KEco Soil-Nail is used to improve the stability of natural slopes or artificial slopes caused by excavation, which are at high risk of collapse.
KEco Soil-Nail uses the same solid / hollow type as KEco Rockbolt, and it is easy to construct and it is possible to build a stable retaining wall by using the ground itself as a wall. In particular, it has been widely commercialized due to its superiority in safety, constructability and quality.

Lightweight (4kg/4m) for easy to handle · KEco solid rock bolt can be installed by one person · KEco solid rock bolt can be installed by one person · There is almost no dropout due to its own weight when working on the end of the ceiling. · Easy to insert KEco solid rock bolt compared to steel rebar · Difficulty working in the water section |
Lightweight (4kg/4m) for easy to handle · KEco hollow rock bolt can be installed by one person · it Can be injected through a hollow hole without connecting a separate injection tube · It is possible to shorten the construction time and to fill it by 100% · Excellent effect in the work of the water section |
| Stability |
· KEco solid rock bolt can be inserted by humanpower · KEco solid rock bolt can be inserted by humanpower · it is a non-conductive product, it can be used safely even in high-moisture and high-pressure sites. |
Reduced risk factors with lightweight materials and excellent workability · Stable excavation cycle management is possible by reducing worker fatigue and increasing work efficiency · Workers can check the mortar filling status by themselves · 100% filling possible (prevention of falling accidents) · Zero safety accidents by ensuring quality and minimizing risky work |
