DSI Hollow Bar

Key Features

The main advantages of the DSI Hollow Bar are:

• Fast drilling and placing due to drilling, anchor installation and grouting in a single operation.
• Neither separate anchor installation nor removal of casing and drill rods.
• Similar installation methods for all ground conditions.
• Choice of drill bits for different ground conditions.
• The hollow core not only serves for flushing with air or water during drilling, but also for grouting the anchor tendon.
• Flexibility in length by using couplers.
• Ability to work with small drill rigs without casing in restricted headroom conditions.
• Accommodation of needs for enhanced protection against corrosion upon request.
• The accepted high standard of quality control from production stage to installation of the DSI Hollow Bar Anchors ensures consistent quality.
• The DSI Hollow Bar Anchor has an advantage in all applications where normally cased drilling is required.
• The DSI Hollow Bar Anchor System allows for anchoring in both cohesive and non cohesive ground, even under limited space conditions.
