For some reason, we’ve gone from the basics of landscaping to discussing spray thickness, lol.

Since we're connected, I'll let it slide lol

 

Last time, we checked the spray thickness based on hardness.

Next, I'll check another source.

Japan Road Association: Guidelines for Slope Construction and Slope Stabilization

Here is the selection process.

I'm sure administrators have seen this before.

First, let's talk about the slope.

If the slope is steeper than 1:0.8, reconsider (depending on the condition of the natural ground).

There are red arrows in this table, which was created in Excel, and

We'll draw the lines to fit the site.

We will determine (evaluate) the thickness based on several types of data.

If you consider only one option, your thinking can become biased, so it’s important to compare and evaluate your options.
