Drill Slime Is Useless | The Meaning of Gathering
Hello, everyone. This is Enta. You haven’t collected core samples from every single borehole, have you? They’re collected to verify whether the soil conditions at the site match the planned soil profile. But it’s even questionable whether those samples represent the same soil type. Well, it depends on the supervisor…
Collecting a Rare Burrowing Slime | Soil Analysis
Hello, everyone. This is Enta. I’ve been drilling at a certain job site since last month. It’s a temporary ground anchor project, and there’s a clay layer in Nagoya City called the Atsuta Formation. This clay layer is incredibly strong—it just won’t dissolve, lol. And as a result, we’re facing this situation…
Pressure Injection is Optional | Grouting Services
Hello, everyone. This is Enta. Do you have any standards (in your own mind) for the pressure applied during ground anchor installation?

All Different Miracles | The Slope Construction Site
Hello, everyone. This is Enta. The other day, I was looking at the drawings for a certain job site. It’s a ground anchor project, but the drawings say “rock bolt work.” The structural drawings show KTB anchors. I figured it must be a mistake…
Removal Limits for Removable Anchors | Retrievable Range
Hello, everyone. This is Enta. The local government asked me, “When it comes to removable temporary ground anchors, does ‘removable’ mean they can all be removed?” So I’m putting together some documents on that, lol. Here’s the basic structure of a temporary anchor: Load-bearing element, cable ties, polyethylene pipe (coating for PC steel strands), Po…
Expanding the Scope of Your Work | Skills in the Construction Industry
Hello, everyone. This is Enta. I’m truly humbled by all the calls I’ve been receiving from various sources lately. I’m handling them in the order they come in, but if you haven’t received a quote or other response yet, please send me an email to follow up. There’s a good chance I might have overlooked it (or forgotten about it? lol). I actually missed one today as well…
Guidelines for Project Management of Temporary Ground Anchor Work (Retaining Wall Anchors)
Hello, everyone. This is Enta. I’m at a job site where we’re installing temporary anchors for the third time. We’ve been doing a lot of temporary anchor work lately. That’s right. Since we’ve recently started taking on urban civil engineering projects, the number of times we’ve been called in has gone up, lol. We have three temporary anchor projects lined up by next year. (Including those currently in progress…)
