Ongoing research.

Located on Mitchell Island in Vancouver, Lock-Block Ltd. invented the Lock-Block™ system and has developed and pushed the envelope since inception. Our development department continues to move boundaries in many areas. We are constantly improving our concrete recycling technology and creating new structures using both the Arch-Lock™ and Dome-Lock™ systems.

Lock-Block Ltd. has a dedicated research department with a 3d printer that is used to make any new product a customer desires. We have 1:25 scale models of every product in stock for use. Engineers and contractors are able to visit our office to make a physical mock-up in order to get a hands-on feel of what will work for their projects at the early design phase, saving time and money.
