurry store in England (SSAFO).
A temporary field heap in an NVZ must sit at least 10 metres from any surface water or land drain — 30 metres where the land slopes at 12 degrees or more — and at least 50 metres from a spring, well or borehole.
A field heap must be moved at least every 12 months and the same site cannot be reused for 2 years; a walled bunker on a sealed base avoids both constraints.
NVZ slurry storage capacity is 5 months (1 October to 1 March) for cattle, sheep, goats, deer and horses, and 6 months (1 October to 1 April) for pigs and poultry.
Wales, Scotland and Northern Ireland run their own schemes — Wales applies NVZ-style rules across the whole country — so check the rules for the country the yard is in, not England's.
Frequently Asked Questions
Which bunker wall system should I choose for muck retention?
Creagh Concrete Agricultural Bunker Wall System is a strong choice for long-term silage and muck retention because it uses precast reinforced concrete panels with interlocking joints and lifting points for secure alignment.
What exact joint design does Moore Concrete use?
Moore Concrete Precast Manure Bunker Walls use tongue-and-groove joints to minimise seepage, with reinforced sections designed to resist slurry corrosion and heavy lateral loads.
How does price compare between these bunker wall systems?
Precast bunker walls are quoted per project rather than sold at a fixed shelf price: manufacturers price by panel height and linear metre, and delivery, craneage and the base slab are normally costed separately. Galvanised steel panel systems usually sit below concrete on supply cost but have a shorter life in a muck or silage environment. Ask each supplier for a supply-only figure and an installed figure for the same bay size so the quotes are actually comparable.
Which option is best for corrosive, high-load environments?
Buchan Concrete Silage and Muck Store Bunker is designed for corrosive, high-load environments with heavy-duty panels built for high silo pressure and impact, plus sealed joints and smooth faces.
