Deslauriers Box Voids can be used to create a void area under load bearing beams or slabs for soil expansion.
Box void forms hold up the weight of fresh concrete long enough for the concrete to cure and support itself on slabs, piers or beams. Since it’s a paper product, it absorbs the moisture of the surrounding soil and concrete and its supportive strength gradually diminishes over time.
Box Voids are easily assembled on site with no special tools. They come in 4’ length, 12” wide, 4” or 6” high. They are made from double faced corrugated fiberboard, wax coated and laminated. Box Voids are a closed cell product, hence compressible and high compression resistance.

Box Voids are a versatile and economical means of forming concrete slabs allowing space for soil expansion under load-bearing beams or slabs. Your concrete slabs will be intact and durable even in poor soil conditions.
Product Description
Box Voids are a versatile and economical means of forming concrete slabs protects and provides a space for soil expansion under load-bearing beams or slabs. These one-piece units are crafted from double-faced corrugated fiberboard, which is wax coated and laminated to ensure durability and longevity. The self-locking design eliminates the need for stapling, taping, or banding, while the closed ends prevent any leakage of concrete during the forming process. Available in sizes 12” wide by 4” and 6” deep by 4’-0 lengths, Box Voids are suitable for a wide range of construction projects, offering a reliable solution for creating void spaces.
Uses
Box void forms for load bearing beams or slabs, to allow for expansive soils. For concrete slabs, piers or beams. For residential, commercial and industrial projects. By providing a space for expansion, Box Voids ensures stability and durability of the concrete structure. So it’s a must have in any project where soil movement can damage the concrete.
Applications and Benefits
Box Voids are ideal for forming concrete slabs protects piers or beams especially in scenarios where space for expansive soils is crucial. They effectively protect concrete slabs and below-grade utilities from the costly damage caused by uplift pressures due to soil expansion. By creating a void area under load-bearing beams or slabs, Box Voids ensure the stability and durability of the concrete structure. Their versatility makes them suitable for various construction projects, including residential, commercial, and industrial applications, providing a robust solution for managing soil movement.
Box Void Forms
Void forms are a critical component in concrete construction, providing a space for expansion and protecting the structure from uplift forces. There are several types of void forms available, each with its own characteristics and uses. Knowing the different types of void forms will help you choose the right one for your project.
Solid Void Form
Solid void form is an expanded polystyrene (EPS) product, available in strips and sheets. Protects the structure from uplift forces from frost or soil swelling. Used beneath grade beams, slabs, pile caps and other applications. Solid void form is made from various material grade options, GWF 5 (Type 0), GWF 10 (Type 1), GWF 13 (Type 2). Material grade options to choose from to fit your project requirements.
Frost Cushion
Frost cushion is a profiled strip or sheet of expanded polystyrene, used beneath grade beams to compensate for swell caused by frost or moisture in the soil. The profiled shape will deform under uplift forces at a lower stress than solid void form. Frost cushion is made from GWF 10 (Type 1 insulation) and can be made in other insulation grades. Ideal for projects in cold climates where frost heave is a concern.
Collapsible Void Form
Collapsible expanded polystyrene (EPS) void form is designed to support concrete structural slabs during pour. Once construction is complete this void form can collapse under ground swell uplift forces such as frost heaving or expansive soil. EPS Molder’s collapsible void form is made from GWF 15 (Type 2 insulation). This design allows the void form to provide support during construction and adapt to changing soil conditions over time.
Materials and Construction
Constructed from double-faced corrugated fiberboard, Box Voids are wax coated and laminated to enhance their durability and longevity. This sturdy, moisture-absorbent material is ideal for concrete forming applications. The self-locking design and closed ends of Box Voids prevent concrete leakage during the forming process, ensuring a secure and efficient assembly. Additionally, the use of double-faced corrugated fiberboard provides excellent lateral stability, eliminating the need for side bracing and making the installation process straightforward and reliable.
Installation and Use
Box Voids are designed for easy on-site assembly, requiring only one person to set up without the need for special tools. They can be quickly and efficiently installed, holding up the weight of fresh concrete long enough for it to cure and support itself on piers or beams. Over time, the supportive strength of Box Voids gradually diminishes as they absorb moisture from the surrounding soil and concrete, allowing for the creation of a void area under load-bearing beams or slabs. This feature ensures that the concrete structure remains stable and durable, even as the soil conditions change.
Advantages and Considerations
The use of Box Voids offers numerous advantages, including providing a space for expansion, protecting concrete slabs and below-grade utilities from costly damage, and ease of installation. They are a cost-effective solution for forming concrete slabs protects, piers, or beams. However, it is crucial to consider the material grade options and the specific requirements of the construction project to ensure the correct selection of Box Voids. Additionally, the surrounding soil conditions and the potential for expansion should be taken into account to maximize the effectiveness and longevity of the concrete structure.
