Introduction

4in Depth Voids are a versatile and economical way to form concrete slabs, protects against expensive damage caused by uplift pressures produced by expansion. Void forms create a void area under load bearing beams or slabs for expansion and lateral stability to the concrete structure.

Made from double faced corrugated fiberboard, wax coated and laminated, these box voids are a durable and reliable solution for concrete construction. Voids absorbs the moisture of the surrounding soil and concrete and its supportive strength diminishes but will hold up the weight of fresh concrete long enough for it to cure and support itself on piers or beams.

Box voids can be assembled on site in minutes with no special tools. High vertical strength of 1200 pounds per Sq. Ft. Box voids provides excellent support and stability for slabs, reduces the risk of expensive damage and ensures a solid structure.

Using box voids can reduce the amount of concrete needed for a project and minimize soil excavation, makes it an economical way to form slabs. Box voids can be used for concrete slab protection, grade beams, grade utilities and available in 4’ length, 12” wide, 4” or 6” high.

Deslauriers box voids is a popular choice among contractors and builders because of its ease of use, durability and effectiveness in protecting concrete structures from expansion. By creating a void area under load bearing beams or slabs, box voids prevents uplift pressures produced by expansive soils and ensures a solid structure.

Box Voids are a type of void forms used in concrete foundation construction to create space between the concrete foundation and expanding soil. Box void forms create void areas under beams or slabs for expansion. They hold up freshly poured concrete until it has enough strength to support itself on slabs, piers or beams. Made from double faced corrugated fiberboard, these carton forms have high strength and durability. The fiberboard is laminated for long life and reliability in harsh construction conditions. It’s a must have for expansion and concrete protection.

Types

Voids are a versatile and economical way to form slabs and comes in different types to suit different construction needs. Here are some of the most common types of voids:

1. Standard: These are the most common voids, made from corrugated fiberboard and laminated for durability. Available in 4” depth, 12” width, 48” length. Standard box voids are for general slab applications where expansion is a concern.

2. High-Strength: For heavy duty applications, these voids has higher weight capacity and increased vertical strength. Under load beams or slabs that requires additional support. Robust construction can withstand the pressure of concrete and provide the necessary void space for soil expansion.

3. Degradable: Made from materials that can degrade over time, such as molded paper or corrugated paper, these voids is suitable for construction sites with sufficient water supply to degrade the material before soil expansion occurs. Degradable box voids is perfect for areas with significant soil movement, creates a void space that accommodates expansion without compromising the slab.

4. Collapsible: These box voids is engineered to collapse under the pressure of soil, provides a space between the foundation and the soil. Strong enough to withstand the pressure of fresh concrete but weak enough to yield to the pressure of expanding soil. Collapsible box voids is ideal for projects in areas with highly soil, ensures the concrete structure remains solid and undamaged.

Construction and Materials

Voids are made from high quality materials to meet the demands of concrete construction. These forms are for slabs allowing space for expansion, ensuring the structural integrity of the concrete during the curing process. Corrugated fiberboard provides good resistance to moisture and compression for slab forming. Wax coating and lamination makes it strong and durable to hold the weight of concrete. Available in 4” depth, 12” width, 48” length.

Applications and Benefits

Voids are used in many applications in concrete construction, especially in creating voids under beams or slabs. Box void forms are versatile and can be easily assembled on-site, making them an efficient solution for various construction needs, and they are long enough for the concrete to adequately sustain itself during the curing process. This allows space for expansion which is necessary in areas with expansive soil. By using Voids, construction projects can reduce soil excavation and concrete quantity, saving cost and time. Voids also adds stability to slabs, a must have in protecting concrete structures from uplift pressure and damage. Easy to assemble on site with no special tools.

Installation and Considerations

Voids are quickly and easily assembled with minimal labor and expertise. They can be assembled on site with no stapling, taping or banding required. However, please consider the soil and concrete conditions around the Voids. The weight of concrete and expansion must be taken into account to ensure the Voids can support. Over time the supporting strength of Voids will decrease as they absorb moisture from the soil and concrete, so proper installation and consideration of environmental factors is important.

FAQs

1. What is a box void, and how is it used in concrete construction? A box void is a sacrificial formwork member used to create a space between the concrete foundation and expansive soil. It provides temporary support for concrete until it achieves adequate strength to support its loads. This helps in forming slabs and protecting them from expansion pressure.

2. What are the benefits of using voids in concrete construction? Box voids offer several benefits, including reducing soil excavation, decreasing the quantity of concrete needed, and creating a more stable slab. They also absorb expanding soil volume and reduce the risk of damage caused by expansion, ensuring the longevity and durability of the concrete structure.3. What is the typical space between a foundation and underlying expansive soil to install box voids? The distance between the concrete foundation and soil underneath is 5 cm to 60 cm depending on the soil uplift. This space allows for soil without exerting pressure on the slab.

3. What type of box void is suitable for use under a slab? Degradable voids are the best for use under a slab, as they can degrade over time and provide a space between the foundation and the soil. This degradation process ensures the void space is maintained, accommodating expansion and protecting the slab.

4. How do box voids protect slabs and soil? Voids protect slabs and surrounding soil by providing a space between the foundation and expansive soil, reducing the risk of damage caused by expansion. They absorb the expanding soil volume, which helps in maintaining the stability of the slab and reducing the quantity of concrete required for the project. This makes voids a must have in areas with expansive soil, ensuring the integrity and durability of concrete structures.

Void forms are a versatile and efficient solution for creating voids under load beams or slabs, allowing space for expansion. Made from corrugated fiberboard, they are strong and durable for various concrete construction applications. Easy to install and many benefits, box void are a must have in concrete construction, especially in areas with expansive soil. Get void forms and have a stable, efficient and cost effective way to manage expansion and your concrete projects.
