protec Silo Bags – Now available pre-filled!

Gravel instead of sand – the optimal filling!

protec silo bags are filled to two-thirds with fine gravel (grain size 2/8). This corresponds to approx. 17 kg for the 120 cm version and 12 kg for the 90 cm version. This ensures excellent stackability and easy handling. Thanks to the integrated carrying loop, two silo bags can be carried comfortably at the same time. Silo bags filled with gravel do not absorb water, which means they remain flexible, durable, and easy to handle even in wet conditions. The filling is not washed out by rain and does not freeze into a solid block during winter. Thanks to their flexible shape, the bags fit closely to the silo surface, creating a tight, gap-free barrier.

The Better Silo Protection

Silo bags (commonly referred to as sandbags) are significantly more effective for securing silos than the car tires still often used. There are several reasons for this:

• Silo bags can be arranged to form a continuous barrier that minimizes air ingress beneath the cover sheet, reducing mold formation along the edges. In contrast, car tires always create air gaps, which in the worst case can extend across the entire silo.
• Handling the bags is much easier and more efficient — not only when covering the silo but also during feed-out after opening. This saves time and reduces physical strain.
• Depending on their condition, tires may release wire fragments. If these enter the silage and are ingested, they can cause serious harm to animals.
