When it comes to formwork for rebar insertion and ground anchor work, void pipes offer better quality! (For Designers)
Hello, everyone. This is Enta. When it comes to cutting out openings for rebar insertion or anchor installation during the design phase, what do you think is the best approach? I think designers probably already decide which material to use based on their past experience. And they just take it for granted that…
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!?

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.

The Anchorhead Situation in a Few Years
Hello, everyone. This is Enta. I’m currently working on load relief at a construction site where work is underway. I’m relieving the load on an anchor that’s been under tension. I haven’t checked to see if it’s been retensioned afterward. What I want to point out is the rust on the head. It’s an anchor that’s been in place for several years now…
