We finish covering the top line along the backrest. First we create a concrete retaining wall with 3mm forex that will support the road above.

Let’s now cover the gallery; the space in height is too little, we cannot use polystyrene, therefore we use a plastic mesh to be coated with paper.

We strengthen the covering with scagliola (marble powder); therefore we also shape and position the road above the tunnel.

We apply a base of sieved soil. The area is ready for vegetation.

Before continuing we must solve a problem. The path of the upper line in the section visible in the picture is very close to the furthest track of the station. The coverage is therefore quite steep. An escarpment or a rocky ridge might be the solution, but it doesn’t seem like an “neat” alternative. So we draw inspiration from reality again. From years apart, the sprayed concrete technique or “spritz beton” is used to consolidate embankments or excavations.

We then shape a block of polystyrene that will cover the hollow (highlighted in red in the picture above).

We apply a plastic mesh as imitation of a real wire mesh commonly used for this construction technique.

We coat the chunk with plaster and apply the anchor props. The mesh can be glimpsed in some points, as in truth.

We connect the block with the landscape.

Let’s complete the work with the vegetation.

The top line coverage is finally over. The next step is the final coverage of the helical. In one corner of the photo you can see a gate … the access to the accommodation whose construction phases are found in this article.
