Attach slope with gabions - explained step by step

The Content Of The Article:

Gabions have become increasingly popular in recent years. No wonder, because they are versatile. For example, they can be used to attach a slope very well.

Gabions can be filled in a variety of ways

At first you only saw them as fences or screens. Now they are true all-round talents. We are talking about baskets filled with stones. Also called gabions. These stone baskets can be used to build screens and noise barriers, flower beds and raised beds, seating, fire pits and much, much more. With gabions you can also fix a great slope.

Hang can become a source of danger

Although a slope looks pretty nice, it can also be dangerous. Especially if he was not attached. Then it can happen that the floor is washed away in the rain. If you have a garden with a slope, you should always attach it for safety reasons.

This works e.g. very good with gabions. There are even special gabions for it, which have an L-shape and serve perfectly as a retaining wall. The shape of the gabion reliably supports the soil behind it. The only problem: these L gabions are not everywhere. I have it for example found on Here they are available in the dimensions 80 x 100 cm (H x W), 100 x 100 cm and 60 x 100 cm. Or even bigger (120/150/170/200 x 100).

Of course you can also attach the slope with plant rings. That looks nice too. If you like it modern, you should prefer gabions. They support the slope safely and can also be set up much nicer than plant rings. Gabions can eventually be filled with a wide variety of materials. For example, sandstone, basalt, granite, pebbles or broken glass can be used. The latter can even illuminate you indirectly. In addition, gabions are easy to transport, built in no time and very stable.

How to attach a slope with gabions

Step 1:

If you want to fix a slope, you first have to create a solid surface. Lift a foundation with a depth of about 35 centimeters and a width of about 40 centimeters.

Step 2:

To ensure that the gabions are properly fixed later, it is advisable to place the mesh baskets on a damp concrete foundation made of stamped concrete. In other words, place the gabion in the stamped concrete, align it with the spirit level and then pour concrete into the smaller part of the mesh basket again. Then string together basket by basket.

Step 3:

Now you can fill the gabions too. You can choose from sandstone, basalt, marble, granite, pebbles or broken glass. You are spoiled for choice here. Allowed is what pleases. For some ideas on how the filling can look, you can visit I personally like, for example, the variants with the glass break stones and the tree trunks very well. The grain size of the quarry stone filling must always be slightly larger than the mesh size of the steel grid.

Step 4:

Now you have to equip the back of the gabions with a drainage layer. For example, you can backfill the stone baskets with gravel. You can also lay a filter fleece behind the gabions. Better is a dimpled sheet. Then fill everything with topsoil.

Step 5:

In principle, you are already finished fixing the slope. Since the whole thing looks a bit sparse, we recommend planting the fortified slope. In principle, you can plant everything you want on the surface of the earth.

If you like, you can also plant the interstices in the gabions. Pick locations to fill a mixture of equal parts potting soil and coarse gravel. By the way, this works very well with a small spoon. Then you have to put the small plants deep into the joints and fill everything with substrate.

As you can see, it's not hard to fix a slope with gabions. In addition, in general and in terms of slope mounting, they offer some advantages:

  • easy to transport
  • built up fast
  • very stable
  • just need a simple foundation
  • versatile filling

Just think about the material with which you fill the gabions. Finally, the filler material should match the style of the garden.
