ReidBar™ Soil & Rock Anchoring System

Find a Local Trade Centre

The ReidBar™ Soil & Rock Anchoring System provides a robust, fully engineered method for stabilising soil and rock, combining continuously threaded ReidBar™ 500E reinforcement with specialised fittings for long‑term anchor performance. Designed for both passive (fully grouted) and active (tensioned) anchors, the system offers dependable load transfer using domed base plates and spherical washers that accommodate up to 20° of bar misalignment.

ReidBar’s ductility and strain‑hardening characteristics enable safe anchoring under shear or tensile overload caused by ground movement. Spherical washers ensure correct nut seating even on uneven faces, while domed plates distribute anchor forces effectively into surrounding material. Compatible nuts, couplers, and fittings complete a versatile anchoring system widely used in retaining structures, slope stabilisation, excavation support, and infrastructure works.

Fully engineered soil & rock anchoring system Combines threaded ReidBar™, nuts, plates, and spherical washers for reliable long‑term stabilisation.
Accommodates up to 20° bar misalignment Spherical washers and domed plates work together to support imperfect drilling alignment.
High‑capacity 500E threaded bar enables tensioned or passive anchoring Suitable for both load‑locked anchors and fully grouted nails.
Long-term durability with galvanised hardware options Domed plates and spherical washers are supplied in hot‑dip galvanised steel for corrosion resistance.
Safe under ground movement ReidBar’s ductility and strain‑hardening characteristics prevent brittle failure during soil/rock deformation.
Efficient installation and adjustable tensioning Threaded bar allows the anchor to be tensioned, released, and re‑tensioned as required.
Rugged thread resists damage Ideal for harsh drilling and handling environments.
Versatile system for multiple applications Used for slope stabilisation, retaining structures, tiebacks, foundations, and tunnelling.
