ESPT Provides Advanced Self-Drilling Hollow Bar Solutions
Self-Drilling Hollow Bars
Self-drilling hollow bars (SDHBs) are versatile construction tools used in geotechnical and civil engineering applications. They combine drilling, grouting, and anchoring into a single operation, making them highly efficient for challenging ground conditions.
Self-Drilling Hollow Bars
ESPT offers supply and installation of self drilling hollow bar for wide range of application in Saudi Arabia, Egypt, United Arab Emirates and other Gulf countries.
Key Features
- 01Hollow DesignThe bar is hollow, allowing grout to be pumped through its center during installation. This ensures proper bonding with the surrounding soil or rock.
- 02Self-Drilling CapabilityEquipped with a sacrificial drill bit, the bar can drill directly into the ground without the need for pre-drilled holes or casing.
- 03Threaded SurfaceThe bar's surface is threaded, enabling it to act as a reinforcement element once installed.
Applications
- 01Soil NailingStabilizing slopes and retaining walls.
- 02MicropilesProviding foundation support in weak soils.
- 03Rock BoltingReinforcing rock masses in tunnels and mines.
- 04AnchoringSecuring structures like retaining walls or bridge abutments.
Advantages
