This is the best spot for the cutout in the zabuton frame!
Hello, everyone. This is Enta. Are you putting void tubes in your zabuton frames? I’ve talked about this before lol. But since I get asked about it a lot, I’ll write about it again lol. In actual practice, the finish looks better if you don’t use void tubes. There’s no doubt about that…
Maximum Limits for Legal-Frame Construction in Confined Areas
Hello, everyone. This is Enta. Do you know the minimum construction clearance for steel-frame construction? What I’m getting at is, on a cramped job site, how close to the structure behind can you actually work? There are some super tight spots when doing work on steep slopes, you know~ lol. Even the designers…
Results of My Investigation into Shortcuts, Sloppy Work, and Construction Defects in Slope Construction (Part 5)
Hello, everyone. This is Enta. It’s been feeling a lot like the rainy season lately. Things are getting dangerously slow for us slope contractors… Just like last year, the situation remains dire, but it seems like only the big companies are doing well… We small and medium-sized slope contractors are really in a tight spot, but we’ll hang in there and keep pushing forward…
This might be the reason why the rock drill isn't drilling holes properly!!?
Hello, everyone. This is Enta. Do you use rock drills? When it comes to large rock drills, there are suspended drilling rigs, and for small ones weighing 50 kg or less, there are rock drills like this one. This is about the size of a small, handheld model. When using air tools like these…
The solution for water leaks in sprayed concrete is to use a rapid-setting agent, but that’s actually quite difficult.
Hello, everyone. This is Enta. Have you ever used a quick-setting agent? I think it’s often used in places where water seeps out on slopes. If you mix it while spraying, it sets in just a few seconds, so it comes in handy sometimes, doesn’t it? But it’s hard to mix properly, lol. Where should you mix it? Plastic…
It's Okay If Things Don't Go Smoothly on the First Day of Construction | Getting Used to the Job Site
Hello, everyone. This is Enta. I’ve been doing mortar spraying on slopes for the past few days, and it’s really tough working with fresh mortar delivered by concrete mixer trucks, isn’t it? I usually order a 1:4 fresh mortar mix instead of dry-mixed mortar, but it starts to harden as time goes by... So I’m trying every trick in the book to get the job done...
Found a Great Product! (OKM-50L Water Flow Meter) | Grout Management
Hello, everyone. This is Enta. Do you use water meters? Lately, I’ve been seeing them used quite often in ground anchor construction projects and for shotcrete work. I even tried using one at a job site I was working on the other day. The reason is that if the general contractor awards points for innovative ideas, I try to use them as much as possible…
What You Need to Know About Installing Window Frames (Part 3) | Real-Life Examples
Hello, everyone. This is Enta. Here are the pros and cons of installing formwork along a slope. Pros: 1. The amount of mortar used is limited to the design quantity plus a small amount for waste. 2. Less work is required because there are fewer areas where reinforcement mesh needs to be used. 3. Since the depth isn’t great, construction progresses as scheduled. 4. When viewed from the front…
What Happened Next After I Wanted to Protect the Hose Couplings for Spray Materials!
