Abstract

A void form is composed of molded pulp and includes bottom-facing openings. Fresh concrete placed on top of a substrate material covering the void form structure is formed with a void space underneath that allows soil to expand.

Abstract

A device and method for the creation of a water proof component void form unit to create space between concrete structures and expansive soil for the passage of utility conduit lines is described. The unit includes a plurality of panels interlocked with one or more connectors and supports that pass internally through flutes within the panel members. The void space is formed from a singular panel that is scored along a score line. The score line passes only through an upper surface. The panel member is folded about the lower surface at the score line to form the void space. The panels are located in a trench and configured to define a void space underground for the passage of the utility conduit lines. The unit is configured to resist soil expansive forces so as to protect the placement and integrity of the utility conduit lines.

Abstract

A device and method for the creation of a water proof component void form unit to create space between concrete structures and expansive soil for the passage of plumbing lines, electrical lines and other utility conduit lines is described. The unit includes a plurality of panels interlocked with one or more connectors. The panels are aligned opposite one another and are configured to abut one another to create a route. The panels are located in a trench and configured to define a void space underground for the passage of the utility conduit lines. A top cap overlays across the panels. Utility conduit lines are routed within the void space and adjusted according to needs. The unit is configured to resist soil expansive forces so as to protect the placement and integrity of the utility conduit lines.

Abstract

The present application includes a void form unit for creating a void space between concrete structures and expansive soil. The unit includes a cellular structure surrounded by a paper based shell. The cellular structure is impervious to moisture. Together the cellular structure and the shell make a singular rigid member. The rigid member is configured to temporarily support concrete and gradually increase in flexure so as to flex with the movement of the expansive soil. The shell is configured to weaken over time from the regulated absorption of moisture. The flexure of the cellular structure configured to increase with the deterioration of the shell.
