The significance of torque wrench management in rebar installation lies in its simplicity.
Hello, everyone. This is Enta. When an inspector asks you, “How do you tighten the nuts when finishing the heads of rebar inserts?” how do you respond? The Slope Protection Association’s cost estimation guidelines specify the use of a torque wrench, so you’d say you use a torque wrench, right? Geotechnical engineering…
Here are three methods for adjusting unevenness during backfilling by rebar installers
Hello, everyone. This is Enta. How do you handle the back surface when inserting rebar?

To begin with, cement slurry is a paste-like grout made by mixing cement powder and water. In slope stabilization work, it is used in ground anchor work, rock bolt work, rebar insertion work…
A Review of Self-Drilling Rock Bolts
Hello, everyone. This is Enta. You’re familiar with self-drilling rock bolts, right? Conventional drilling: A drilling machine is used with a dedicated drill rod to create the hole, into which rebar is inserted. Self-drilling: A drilling machine is used with a self-drilling rod, and the grout is injected directly into the hole to complete the process. Basically, self-drilling is used when the rock mass is not stable enough to support itself…
When drilling hard rock with a lightweight drill rig, a down-the-hole hammer is the most effective method.
Hello, everyone. This is Enta. It’s the last month of the fiscal year!! Let’s stay safe!!

As labor shortages intensify, we’re seeing more and more worksites where rates are high but staff is scarce!
Hello, everyone. This is Enta. We’ve recently started taking on small scaffolding projects as well. Actually, there’s a reason for this—it’s simply because there aren’t any scaffolding contractors available, lol. For large projects, there’s usually enough money to secure one, but for small projects, the budget is tight…
