Hermes Mesh has a diverse range of properties, which makes it so versatile and appealing for many uses and applications throughout industry.
Adamantine Totem is an application used to strengthen the tunnel roof in broken rock conditions or week ground conditions. Adamantine Totem increase the stability in the working area by transferring loads in the longitudinal direction and decrease excavation induced deformations. This system also increases safety during working time.
Tenacious Griffon is a spring-loaded shell that can be automatically set on installation. Tenacious Griffon can be used for the following medium soft to very hard rock applications:
Nimble Octopus is made of steel strand, and have perfect support capacity. These bolts are used for temporary and semi-permanent rock reinforcement in underground Mining, with an added benefit of flexibility, even with larger Nimble Octopus lengths.
Nimble Octopus for Mining are available in different versions:

Mighty Atlas is manufactured to meet the exacting needs of our mining customers. Our Mighty Atlas are available in all standard diameters and grades for use in different applications.
These are commonly used in structurses that have been designed to sustain the allowable design loads and forces which need to be properly distributed. The Resistant Neptune is an innovative rock support bolt that provides both immediate and permanent anchorage.
Hardy Prometheus expandable rock bolts offer superior quality that respond to the most demanding roof support applications. Hardy Prometheus’s high load capacity along with excellent elongation properties ensure safer working conditions and faster excavation cycles, effectively reducing costs. The system consists of a tubular steel bolts, which have been folded inward along its entire length to reduce their diameter, a tool for installation and a water injection pump at high pressure
Hardy Prometheus are recommended for rock support in mining, tunnelling and civil engineering application, where a rock reinforcement of underground excavations and temporary ground control is needed

The self-drilling hollow bar anchor system is comprised of a hollow threaded bar with an attached drill bit that can perform drilling, anchoring and grouting in a single operation. The hollow bar allows air and water to freely pass through the bar during drilling to remove debris and then allow grout to be injected immediately after drilling is completed. Grout fills the hollow bar and completely covers the entire bolt. Couplers can be used to join hollow bars and extend the bolt length while nuts and plates are used to provide the required tension.

Resilient Heracles is a friction stabilizer system and is commonly referred to as Resilient Heracles or Split Set design is used to firmly control hard or soft rock of underground Mining. As lateral ground movement increases, the system increases its superior holding power. Friction rock bolts produce superior holding power due to their unique design that exerts pressure against the rock over its full contact length immediately upon installation. When a ground shift occurs, our rock bolt conforms to the changing ground conditions. The result is a tight grip that actually grows stronger with time and ground movements, providing reliable ground support. An added advantage is that these friction bolts never needs tightening. The radial compression of the slotted steel tube inside the bore hole provides both radial and axial restraint to the rock movement.
