Hello, everyone. This is Enta. When you’re tensioning ground anchors, you attach a dial gauge or digital meter to the jack side, right? That’s to measure the elongation of the prestressed steel strands. It’s not enough to just check the tension load—you need to verify both the load and the elongation. For beginners…

Hello, everyone. This is Enta. Not many people can really explain the weather resistance of those leveling mats that go under the load-bearing plates in ground anchor construction, right? lol That’s because nobody’s interested, lol (it’s the kind of thing manufacturers just mention in passing). “Well, it’s PE (polyethylene), so…”

Hello, everyone. This is Enta. When you’re working on ground anchors or inserting rebar, you put rust-preventive oil inside the caps, right? That’s actually a petroleum product (mineral oil). Well, I’m sure you already know that, lol. It is made from naturally derived raw materials, but if it leaks into the soil or water, it doesn’t really break down…

Hello, everyone. This is Enta. Water came out of the PC strand!!! What should you do in a situation like this!? (Part 1) This is a continuation from last time. For some reason, water started coming out of the head of a ground anchor. The most likely causes are probably something happening nearby, a change in the water table, or an earthquake…

Hello, everyone. This is Enta. When installing ground anchors, water sometimes comes out of the head, right? From between the PC strands, lol. You’d think, “It’s surrounded by grout, so there’s no way water could get in, right!?” Of course, manufacturers use epoxy to prevent water from getting in…
