Slope stabilization – stack 2 gabions

Over a period of a few weeks, I built the first row of gabions over a length of around 30 meters. A relatively straight section was followed by a slight bend. By placing the gabions inside each other, I was able to form a corner on the south-east side.

Towards the end, the difference in height to the existing gabion wall was evened out using a gabion terrace.

The lower gabions are completely backfilled

These baskets were painstakingly filled with 80×125 granite stones over a number of weeks. The stones at the front were stacked in a visually appealing way.

This is where my many years of Tetris experience came in handy. On good days I was able to fill 3 baskets. However, you shouldn’t overdo it as the work is very hard on your back.

The granite stones were also carefully placed in the middle and rear sections of the gabion wall to maximize the weight and thus the stability. As the soil gradually slipped into the stone baskets due to the cold and wet weather, I had to hurry.

As soon as the gabions were filled with the stones, I attached the fleece to the back. Then I could fill the soil behind the stone baskets. The rain should then do the rest to compact the soil.

The 2nd row of stone cages is installed

Once all that was done, I could finally start assembling the second row of baskets. Starting with my existing gabion wall by the pool, I had extended the height of this old wall for a good six meters. This was followed by my terrace construction.

The difference in height between the baskets at the top and the baskets at the bottom was now exactly one meter.

My aim was to build the upper row of baskets directly on top of the lower row of baskets. Visually, this would result in a gabion wall consisting of one row of baskets on the west side and two rows of baskets on the south and east sides.

Video: Securing a slope with gabions

In the 7th part of my video series about the construction of the gabion wall that was supposed to support the earth slope, I went into detail about the assembly of the 2nd row of baskets. You can find the entire playlist of my videos here: Gabions for slope stabilization

Gabion assembly – Connect all grids together at the same time

My aim was now to place a second row of baskets on top of the first row of baskets in order to draw the raised level a good 15 meters around my slope. The second gabion row should then be angled into the slope and spatially separate the planned plateau above the gabion slope.

For this purpose, the new front and rear grilles were connected to the previous grilles and, of course, the middle separating grille with a spiral at the same time. Ideally, you should have at least 3 arms and hands for this work – or a second helper.

As I didn’t have a helping hand at the time, I had to do it on my own – and it worked! I put the grids together and fixed them in advance with cable ties if necessary. This procedure has made it much easier to screw in the spirals. In this way, the side panels were assembled one by one.

The cover of the first row was used as the base of the second row – i.e. just a grid in the horizontal plane between the two baskets. Everything was connected to each other with the spirals.

I had to secure the stone basket grids with the cable ties in advance, especially in the bend area. Sometimes there was already so much tension on the baskets that I needed help and had to press the grids together with pliers, for example, to turn in the spirals.

However, you must be very careful not to destroy the protective layer of the galvanized grids.

After a few days, however, this task was also completed. The protective fleece was again attached to the back of the 2nd row of baskets to prevent soil from being washed through.

At this point, it was also possible to see for the first time how the entire work fitted into the landscape. Only the stone filling of the upper row of baskets was still missing.
