Self-drilling anchors

These anchors consist of a hollow bar and a drilling bit suited to the different types of ground condition. They are recommended in cases where a cased hole is necessary. The main advantage of self-drilling anchors is their high efficiency, as several operations can be performed at once: drilling, installation of the anchor and sealing.

A few examples of application:

• Drilling in confined spaces (underground car parks, galleries, etc.),
• Drilling in loose ground or overburden.
