Build your own carport – safely stabilize slopes with gabions
Securing the slope with a gabion wall was the final task in our “Build your own carport” project.
Our double carport was finally finished. The roof turned out to be tight, and I had applied the paint several times to ensure long-lasting quality and protection.
Once I had installed the electrics, LED lighting, motion detectors and a surveillance camera, the interior of the carport was as good as complete.
Now I turned my attention to the final slope stabilization behind and next to the carport.
In addition to the solid, steel-reinforced formwork stone wall, I planned to erect a decorative gabion wall in the front viewing area to provide additional stabilization and aesthetic enhancement.
The slope by the carport must be secured
I had already intercepted and secured the small slope on which the carport was erected. The formwork wall that I built on the west and east sides served as a boundary between the slope and the pitch.
I described the construction of this formwork stone wall in the entry Building a carport yourself – securing a slope with formwork stones and documented it there with a video.
However, the transition from the formwork wall to the driveway on the north side was not yet secured. At this point, the earth slope slowly ran out into the driveway.
Although this has not been a problem in the past, even during major storms with heavy rain showers, this area was not very visually appealing.
I therefore decided to box up this area too. As is so often the case, I used gabions to secure the slope.

Video: Securing a slope with designer gabions
I recorded the construction of the gabion wall at the carport again in a video. All steps, from digging the soil to filling the gabions with stones, can be seen there.

Installation of the gabions across the corner
The installation of the two gabions turned out to be less complicated than expected. First, I leveled the ground along the alignment of the formwork wall. I excavated a short section that protruded into the slope and also brought it up to the level of the wall.
As the ground had grown naturally and was therefore very firm and stable, I didn’t need an additional foundation for the gabions.
I first assembled the gabions individually using the spirals and aligned them around the corner on the slope. I still had to remove some soil in places before I could align the stone baskets perfectly in terms of angle and level.
I then fastened the two gabions together with cable ties. I fixed the grilles very tightly with the cable ties.
This was necessary because I had removed the spirals at the corners of the respective gabions in order to then turn them through the grids of both stone baskets at the same time. In this way, the two baskets were firmly connected and the grids stabilized.
- Stabile Gabione mit Maschenweite 5 × 10 cm und 4 mm Drahtstärke – aus galvanisch verzinktem Stahl, wetterfest und langlebig für Gartenmauer, Sichtschutz oder Zaunbau.
- Abstandshalter verhindern das Ausbeulen der Gitter und geben den Gabionenwänden dauerhaft eine gerade Form.
- Vielfältige Einsatzmöglichkeiten: als Stützmauer, Steinkorbzaun, Hochbeet-Einfassung oder dekorative Steinkorbwand.
- Geeignet für Natursteine und Glasbrocken ab ca. 8 cm Größe – die Maschenweite sorgt für ein stabiles, gleichmäßiges Erscheinungsbild.
- Montage mit C-Ringen – sichere Verbindung der Drahtgitter, inklusive kostenloser C-Ring Zange für schnellen und unkomplizierten Aufbau.
I stabilized the lower section of the gabions with concrete screed. To do this, I poured several bags of ready-mixed concrete into the lower area, watered it and tamped it down well.
I also firmly connected the stone basket along the formwork stone wall to the wall. The new slope stabilization was now safe and stable.
To prevent the soil from pushing through the stone baskets, I attached a protective fleece to the back of the baskets.
I also fitted the spacers, which keep the opposing grilles at a parallel distance and prevent the baskets from bulging.
The new retaining wall on the slope was finally completed when the gabion wall was filled.
As a result, I have created a raised bed around the carport, which is held in place by my formwork stone wall and the gabions.

Summary and conclusion
Once our double carport was fully assembled and the roof sealed, I concentrated on the final work.
I had already installed the electrics, LED lighting, motion detectors and a surveillance camera, which almost completed the interior of the carport.
The next step was to secure the slope behind and next to the carport.
In addition to a solid, steel-reinforced formwork stone wall, I decided to erect a decorative gabion wall in the front viewing area to ensure both stabilization and aesthetic enhancement.
The installation of the gabions proved to be uncomplicated. I leveled the ground, excavated a short section of the slope and did without an additional foundation due to the firm, natural subsoil.
After assembling the gabions and aligning them, I was able to connect them firmly together and stabilize them with concrete screed.
Finally, I installed spacers to keep the gabion grids parallel and without bulging, and created a raised bed around the carport, which is supported by the formwork stone wall and the gabion wall.

FAQ on slope stabilization with gabions at the carport
1. why was it necessary to secure the slope at the carport?
The earth slope next to the carport was previously unsecured and leaked into the driveway, which did not cause any acute problems, but was not visually appealing. Slope stabilization with gabions should offer both stability and aesthetic enhancement.
2 What are the advantages of a gabion wall?
Gabions offer a flexible and permeable solution for slope stabilization. They adapt to the natural movements of the substrate and enable effective drainage, which reduces the hydrostatic pressure on the wall. They are also durable and require little maintenance.
3. why was no additional foundation used for the gabions?
As the subsoil was firm and naturally grown, no additional foundation was required. The stable ground provided sufficient support for the gabion wall, which simplified the construction process.
4. how were the gabions connected to each other?
The gabions were first assembled using spirals and then fixed in place with cable ties. The spirals at the corners of the gabions were removed so that they could then be turned through both grids at the same time to create a solid connection.
5 Why was concrete screed used in the lower area of the gabions?
The concrete screed was used to additionally stabilize the gabions and reinforce the lower area of the stone baskets. This contributed to the secure anchoring of the gabion wall.
6. what measures have been taken to prevent the soil from pushing through the gabions?
To prevent soil from pushing through the gabion grids, a protective fleece was attached to the back of the baskets. This fleece retains the soil while the water can continue to drain away.
7. what are spacers used for in gabions?
Spacers keep the opposing grids of the gabions at a parallel distance and thus prevent the baskets from bulging. This increases stability and ensures a uniform appearance.
8 What role does the formwork wall play in slope stabilization?
The formwork wall was erected as a solid, steel-reinforced retaining wall on the sides of the carport. It serves as the main support for the slope and complements the gabion wall, which provides additional stability and an attractive appearance in the front viewing area.
9. how was the gabion wall connected to the formwork wall?
The gabions were firmly connected to the formwork stone wall to ensure continuous stabilization of the slope. This connection provided additional safety and stability.
10. how was the transition between the slope and the driveway designed?
After installing the gabion wall, a raised bed was created around the carport, which is supported by the formwork stone wall and the gabion wall. This gave the area an appealing structure and provided a clear demarcation from the driveway.
