Self Drilling Anchors - Soil Nails - Rock Bolts
Soil Nailing bolts usually involves the insertion of reinforcement bars (Hollow/solid) into the exposed slope followed by grouting, placement of a wire mesh and shotcreting before the testing and locking off of the nail through stressing jacks. Hollow soil nail bars can also be self-drilling thus acting as drilling rods with expendable drill bits. Soil nails are cost effective for stable soils where water pressure is not an issue and for excavations where space is a constraint.
They may be bonded along their entire length by cement grouting or anchored at various points at the base of the hole using chemical resin or a mechanical anchorage. Rock bolts transfer load from the unstable exterior, to the confined (and much stronger) interior of the rock mass.

JB self drilling anchors (SDA)
When ground conditions are unstable, water-bearing, or fractured, traditional anchoring methods often fail. JB Self-Drilling Anchors (SDA) are engineered to deliver reliable ground support in difficult soil and rock formations – without the need for pre-drilling.
Designed and manufactured by JB Engineering, our SDA system combines drilling, anchoring, and grouting into one efficient operation. This reduces installation time, improves site safety, and ensures strong load-bearing performance in demanding environments.
JB Soil Nails
Unstable slopes, vertical excavations, and loose soil formations can pose serious structural and safety risks. JB Soil Nails are designed to reinforce soil mass by creating a composite, stable ground structure that resists displacement and collapse.
Manufactured by Rebar Couplers India Private Limited (JB Engineering) – an ISO 9001:14001:45001 Certified Company – our soil nailing systems are engineered for strength, durability, and dependable load performance under challenging site conditions.
JB rock bolts
A Rock Bolt is a long anchor bolt used to stabilize rock in tunnels, rock slopes, and underground excavations. It transfers load from the unstable outer zone of the rock mass to the stronger, more stable interior.
Manufactured by JB Engineering (Rebar Couplers India Private Limited) – an ISO 9001:2015, ISO 14001:2015 & ISO 45001:2018 certified company – JB Rock Bolts are engineered for strength, structural reliability, and long-term performance in demanding geotechnical and mining environments.
SN and rock bolts and accessories
In underground construction, mining, and slope engineering, fractured rock and unstable ground can lead to serious structural risks. JB SN Bolts and Rock Bolts are engineered to provide reliable rock anchoring solutions, improve load-bearing capacity, and ensure long-term structural stability.
Designed and manufactured by Rebar Couplers India Private Limited (JB Engineering) – an ISO-certified manufacturer – these reinforcement systems are produced under strict quality control standards to meet the demands of metro rail, hydropower, tunnel, mining, and infrastructure projects.
