We have a range of precast products that can be used to create silage clamp retaining walls. The maximum height of your clamp will depend upon the crop being used. Generally, we find that the most cost-effective heights are up to 3m, however, we can provide precast walls of 4m high, which can be beneficial for larger clamps and Anaerobic Digestion plants.
When designing agricultural retaining walls for silage clamps, it is important to consider the surcharge that will be applied to the walls when compacting. Traditionally a 10kN/m² surcharge capacity was adequate. For larger farm clamps and Anaerobic Digestion facilities, we have specifically designed retaining walls that can achieve up to 15kN/m² surcharge capacity, if you will be rolling the silage with larger machines.
Our precast retaining walls can be used with reinforced concrete floors, as well as asphalt, giving you the option of using both floor types. 90° corner units are also available for our silage clamp walls, enabling you to construct multiple clamps with ease.
Joints between the precast elements can be sealed, enabling these products to contain any liquid and leachate. Due to the aggressive nature of the liquid produced in silage clamps, we recommend SIKA TS Plus. This elastic sealant is resistant to liquid manure and is also suitable for sealing domestic sewage systems.
A common precast product used for constructing silage clamp walls is prestressed concrete panels. The horizontal concrete panels are available in a range of thicknesses and are quick and easy to install to the steel columns. Alternatively, the panels can be installed into cradles and concrete foundations to form vertical cantilever walls.
Prestressed concrete panels for silage clamps are available in three thickness when being used as a retaining wall and have a tongue and groove profile;
There are three standard heights in the concrete wall panels range, however, the panels beds can be altered to cast a panel of any height from 500mm:
The lengths of concrete panels are manufactured to suit specific wall dimensions, up to 6m (20ft). The length and thickness of the prestressed panels will depend on the retained height of the crops being stored and the size of the machine being used.
If you prefer not to have exposed steel columns in your clamp walls, then an independent retaining wall system, such as the bolt-down or cast-in retaining wall is an excellent alternative. The bolt down walls are available in heights up to 3.75m, the cast-in walls up to 4.3m high for the heavy-duty version.
Out AGRI range of high-quality precast retaining walls were designed for the needs of the Anaerobic Digestion and Biogas industries. The larger clamps required to keep up with energy production resulted in the need for larger, heavier plant required to successfully consolidate the crops.
The main USP of these units is the speed of installation. It is possible to install up to 100m of retaining wall in one day. Available in lengths of up to 5m, the vertical walls also reduce the time and cost of sealing the concrete joints.
AGRI retaining walls are available in a variety of heights from 1.39m to 4.22m and come in three profiles:
The different profiles can be used individually or combined to create vertical sidewalls and dividing walls for multiple clamps.
