Geo-Believability®: Bringing Realism to Your Project

Bringing Realism to a Project

Creating a realistic golf course water feature the way nature intended is no easy task. Recreating a stream the way it flows and bends in nature requires artistic ability and a disciplined approach to engineering and accurate construction management. The same can be said when recreating a rugged mountain pass with artificial rockwork at a theme park or themed resort. Creating natural habitats that bring a sense of realism to the project is called Geo-Believability®.

The term “Geo-Believability®” was coined by the artisans at Outside the Lines. They studied and learned how to design and create rockwork and water features to be as geologically accurate as possible.
