Abstract:
A form void for providing a space between a poured concrete structure and an underlying expansive soil is formed of three sheets of corrugated paper for shipping in a flat "knock-down" configuration and is erected at the construction site simply by inserting one panel into a groove between two other panels. The upper surface is comprised of three panel thicknesses, and the outer support panels are reinforced by a pair of internal support panels. The cross-sectional shape may be trapezoidal, rectangular, symmetric or non-symmetric, or have a sloped top.
