What is Geofoam?

Landscape architects say Geofoam, the lightweight, cost-effective, environmentally safe and recyclable fill material a key to creativity. Giant blocks of Geofoam will transform flat land into a hilly landscape at Maggie Daley Park. “With Maggie Daley Park, you’re going to have hills. The park will offer these beautiful vistas of Lake Michigan, which it never had there,” said Bob O’Neill, president of the Grant Park Conservancy.
