Construction DX can’t be achieved without incorporating some level of automation, but once it’s in place, it makes things easier.
Hello, everyone. This isENTA. The other day, our fourth water meter arrived. It has an Okasan Kiko sticker on it, but I’m going to peel that off and put an ENTA sticker on it instead lol. The reason I bought this water meter is that we’re using it as part of our quality control initiatives. …

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…
What the heck is weather resistance?!
Hello, everyone. This is Enta. Continuing from last time, here’s the leveling mat used on the underside of the load-bearing plate. The truth about its weather resistance has finally come to light! lol Claims that it’s “weather-resistant” have hardly been verified at all! However, as for cross-linked polyethylene, it is weather-resistant…
