Rod-Lock™ system

The Rod-Lock™ system is composed of galvanized steel rods, locking anchors and solid, post tensioned concrete units made with the proprietary interlocking system developed exclusively by Lock-Block Ltd.

Steel rods are threaded through the keys and locked in place with anchors at every level. Rods can also be extended into the ground or concrete base and grouted into place to ensure maximum stability, while positive connections between each concrete base increase lateral rigidity of the overall wall.


The Rod-Lock™ system enables quick assembly, saving time and money.  It is perfect for industrial settings, such as commercial and municipal material dumps, recycling yards, garbage transfer stations, mines, or anywhere else retaining walls are subjected to dynamic loads. Post-tensioned concrete units also make the Rod-Lock™ system ideal for rectangular tunnels, box culverts, and bunkers.

  • Assembles quickly and easily.
  • No cracking and separating.
  • Minimal loader bucket interference (due to smooth-faced concrete units).
