Anchoring system

Self-drilling anchors are a bolting solution used for unstable soil conditions like sand, clays, silt, and gravel or in soft to medium fractured rock formations. - The mostly used method of installation is a rotary percussion. - The self-drilling anchor is used as a drilling rod during installation by use of sacrificial drill bit. - After using standard flushing methods (air or water), grouting is done with controlled pressure injections. The grouting quality is improved; no casing, tubes etc. needed. - Product type: Self-drilling anchors - Application: Unstable soils (sand, clays, silt, gravel), soft to medium fractured rock - Installation method: Rotary percussion - Function: Used as drilling rod with sacrificial drill bit - Grouting: Controlled pressure injections after flushing (air or water) - Advantages: Improved grouting quality, no casing or tubes required
