The Arch-lock™ system is a completely different way to construct arches. Overpasses, tunnels, storage sheds, and dozens of other structures can be created in a very short period of time using our zipper truck system. With it, 1.5m of arch can be constructed every 5 minutes! Arches can also be constructed using a counterweight system that doesn't require one to set foot underneath the arch during construction, meaning the arch can be used to cross sensitive waterways or just thin air.

Rod-Lock™ is a composite system 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..
