I Tried Measuring Positioning Errors in Drainage Boring Work!
Hello, everyone. This is Enta. It’s gotten quite a bit cooler in the shade. But air-conditioned workwear is the best this time of year! The real benefit of air-conditioned workwear is how it handles the lingering summer heat, lol. It makes the lingering summer heat feel like autumn all at once, so you can get your work done comfortably. But anyway… Since last week, I’ve been working on draining the water…
I Tried Core Drilling Using the Wireline Sampling Method!
Hello, everyone. This is Enta. I’ve been using a new tool for my work since a few days ago. It’s called a Soundscope. Have you heard of it? It’s a stethoscope that lets you listen to the sounds transmitted through metal. With the current “wireline” method, core boring…

If water is seeping out even at a site where no drainage boreholes have been drilled, you should have them installed!
Hello, everyone. This is Enta. Lately, when I’m working on projects like rebar insertion, there are often spots where I think, “We’re in trouble if we don’t add drainage here.” For projects we design in-house, we always make sure to include drainage in the design.

Anyway, getting back to the topic at hand—I’ve been getting a lot of requests for stone masonry work again lately, but for now, how should I put it…
Mastering the Movement of Water | Learning About Water Control from Watersheds and Sediment-Related Disasters
Hello, everyone. It’s Enta here. Hasn’t this weird rain been really bad these past few days? All over the country! And there have been a lot of earthquakes, too... It was pouring so hard that I decided to film it lol. The water level at Asukabu in the second half of the video was absolutely massive, and it kept rising afterward until it reached about 80% of the maximum height...
It turns out there are actually many misconceptions about the water used in dewatering drilling operations to drain water from mountains.
Hello, everyone. This is Enta. Since the rainy season is just around the corner, today I’d like to talk about drainage. I’m going to write about a common misconception among drainage well contractors. Well, generally speaking, rain falls from above, lol. On mountains, water seeps in from above in some areas, while in others it flows in from far away…
About Nominal Diameter | The Difference Between a 90 Drilled Diameter and Actual Dimensions, and Cement Calculations
Hello, everyone. This is Enta. The other day, Ishio-kun, a construction-themed YouTuber, came to visit our company! We went together to tour a construction site where Enta is the primary contractor for Ishio-kun’s construction channel, and he interviewed us about all sorts of things lol. The general contractor also kindly gave us permission to mention their name…
What Are the "Essential Management Practices" for Drainage Boring? | Tips for Preventing Variations
Hello, everyone. This is Enta. From a craftsman’s perspective, I think there are aspects of construction management that seem familiar but aren’t fully understood.
