Romans are the pioneers of the concrete revolution. Their structures have lasted close to 2000 years. In 1995, Intelligent Sensing for Innovative Structures (ISIS) was formed by the Federal Government to investigate the crumbling infrastructure of North America. Todays Steel-reinforced concrete will begin to deteriorate after 10 to 15 years and will generally require major repairs after 25 years.

In 1997, Dywidag-Systems International contacted BP Automation/Brandstrom Engineering Ltd. to develop a threaded fibreglass rebar system. In 1999, the company developed threaded fibreglass manufacturing equipment. In 2000, BP Composites Ltd. was formed to supply DSI and the mining industry with fibreglass rebar and rock bolts.
In 2006, ISIS Canada developed a Product Specification Manual for GFRP reinforcement for civil application. BP Composites Ltd. adjusted and expanded their GFRP process to create a family of rebar sizes suitable for concrete reinforcement.
