Types of Form Liners
There are several different types of form liners, which vary based on the application. Single-use form liners are usually made of styrene plastic and are normally discarded after the first use. Multi-use form liners are usually made of ABS plastic and range in number of uses from 2 to 10 or more. Multiple-reuse form liners are usually made of polyurethane, a heavy rubber material known for its reusability and used frequently by departments of transportation on sound walls, bridges and other applications. Other form liner materials used can include polystyrene foam, fiberglass, and even aluminum-- styrene plastic, ABS plastic, and urethane are considered to be the industry standard, and are most often specified in plans by architects and engineers.
The form liners are attached to forms and concrete is placed against the liner. The liner pattern is transferred into the wet concrete. After the concrete has cured, the liner is stripped and the unique sculpture is exposed.

“Freedom is the essence of this faith. It has for its object simply to make men good and wise. Its institutions then should be as flexible as the wants of men. That form out of which the life and suitableness have departed should be as worthless in its eyes as the dead leaves that are falling around us.”
—Ralph Waldo Emerson (1803–1882)
