How it started
History
The IGGA was first incorporated in Lakewood, California, in June 1972. In 1995, the IGGA affiliated with the American Concrete Pavement Association (ACPA) to represent its newly formed CPR Division, to serve as a technical resource and industry representative in the marketing of grooving, grinding, and CPR/CPP to Departments of Transportation, municipalities, and engineers worldwide.
