Rock Bolts

Rock bolt is a stress or tensioned reinforcement element consisting of a rod, mechanical or grouted anchorage and a plate and nut for stressing by torquing the nut or for retaining tension applied by direct pull. It is also known as active rock anchor.
Rock bolts are manufactured from TMT grade special steel as per IS:8266/76 specifications in various types.

Expansion Shell Type

These bolts use expansion shells and plugs made of cast steel with left hand thread, firmly gripping the rock and the bolt forming anchorage. These are made of two types.

Expansion Shell Type Grouted
Expansion Shell Type Un-grouted

Perfo Type

These anchors are supplied with a perforated shell sleeve, which is filled with mortar and installed in the hole. A deformed steel anchor bar is pushed into the tube, causing mortar to squeeze through perforations and bond to the sides of the drill hole.

Resin Grouted Type

These anchores are champhered conically at one end and are threaded on the other. The conically tapered end is pushed into the resin cartridge placed at the bottom of the drill hole.

Grouted Anchor Bars

These anchors are made of deformed steel bars threaded on one end and placed into the drill holes and grouted with "Rich Mortar" for furm grip.
