Silocover on concrete element silo


Wiefferink’s silo cover is a unique proposition in our market. It has a very long lifespan due to the high-grade materials and innovative production technology used when manufactured. Meaning it is an extremely durable cover for your silo.

In order to contain the emission of hazardous materials, there is a duty to cover stored manure in many European countries. The Silocover is ideal for covering silos. With one or more inspection openings, the mixers often present in the tank can also be maintained. Moreover, rainwater is kept out of a covered silo, so there is no unnecessary volume increase.

In accordance with environmental directives

Every EU member state is currently adjusting its regulations regarding CO2 emissions, making the use of a cover largely necessary or required. This has already been implemented in the Netherlands, Denmark, Belgium, Italy and Eastern European countries, among others.

Our Silocovers satisfy both environmental legislation and construction-related directives.

Absorbs external forces

The Silocover is manufactured from heavy polyester fabric with a synthetic coating on both sides. As a result, it can withstand manure and other aggressive substances and protects against many years of extreme weather conditions. The Silocover is equipped with an unique system of edge pipes and tension sets, which transfer the forces from the cone to the silo circumference. It is also possible to adjust the tension later. An inspection opening provides access to the silo for maintenance. The Silocover is available in a gas-tight and a non-gas-tight version.

KOMO certified

Odour nuisance and the emission of hazardous substances are minimised by the Silocover. The Wiefferink Silocover has a KOMO certificate and satisfies all statutory requirements.

Installation of the Silocover

The Silocover is delivered ready-to-use. 
If desired, assembled on site by our own assembly team (s). Wiefferink has several own specially trained assembly teams. The success of your project is made possible by the extensive experience of our assembly teams gained during very diverse projects with renowned clients around the world. All our engineers are internally trained and VCA certified. For every silo, the roof construction is calculated based on wind and snowfall values for your location.

Maintenance and lifespan

The Silocover requires very little maintenance; after a large snowfall
the snow must be removed, and the Silocover must be kept at the right tension.
