Void Former

Concrete slab void formers are temporary structural inserts used to create controlled empty spaces within poured concrete slabs. These voids allow for the installation of utilities, ducts, pipes, and service systems while reducing overall concrete volume and structural weight. Void formers are a practical solution for modern construction projects that require efficient integration of mechanical, electrical, and plumbing infrastructure.

Manufactured from lightweight yet durable materials, void formers are easy to position before a pour and remain stable during concrete placement. After curing, the formed cavities provide clean, predictable spaces for routing utilities and accommodating future system modifications.

Tengco supplies concrete void formers in multiple material options to suit different project environments, load requirements, and sustainability goals.

Concrete slab void formers are widely used in both residential and large-scale construction projects. In residential construction, they help create pathways for plumbing and electrical systems while reducing slab weight and material usage. In commercial and industrial settings, they are used to form utility corridors, underground service routes, and spaces for mechanical systems that require long-term accessibility.

• Residential slabs requiring integrated plumbing and electrical pathways
• Commercial buildings with embedded mechanical and utility systems
• Industrial facilities requiring underground service access
• Bridge decks and structural slabs where weight reduction is beneficial
• Projects designed for future maintenance and system upgrades

By incorporating void formers into slab design, contractors can improve construction efficiency, reduce material costs, and simplify future building modifications.
