In 1997, Dywidag-Systems International (DSI) contacted BP Automation to develop a threaded fibreglass rebar system. In 1999, the company developed threaded fibreglass manufacturing equipment. In 2000, BP Composites was formed to supply the mining industry with fibreglass rebar and rock bolts. Production Brow, Penobsquis, New Brunswick
In 1995 the Canadian Government formed the Intelligent Sensing for Innovative Structures (ISIS) to find a solution to the crumbling infrastructure of North America. Consisting of 14 Universities and 22 Researchers with a 15 year mandate to publish the CSA code Spalling on bridge girder
Romans are the pioneers of the concrete revolution. Their structures have lasted close to 2000 years. Pantheon, Rome; Constructed ~126AD; worlds largest unreinforced dome.
Reinforced Concrete with Steel Rebar is the cause of the failing infrastructure Steel rebar has been used since the early 1900’s Steel expands 10x in volume when it rusts, and causes concrete to crack and fail Iron Iron Oxide

In 2001, ISIS Canada published guidelines for building with GFRP In 2006, ISIS Canada developed a Product Specification Manual for GFRP reinforcement for civil application.
In 2007, ISIS encouraged BP Composites to develop a family of GFRP rebar suitable for civil infrastructure.
