Hello, everyone.

This is Enta.

When you're installing a frame, there are times when a section just gives way completely and there's nothing you can do about it, right?

For example, something like this.

There's this huge gap, and it doesn't seem like we can bend the rules that much.

But it's actually pretty deep.

If left unattended, could it eventually crumble, develop cracks, or cause other problems?

It wouldn't be a problem if you finished it at the same time as sanding the frame, but considering the cost of materials, it's a waste.

Not to mention the materials—if we have to ask, “How many times do we have to blow into that hole?”—that’s going to cost labor as well.

It’s obviously better to get it done in one go, so I’ll explain how to do just that.

Simply put, if you backfill it first, it will be in the same condition as the other slopes.

A commonly used method for filling holes is soil-cement with a low cement content.

It's just a matter of mixing sand with sand and blowing it, isn't it?

The important thing here is,Must have strength equal to or greater than that of the natural groundThat's it.

However, I think the hassle of bringing the spray gun along before you start spraying is actually quite a bother.

There are also equipment-related factors to consider, as well as depreciation costs for items like compressors.

So, this is what I often use.

We use sand mixed with cement or debris from the excavated soil in the sandbags.

You can secure it with anchors or stack it for use.

Since sandbags are bag-shaped, the friction between them is somewhat greater (compared to loose soil).

Also, since it can be secured with anchors or similar fasteners, it’s easy to keep it in place.

By applying spray coating or erecting formwork over this surface, the job can be completed in a single step.

It's just this simple, but it's much better than having to go through the trouble over and over again.

From a purely environmental perspective, biodegradable sandbags (such as those made of hemp) are probably good for the environment.

I think even something like that can spark creativity and ingenuity. (If there are sharp ups and downs)

I hope this is helpful in some way.

See you later.
