Rock Bolts

Rock Bolts

Rock bolts connect areas of unstable rock outside the rock face to stable rock.

The bar, nut, couplers, and plates of unique solid Threadbar systems are used to create rock bolts.

They are fully-bonded passive installations, as opposed to ground anchors.

The most effective way to transfer weight and maintain the smallest diameter holes is with solid steel Threadbars, which also saves time and money.

Characteristics

A distinctive Threadbar’s continuous thread allows for cutting and coupling at any location.
Threadbar and accessory systems with galvanised or epoxy coatings are offered for installations in challenging ground conditions.
For further corrosion protection, Double Corrosion Protection (DCP) is offered.
When installing threadbars and accessories in challenging ground conditions, galvanised or epoxy coated systems are an option. Double Corrosion Protection (DCP) is also an option for the highest levels of corrosion protection.

Rock bolts are used in:

Ground support
Rock stabilization
Anchorages in rock
Rock and soil

How rock bolts work

Rock normally allows for an open hole to be drilled without any danger of collapsing unless it has been substantially worn.

When bonding unstable rock to stable areas outside the rockface, special Threadbar is employed to provide both tensile and shear loading capacity.

Rock bolts can be placed into considerably smaller holes than soil nails or ground anchors, saving time and money, because rock offers a stronger binding than soil.
