It reliably slakes even in extremely hard mudstone, loam, and clay layers.
Hello, everyone. This is Enta. I heard the other day that an anchor came loose—lol. Apparently, the cause was a packer. Does using a packer increase the risk of it coming loose!? I actually think that’s almost never the case—lol (based on my experience). However, in this case, it seems to have come loose…

Case Study: Collapse of a Rebar Insertion Project | Why It’s Still Useful Even If the Grout Peels Away
Hello, everyone. This is Enta. Here’s a photo of a collapse at a rebar insertion work site. The mortar has come loose, and the rebar insertion work is being pulled downward. The design anticipated a surface collapse and called for a combination of mortar and rebar insertion work. The collapse occurred deeper within the structure. It collapsed after it rained…
If the cement slurry is too thick, do not add water to thin it out!
Hello, everyone. This is Enta. When you’ve mixed a few batches of grout, the grout left in the mixer tends to get pretty hard, right? What do you do in that case? This video shows what happens when you add something to that hardened grout! At first, it’s all clumpy…
How to Make a Packer for Ground Anchor Construction (Part 6)
Hello, everyone. This is Enta. I do a lot of construction training and instruction at our job sites. Just the other day, someone came all the way from Yamagata to conduct a training session on the Moldam method.

How to Make a Packer for Ground Anchor Construction (Part 5)
Hello, everyone. This is Enta. I’ve been in Odawara for the past few days! We’re currently carrying out reinforcement work to prevent a stone wall from collapsing in Odawara, and the project also includes some concrete repair work.

How to Make a Packer for Ground Anchor Construction (Part 3)
Hello, everyone. This is Enta. One of our younger staff members is setting up the net for the first time lol. It seems difficult for them to let the net hang down without snagging it. It reminds me of how we all were like this when we first started. It’s important to remember your beginnings! We should never forget where we came from. But anyway, back to the topic at hand—the packer’s…
How to Make a Packer for Ground Anchor Construction (Part 2)
Hello, everyone. This is Enta. It really feels like the rainy season, doesn’t it? Even though it’s summer... We just can’t seem to get any productivity out of our concrete work... It’s really frustrating, isn’t it? There’s only so much we can do to protect the work, and just when it feels like we’re finally getting started, we’re not making any progress. It looks like this is going to be a tough year in more ways than one...
