Multi Strand Ground Anchors

A number of stranded cables are assembled to form cohesive anchors complying with the engineers requirements (for either temporary or permanent anchoring requirements).

Product types:
Expansion Shells

Expansion Shells

The unique 3-leaf expansion unit has exclusive features that ensure positive anchorage under the most arduous conditions. The expansion unit, which is available as a 'bail type' unit, is a 3-leafed mechanical anchor which conforms to the hole diameter. This feature ensures a more even load distribution between the anchor and the rock at the anchor point.

Product types:
Thread bar 500

Thread bar 500

No reduction in load capabilities as threads exceed the nominal bar diameter. Robust thread design accepts harsh conditions without affecting threadability. Increased bond strength achieved owing to large surface area of ribs. Continuous thread enables retensioning in the event of ‘scaling’, as well as cutting of the bar at any point.

Product types:

Thread Bar 600 - Dyno Bar

Manufactured from high strength input steel, the Dyno Bar is cold thread rolled into a continuously threaded bar over its entire length. The Dyno Bar system is ideally suited to the construction industry where greater forces are encountered.

Product types:

Thread Bar 950

Based on a continuously threaded bar, the TB 950 is exceptionally versatile and well-proven worldwide. The TB 950 may be cut to finished lengths at the factory or on site and anchorages, nuts or couplers fitted immediately without frustration or delay. Being coarse and robust, the thread is ideally suited for use in the construction industry.

Product types:

Soil Nails

Manufactured from hot-rolled, continuously threaded high tensile bar, manufactured in accordance with ISO 9001 :2000. These products are used in lateral support applications in the civil and construction industries.

Product types:
Duragrout

Duragrout

Duragrout is a medium to fast setting, thixotropic, non shrinking grout, which flows easily and stiffens in-situ. It is designed to achieve good initial strength, gaining further in strength after the initial set has been achieved.

Product types:
Surelock® MECHANICAL ANCHORS

Surelock® Mechanical Anchors

Surelock® mechanical anchors are flexible high-tensile steel strands of specific lengths, anchored inside a drilled hole with an innovative locking-off unit called the ‘Surelock® swivel barrel’ at the collar. The advantage of using this locking-off device is that once the required prestressed load is achieved, the shear ring shears on the barrel into a positive visual indicator with an audible knock.

Product types:
Multi-bulb passive anchor

Multi-bulb passive anchor

The multi-bulb passive anchor is a flexible, high tensile steel strand of a specific length, anchored inside a drilled hole, with an innovative multi-coloured breathing tube system. The advantages of using this breathing tube system in a vertical crater retreat mining operation is that once a round has been blasted, the remaining coloured breather tube indicates the actual depth of the blast.

Product types:
Surelock® Spin Anchors

Surelock® Spin Anchors

Surelock® spin anchors are flexible high tensile steel strands of specific lengths, resin anchored inside a drilled hole with an innovative locking-off unit called the ‘Surelock® swivel barrel’ at the collar. The advantages of utilising this locking-off device is that once the required prestressed load is achieved, the shear ring shears on the barrel into a positive visual indicator with an audible knock.
