MAI® Self Drilling Soil & Rock Nail
Soil Nailing is a technique used to reinforce and strengthen existing ground conditions of slopes and battered cuttings. The MAI Soil & Rock Nail is used in accordance with DIN 21521 and offers a rapid and economical alternative to the traditional  methods.
Some of the many advantages are listed below:
  • It is in particular suitable for very difficult and unstable ground conditions, such as unconsolidated sands, gravel’s or broken and fractured rock formations.
    The installation method is for all ground conditions similar.
  • Being a Self Drilling Nailing System, there is no requirement for a primary drilling system, drilling and installation are performed simultaneously.
  • Therefore the potential danger of collapsing boreholes is avoided.
  • Often the only solution for restricted access conditions and undeveloped regions.
  • The additional feature of simultaneously drilling and grouting during installation allows loose ground conditions to be consolidated at the same time.
