Self Drilling Soil and Rock Nails

Our Self Drilling Soil and Rock Nails (SRN) consist of a self-drilling hollow bar with a rolled continuous thread as load-bearing element embedded within a grout body.

SRNs are typically grouted along their entire length. In geotechnical engineering, they are used to stabilise natural or artificial slopes or to support structures e.g. retaining walls. To further stabilise the surface of the slope or rock, various support systems e.g. flexible reinforcing meshes or geotextiles may be installed that are held in place by the head plates of the nails.
