Void Systems

To reduce the risk of structural damage from expansive soil, several void systems are available to protect your project. From beams to piers to slabs, VoidForm has perfected the balance between initial product strength and subsequent collapsibility once the concrete becomes self-supporting. Non-degradable utility isolation systems protect below-grade plumbing and conduit from damaging soil.

Void Forms

Paper and Plastic Substrates

When properly protected from premature moisture absorption, paper-based void forms offer the greatest loss of strength to ensure complete structural breakdown after the concrete is placed. On the other hand, when excessive moisture prevents proper placement of the paper-based void form, flexible plastic void forms that are impervious to water are the best option.
