Hello, everyone.
This is Enta.
Landscaping is one aspect of slope construction.
In terms of types,
1. Seed Spreader Operator
2. Seed Sprayer (commonly known as a "mud sprayer")
3. Vegetation Mat Installation
4. Sprayed Vegetation Substrate (t = ○○ cm)
1. Seed Spreader Operator
Mix seeds (such as forage grasses and native species), fertilizer, adhesive, fiber (paper scraps), and water, then spray the mixture.
Basically, we blow using the power of the pump without using compressed air or anything like that.
Use this in areas with a gentle slope where vegetation can grow easily.
2. Seed Sprayer (commonly known as a "mud sprayer")
In addition to the seed sowing described above, add a base material (leaf mold) and spray it on.
The installation method is the same as in 1.
Use on mountains with a slightly steep slope where vegetation can grow.
If the surface of the mountain looks like it might collapse or peel away, we attach a green net and spray it all together.
The results are a bit iffy, lol.
3. Vegetation Mat Installation
There are many types of vegetation mats, but the main distinction is whether or not they come with a fertilizer bag.
The seeds are scattered throughout the growing mat, and the fertilizer is sewn into it in a pouch.
It is well-suited to mountains with relatively steep slopes that are prone to erosion.
It is also used in areas where sprayed vegetation substrate cannot be applied.
4. Sprayed Vegetation Substrate (t = ○○ cm)
Generally, we apply a greening base material by spraying to create a solid soil foundation and then plant vegetation.
Simply put, even with hard bedrock, as long as the layer is thick enough, it’s not impossible to grow vegetation.
However, while in the past we used to use a 30 cm substrate depth for rock-face greening (20 cm of substrate sand + 10 cm of base material), this method is no longer in use.
So you're saying, "If you're going to go to all that trouble, why not just use sprayed mortar?"
Back then, there was more emphasis on greening than there is now.
Lately, most of the work has been spray-applied mortar.
In the end, while it’s great that we’ve added greenery, the question becomes, “Who’s going to weed it?”
Plus, when it comes to slope work, it’s something a layperson can’t do—it’s really tough, isn’t it?
So we started with sprayed mortar right from the beginning.
Well, I guess that's just the way things are these days.
It seems that even greening has its pros and cons these days.
By the way, I believe the Slope Association had a detailed decision-making—or rather, public relations—decision tree.
Once they've taken root, they don't look much different, but personally, I think the vegetation mats are the most stable option.
It comes with a mat until it grows, and it seems to be resistant to both heat and cold.
It doesn't get washed away that easily, even during sudden downpours.
See you later.
