JB ROCK BOLT SYSTEM Grouted Rock bolts have been commonly used world- wide in mining and civil engineering applications. The most used grouted Rock bolt is the fully grouted rebar or threaded bar made of steel. Cement or resins are used as grouting agent. The rebar used with resin creates a system commonly used for tensioned rock bolt but the rebar or the threaded bar with cement grout can also be used for un tensioned bolts

JB Engineering Soil Nails JB Engineering Soil Nailing is a technique that can be used either on natural or excavated slopes, where the slope is reinforced by the insertion of tendons. The nails address the slope stability, which are connected in turn to a facing system and provides surficial stability. JB Engineering Offers different types of anchor bars for use in conjunction for rockfall protection and natural hazard mitigation. These are used for numerous applications. JB Engineering Anchor Bars are Available in different Diameters 25mm,32mm, 36mm, 40mm , steel strengths and corrosion protection, as per IS Code 12594-1988, and/ or epoxy coated- as per IS 13620;1993. JB Engineering Make Accessories Like Joint Couplers, Anchor Plates and Anchor Bolts are also available as per Project requirements and ground conditions. The Various Components of JB Engineering Make Soil Nails are: 1. Steel Reinforcing Bars: The solid steel Reinforcement Bars with minimum strength of Grade 500/550, 670/800,950/1050 are the main Components of the soil Nailing System.These are Placed in predrilled drill holes and grouted in place. 2. Centralizers: PVC Centralizers are fixed to the soil nails to ensure that the soil nail iscenter in the drill hole. 3. Nail Head: The Nail head is the threaded end of the soil Nail that protrudes from the wall facing. It is a square shape Steel Structure, which includes Bearing Plates, Nuts.JB RE-BAR Couplers are used to extend the Length as per designs of the Project. This Part of the Structure Provides the soil Nail bearing strength, and Transfer bearing loads from the soil mass to Soil Nail. 4. Hex Nut Washers and Bearing Plates are attached to the soil nails Heads and are used for connecting the soil Nails to the facing. Bearing Plate distributes the force at nail end to temporary shotcrete facing.
