Silage clamp and slurry store construction is the building of the concrete structures a livestock farm uses to make and keep silage and to hold slurry until it can be used on the land. Both are regulated, because silage effluent and slurry are among the most polluting materials on a farm if they escape.
That makes the groundwork underneath them critical: the excavation, the base, the falls and the effluent drainage all have to be right before a clamp is filled or a store takes its first slurry.
Luna Maintenance Ltd builds silage clamps and slurry stores across West Cornwall, as part of the agricultural groundworks we deliver for livestock and mixed farms.
The Silage and Slurry Work We Build
New silage clamps
Clamps with a concrete floor laid to fall, walls to contain and support the silage, and channels that carry effluent to collection. The wall system is agreed with you at the site visit to suit your clamp and your machinery.
Replacement clamp floors
Worn and pitted clamp floors broken out with the excavator breakers and relaid, so effluent runs where it should and the clamp can be cleaned out cleanly.
Effluent collection
The channels, drains and collection that the regulations require, keeping silage effluent contained and away from clean water and watercourses.
Slurry stores
Some farmers know it as a slurry lagoon. The structure we build is the slurry store, from the excavation and the base up, sized and sited with you to suit your herd and your system.
Aprons, yards and dirty water links
The concrete apron at the face of the clamp and the yard links that carry dirty water to the store, laid with our farm concrete yards work.
Bases for silage sheds
Concrete bases for covered silage storage and the buildings beside the clamp, with the frame erected through our agricultural buildings work.
Our Silage and Farm Concrete Work
Our farm concrete work includes silage-shed bases and building pads poured by our own team, alongside the clamps, stores and yards a working livestock farm relies on. Every job on this page was carried out by Ross and the team.

Build the structure.
The base is compacted and the concrete floor poured to its falls, with the walls or store built to the agreed design.
Cure, check and hand over.
The concrete is left to cure before it takes any load, the channels are checked, and we walk the finished work with you.
Why Farms Choose Luna Maintenance for Clamps and Stores
Clamps and stores are among the most tightly regulated structures on a farm. Under the Water Resources (Control of Pollution) (Silage, Slurry and Agricultural Fuel Oil) (England) Regulations 2010, a new or substantially altered silage clamp or slurry store must be built to the standards the regulations set, and the Environment Agency must be notified at least 14 days before it is first used. The reference standard for the design is BS 5502.
Built to the regulations. We plan every clamp and store round those requirements from the first site visit.
Groundworks specialists. Excavation, bases, falls and drainage are the core of what we do.
Accredited for the serious work. CHAS accredited and a Constructionline Gold member.
