A calculation note is available for each standard element. This can be requested free of charge. For each retaining wall the soil used to fill the side of the base must always be taken into account and have an equivalent mass of 1,800 kg/m³, in combination with a load of 1,000 kg/m² or extra stacking soil with an equal mass of 1,800 kg/m³ under a maximum talus of 30%. A calculation note can always be produced for heavier loads.
For the agri walls the material used to fill the side of the base must always be taken into account and have an equivalent maximum weight of 1,000 kg/m³. The maximum angle of repose is 30%. The maximum axle load above the repose angle is 15 tonnes for a vehicle with a wheel width of 1 metre, taking our instructions into account. When storing maize our walls are calculated for maize that is chopped to 6-8 mm with a dry matter content of at least 33%. In conditions where the concrete walls are exposed to chemical agression, extra protective measures are to be taken. One of the best measures is an Epoxy resin coating, combined with a plastic covering system. The calculation notes are compiled according to NEN 6702 and NEN 6720. The buyer declares to have been adequately informed about the properties of and possible applications for the goods sold. The buyer agrees to only use the goods for their intended purpose. He/she bears full responsibility for exceeding the recommended stacking heights and the recommended loads.
The agri U-type walls must always be filled with soil before driving towards the adjacent silo.
Our concrete complies with the strictest norms for European concrete standards NBN EN 206-1:2001 related to resistance against aggressive chemical attack. In certain environments an attack on the concrete elements cannot be ruled out entirely. To optimise the concrete’s sustainability and to reduce the risk of attack to an absolute minimum it is strictly recommended that our concrete elements are combined with silo varnish, coatings, epoxy or a silo lining. This preventive measure particularly applies to biogas installations.
