Top 5!!"},"content":{"rendered":"

Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

I'm swamped with planning next week's event, designing my daily routine, and doing cost estimates lol<\/p>\n

If I don't keep finishing them up and sending them out, they'll just keep piling up one after another...<\/p>\n

I'll do my best lol<\/p>\n

\n

But that's beside the point.<\/p>\n

Lately, we've been getting more requests for stone masonry again, but,<\/p>\n

For now, I\u2019d like to explain what kinds of stonework are problematic.<\/p>\n

 <\/p>\n

Case 1<\/span><\/strong><\/span><\/p>\n

\"Stone<\/p>\n

First of all, a stone wall with vertical cracks like this is one that was on the verge of collapsing but somehow managed to hold together.<\/p>\n

This means they had already been subjected to some kind of internal pressure.<\/p>\n

Sprayed Mortar (+Reinforcement Installation)<\/strong><\/span><\/p>\n

I think the basic premise is that these should be used in combination.<\/p>\n

 <\/p>\n

Case 2<\/span><\/strong><\/span><\/p>\n

\"Dry<\/p>\n

Stone walls with such wide joints are gradually eroded by rainfall, and<\/p>\n

It crumbles away as if the stones were being pulled out.<\/p>\n

Therefore, the grout lines must be completely redone, and measures must be taken to prevent them from cracking.<\/p>\n

Financial Health: 5<\/span><\/strong><\/span>0%<\/span><\/strong><\/span><\/p>\n

 <\/p>\n

Case 3<\/span><\/strong><\/span><\/p>\n

\"Stone<\/span><\/strong><\/span><\/p>\n

There are also places like this where natural stones have been stacked up.<\/p>\n

This stone wall is made of some pretty large boulders, but I think it\u2019s quite sturdy and won\u2019t collapse easily, given their size.<\/p>\n

It's put together skillfully and doesn't fall apart right away, but we sometimes get called in to help with weed control, lol.<\/p>\n

Weeds growing in the soil can also cause it to become loose.<\/p>\n

Risk Level: 70%<\/span><\/strong><\/span><\/p>\n

There is a possibility that it could lose its balance and fall due to an earthquake, but if it isn't very tall, it might be okay.<\/p>\n

 <\/p>\n

Case 4<\/span><\/strong><\/span><\/p>\n

\"Dry<\/p>\n

In cases where the dry stone wall is already beginning to collapse (e.g., cracks have formed, stones are protruding, or stones have fallen out)<\/p>\n

Since it's already collapsing, there's a high chance that heavy rain could cause it to collapse all at once.<\/p>\n

Because the joints are so large, there is a high likelihood that the amount of soil particles inside has decreased significantly.<\/p>\n

It is extremely dangerous, especially if it is 3 meters or longer.<\/p>\n

We recommend using these together!<\/p>\n

 <\/p>\n

Case 5<\/span><\/strong><\/span><\/p>\n

\"Rubble<\/p>\n

This is a rubble-stone wall.<\/p>\n

Even though the joints in this type of stone wall are still somewhat intact, the stones can easily fall out if the wall is deteriorating.<\/p>\n

Surprisingly, rubble-stone walls are often built on steep slopes, and if an earthquake strikes, they\u2019ll collapse in an instant.<\/p>\n

Also, since they aren\u2019t piled as high as you might expect, the risk is relatively low, but the impact on homes if they were to collapse would be incalculable.<\/p>\n

Risk Level: 50%<\/span><\/strong><\/span><\/p>\n

\n

We've covered Cases 1 through 5.<\/p>\n

Please take a look at the stone or block walls on your property.<\/p>\n

Please think of this \"soundness\" rating such that 100% soundness means the company was just established (newly founded).<\/p>\n

 <\/p>\n

From that point on, its soundness gradually deteriorates due to aging.<\/p>\n

If a stone wall has been subjected to a major earthquake, its structural integrity will decline sharply.<\/p>\n

In areas that have been hit by heavy rain time and time again, the structural integrity will continue to deteriorate.<\/p>\n

 <\/p>\n

For now, please check it out.<\/p>\n

I'll write about how to inspect and check things again tomorrow!<\/p>\n

 <\/p>\n

See you later.<\/p>\n
