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.
Today’s 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.
• ISIS Canada developed...
