The Advantages and Disadvantages of Rock Anchor Drilling

Our drilling contractors believe in full transparency with our customers. This is why we want you to know both the advantages and disadvantages that come with rock anchor installation and use. They include:


  • The drilling contractor can grout and pre-stress the drilling rock anchor bolts within the same day to save time.
  • Less drilling is necessary because it's a no bond zone. You also need less grout since the hole you drill is smaller.
  • You'll get an oversized drill hole that provides great grout coverage.
  • The install pre-stresses the anchor bolt, and this reduces grout cracking.


  • The maximum load the ultimate tensile steel capacity bolt can handle with a 2:1 safety factor is 1,241 Mpa.
  • Rocks can get in the way and interfere with the bonding process.
  • Water pressure can negatively impact your anchor's ability to hold.
