Bunker silo shelter 10 x 12 m PLUS arch roof

The PVC cover is stronger than PE (polyethylene/HDPE) and is therefore more resistant to weather conditions. PVC also has a longer lifespan.

For long-term projects, we therefore often see customers choosing PVC. This material is more durable, better suited for intensive use and remains in good condition for longer during long-term outdoor use.

We offer a declining warranty of 10 years on PVC. The declining warranty for PE is 3 years.

We explain the differences between the two covers in a short video.

Yes, our shelters are designed to withstand high wind and snow loads. Depending on the model, the maximum snow load ranges between 0.2 and 0.5 kN/m², and the maximum wind load between 0.3 and 0.665 kN/m².

Our shelters comply with the European standard EN13782, meaning they are calculated for combined wind and snow loads for added safety. In the product specifications, you will find the exact maximum values as defined in the official structural calculations. We explain this in detail in this blog.

Yes, please note: PVC cover is more fire-resistant than PE cover. In terms of fire safety, PVC clearly has the advantage. Although it is unlikely that both PE and PVC will catch fire, for example when using a grinder, PE will continue to burn once it has ignited. PVC, on the other hand, is flame-retardant and self-extinguishing, which provides additional safety.

The European standard EN13782 sets requirements for the design and construction of temporary structures, such as container shelters. This standard ensures that the shelter is safe and stable, even under changing weather conditions. It includes material specifications, calculations for wind and snow loads, stability checks and the strength of connections.

Our products are designed and tested according to this standard. This means you are assured of a safe and reliable shelter that complies with European regulations.

Yes, the structural calculations of the products can be found in the buildbook. This book contains all technical details and calculations required for the safety and stability of the shelters. You can request the buildbook free of charge, both online and in physical form.

The frame is made from S355 structural steel. This European steel grade is commonly used for load-bearing structures and is known for its high strength and reliability.

We choose S355 steel because it provides a strong and durable base for our shelters. The material is well suited for outdoor use and complies with European standards.

In some cases, a permit is required for a shelter. Whether this is the case depends on various factors, such as the location, how long the shelter will remain in place and what it is used for. Always check with your local municipality for the applicable requirements.

Our shelters are designed according to the European standard EN 13782. To support your permit application, we have already prepared the most important technical documentation for you. We provide the buildbook free of charge, including the construction drawings, technical details and structural calculations. These documents provide insight into the safety and stability of the shelter and can be used for your permit application.

Our warehouse in Babberich holds a large stock of shelters, allowing us to process orders quickly. If your order is in stock and payment has been received, we can hand it over to our transport company within two days. This results in a delivery time of approximately one week within the Netherlands and one to two weeks for deliveries to Germany.

A separate installation manual is available for each frame and cover. You can find this manual both in the packaging and online, where it can be downloaded per product.

There are two ways to install the cover on the frame. Which method is suitable depends on the size of the shelter.

For smaller shelters of approximately 4 to 8 metres, the cover can be pulled over the frame using ropes. For larger shelters from approximately 10 metres, we recommend rolling up the cover compactly, placing it on the ridge with a crane or aerial work platform, and then unrolling it carefully towards both sides.

This method is safer, easier and less sensitive to wind. Do not install the cover in strong winds and always check the manual for the full instructions.

The covers are packed in boxes, while the frames are delivered in steel and wooden crates. Keep the packaging to store or transport the product again later. If you do not reuse it, the packaging can be disposed of.

Regularly check the tension of the ropes, tension straps and wind bracing, especially after periods of strong wind or heavy snowfall. Remove snow in time to prevent overloading.

Also make sure that the flap of the cover is pulled properly over the frame. This prevents wind from getting underneath the shelter. All of this helps extend the lifespan of your cover.

Yes, it is possible to order spare parts if something breaks on your shelter. In most cases, damage to the shelter can be repaired by replacing a specific part. We offer these spare parts in sets. You can download an overview of these additional parts per product from our website. Not sure what the right solution is?

Would you like to increase the visibility of your company? Then printing your cover is an excellent option. All shelters can be ordered with a printed cover. You can choose white PVC as the base material. Upon request, you will receive a 3D impression of your design. After order confirmation, we deliver within 4 weeks.

In our 3D configurator, you can configure your shelter and view the options for a printed cover. This gives you a better impression of what your shelter could look like.

Yes, all our standard products are supplied with structural calculations, which are available upon request at no additional cost.

We work with specialized engineers to ensure that all calculations comply with the EN13782 standard. This guarantees broad acceptance in Europe and internationally.

To maintain their legal validity, we only provide these documents in their original German or English version. If needed, you can use these documents as a reference so that a local engineer can prepare a structural calculation that meets the specific requirements of your country.

The exact distance between the concrete walls can be found in the product drawing. This applies to both a single setup and a configuration with multiple shelters placed side by side.

Concrete blocks, also known under brand names such as Legioblocks, megablocks, stackable blocks, concrete Lego blocks or stackable concrete blocks, form an excellent base for bunker silo shelters. For installation on the blocks, it is important that the top surface of the blocks is level. Refer to the drawing for dimensions and instructions.

Make sure the distance between the walls matches the dimensions of the desired shelter. Refer to the shelter drawing for the exact measurements.

The placement of multiple bunker silo shelters affects the allowable distance between the walls and the attachment to the wall. Therefore, the tolerances differ compared to the installation of a single shelter. Refer to the drawing for explanation and exact dimensions.

You can extend the shelters indefinitely in lengths of 6 meters. This can be done easily and without modifications to the product. The connection (overlap of the cover) is fully wind- and waterproof once the ropes are tightened.

To ensure that your concrete wall can safely support the additional load of a bunker silo shelter, we strongly recommend consulting a structural engineer for a professional calculation. This is especially important in the following cases:

When the wall height exceeds 2.6 meters
When the free span is greater than 8 meters

A structural calculation verifies whether your concrete wall is strong and stable enough to carry the additional load. If needed, we can connect you with a qualified structural engineer who can perform this assessment for you.

Our sales team will be happy to think along with you about the right solution for your situation.
