frequently asked Questions
How can I determine the stone requirements of my Gabion?
On average, around 1.65 tons of stones are required for one cubic meter of gabions - depending on how carefully they are distributed. In addition, the value depends on the stone density and the gaps, so we cannot accept any liability for the calculated quantity.
Which stone size is suitable for my gabions?
The stone size depends on the mesh size and the depth of the basket. The mesh size of 5 x 5 cm is ideal for stones with a grain size of 32-56 mm. Stones for the 5 x 10 cm mesh should have a minimum grain size of 45-125 mm and for the large mesh size of 10 x 10 cm they should be at least 80-120 mm in size. Only small-grain stones are suitable for raised beds or gabions with a depth of 10 cm. The smaller the stone, the easier it is to achieve an even filling result.
What preparatory work is necessary before construction?
Due to the high weight of the filled gabions, the subsoil must be able to bear the load. Compacting the subsoil is therefore a good idea. However, you do not need to lay a complete foundation. The stone baskets are aligned horizontally. The anti-tilt device should be concreted in before the gabions are erected. Our recommendation: simply lay a garden fleece under the gabion so that no grass can grow into the stone basket.
How are gabions filled correctly?
After hanging the spacers, first place pieces of wood over them to protect them from stones falling down. You can pull the wooden poles out again as soon as a layer of stones is on them. Then place large stones into the baskets by hand. Place them as close together as possible and with the flat side facing the viewing surface. If the stones have a smaller grain size, you can pour them into the gabion. Simply use a bucket or a KG pipe for this. The stones are immediately in the desired place. The grids are also protected from mechanical stress.
We assume no liability for any damage to persons or other objects.

What are the spacers / standoffs needed for and are they included?
All of our gabions come with spacers. By hanging the spacers between the side grids of the gabion, the weight of the stones is evenly distributed across the grids. This prevents the grids from bulging. The spacers must be hooked in from front to back. Distribute the spacers evenly across the visible surface at a distance of 15-25cm.
We estimate around 15 pieces per square meter of viewing area. If you need more, you can purchase them HERE .
Our stable, round columns do not require any spacers. For square columns, spacers are only necessary for cross-sections of 32x32 cm or more.
Can the gabion grids be shortened?
Since the grilles are treated with anti-corrosive protection, cutting processes that generate heat (e.g. grinding or sawing) are not advisable. This will damage the protection. However, you can shorten the grilles with bolt cutters. When shearing, the galvanized coating extends over the edge of the cut surface and offers protection. An oxidation point forms in the middle of the cut surface, but this does not grow. If a hot-dip galvanized grille is cut, the cut points must be treated with zinc spray.
Dark spots can be seen at some of the weld points. Where do these come from?
The galvanic coating encloses the welding points during welding. This protects them from corrosion.
Freshly galvanized grilles still have slight traces of soot. These production-related stains are washed away after a few rain showers. There may also be white, powdery residues on the grilles. These production-related deposits are harmless. They will also be washed away by the rain over time.
Do I need a tipping device / fence post?
We recommend anti-tilt protection for heights of 100cm and less than 30cm. The posts are concreted into the load-bearing ground at a depth of approx. 60-80cm. If a foundation is already in place, post shoes can be used. Simply anchor these onto the foundation and push the posts over the long shaft. Then place the gabion over the posts. Please ensure that they extend at least two-thirds into the gabion! It is not necessary to attach the stone basket to the post. Filling it with stones not only conceals the posts, but also wedges the posts and stones so that the gabion stands firmly and cannot tip over.
For individual elements, at least two posts should be used, or at least one post per linear meter for gabions in a network.
Quality features of our wire mesh
Our wire has a diameter of 4mm . This value has proven to be the ideal thickness over the last few decades to ensure long-term stability and an affordable price .
The high shear strength of the welding points makes our wire mesh very stable . In addition, the wire has a higher tensile strength (>450 N/mm²) than other products.
The quality of the grids is checked at regular intervals by independent laboratories , where the shear strength of the weld points and the tensile strength of the wire are examined. A salt spray test is also carried out in accordance with DIN EN ISO 9227. This certifies that the grids have a durability of over 3,000 hours . The coating thickness is at least 275 g/m².
