Soil Water Retention
2025/08/26

Looking at the plants on site gives you a good sense of the terrain and soil moisture conditions. A prime example is bamboo!

Hello, everyone. This is Enta. When I go out to survey slopes, I pay special attention to the bamboo. Well, it’s not just the bamboo—but by looking at the plants growing there, I can get a rough idea of the soil conditions. “Bamboo groves = a sign of good surface water retention,” “willows and alders = a sign of valley bottoms or high groundwater levels…”

[Comparative Guide] Rebar Insertion vs. Ground Anchors vs. Retaining Piles (For Newcomers)

Hello, everyone. This is Enta. In this post, I’d like to compare the “Big Three” in slope stabilization. (It took me a whole hour just to draw this picture… lol) “Reinforcement Insertion,” “Ground An…,” and other methods you often hear about as countermeasures against slope disasters such as rockfalls and landslides…

Has the time come when subcontractors are being brought in by associations specializing in specialized construction methods and materials??

Hello, everyone. This is Enta. There are various associations in the slope stabilization industry—some for construction methods, others for products. I imagine the big companies don’t really think twice about buying materials, but for small businesses like ours, it’s pretty common to be unable to join these associations, lol. One of them is Gu…

Hello, everyone. This is Enta. How to Hoist a Drilling Rig onto a Slope (Part 1) How to Hoist a Drilling Rig onto a Slope (Part 2) In my previous post, I wrote about how to transport machinery using a cableway (log hauler). This time, I’ll discuss how to transport heavy loads at sites that use such cableways…

Design Changes for Similar Construction Methods Are Easy | An Era of Freedom in Choosing Slope Stabilization Methods

Hello, everyone. This is Enta. Lately, we’ve been shifting our focus slightly away from ground anchors to work on steep slope stabilization projects, where we’re using a method called the “unit net method.” Simply put, it’s a method where the heads of the rebar inserts are connected using wire or similar materials. Different companies have various methods…

The Type Whose Emotions—Joy, Anger, Sorrow, and Happiness—Are Their Driving Force | Slope Construction Specialist

Hello, everyone. It’s Enta. Starting today, the rest of the world is on a four-day holiday, but we’re operating as usual lol. The other day, an employee from a general contractor said something so outlandish that I was shaking with rage! (Not that I was “shaking with excitement,” though lol.) Well, I don’t plan on writing about it here, but it’s been a while since I’ve felt such strong emotions…

Even Simple Construction Work Should Be Done Thoroughly | Avoiding Complacency

Hello, everyone. This is Enta. I recently encountered a completely baseless accusation and I’m still a little shaken up, lol. People who don’t make any sense—whether online or in real life—are terrifying. But anyway, the other day, I was watching a recorded episode of a show called “The Unknown Gulliver.” It covered various major Japanese corporations…

The Mystery of the Floating Rock (Shore Protection Work) | The Wonders of Structure

Hello, everyone. This is Enta. I’d like to share a construction method I saw for the first time at a NEXCO job site. It’s the slope of a revetment. A mesh about 4.0 mm in size is stretched across the entire slope. Stones are attached to it. When I first saw it, it looked really strange, and I wondered, “How do they do that?”…
