I think it’s fine to do away with the use of trowels in spray-applied formwork work.
Hello, everyone. This is Enta. It’s already summer, isn’t it? Although the rainy season hasn’t officially ended yet. Here’s the projected end date for this year’s rainy season: Start and End of the Reiwa 6 Rainy Season (Preliminary Figures). There’s a chance of continued heavy rain, so let’s be careful out there ^^ But enough of that. Let’s talk about the legal framework. This…
The mortar inside the frames of a frame-type structure not only prevents weed growth but also helps prevent scouring and facilitates water flow for rapid drainage.
Hello, everyone. This is Enta. Last week, I went to check out a job site in Nagano. We’ve been working on this project for several years now, and the finished product really looks great. Even though it’s our own company, we’re doing a great job, lol. It’s a site along a river, and I can’t help but wonder, “Do we really need to do this here??”…
Here's how to calculate quantities for formwork in on-site spray-applied concrete construction.
Hello, everyone. This is Enta. You’re working on formwork construction, right? Do you know how to calculate the vegetation work and mortar spraying inside the formwork?

Here are three ways to minimize waste during spraying!

By the way, there’s quite a bit of waste during spraying, isn’t there? Do you know what that is? Even though the mortar was perfectly fine with no waste inside the sprayer, the material…
Why It's Important to Install Formwork Level (Horizontal) When Using the On-Site Spray Method
Hello, everyone. This is Enta. How do you install curbs? You might be wondering what I mean by that—do you install them according to the road’s slope, or do you install them strictly horizontally? The answer is that, regardless of the road’s slope, they should always be installed horizontally…
If you add colored powder to the mortar, you can create mottled-colored formwork and the like!
Hello, everyone. This is Enta. It’s gotten cold all of a sudden! It’s about time to get ready for winter. Let’s be careful out there. Especially our legs and lower backs, lol. Anyway, you recognize this color of frame, right? Do you? Here’s what it looks like up close. I took a close-up, but you can see…
Round steel anchor pins offer greater pull-out resistance!
Hello, everyone. This is Enta. When you’re laying the top layer of rebar and the bed is poor (the rebar slips in easily), do you use anchor pins made of deformed rebar or round bar? To answer that, it’s round bar. I used to think deformed rebar provided better friction, too. In fact, at first glance, the surface…

Hello, everyone. This is Enta. Do you ever get cracks in your sprayed concrete? You know, hairline cracks and sagging cracks—they’re bound to happen, right? lol I’m sure you’ve all put in a lot of effort to fix this. You might have tried slightly reducing the water-to-cement ratio, or adding fiber…
