The International Geosynthetics Society revived its Educate the Educators program in 2015. The initiative was developed in the early 1990s to educate engineers, regulators, and academics about geosynthetic materials. In the 20+ years since, the geosynthetics had grown enormously—but how to engineer with these materials had not become standard in college engineering curricula. Industry veteran Robert Mackey (S2Li) notes that college is far from the only place we need to look in focusing on education. We can’t ignore the engineers already in the field.
