Without reliable formwork accessories, the pressure exerted by wet concrete can lead to blowouts, misalignments, or bulges.
Key types of formwork accessories include:
- Form Ties: These hold opposite sides of a formwork system together, limiting spreading under the lateral pressure of fresh concrete. Options like snap-tie wedges and cone ties are available for different forming systems.
- Brackets: Used to support formwork components, create corners, or attach bracing.
- Chamfers: Small strips, often made of plastic or wood, inserted into the formwork to create beveled or rounded edges on the finished concrete.
- Coil Products: Often used with form ties and other hardware, these threaded components allow for assembly and disassembly of formwork systems, providing versatility and strength.
The Role of Reinforcement Supports
If rebar is the skeleton of a concrete structure, then reinforcement supports are what hold that skeleton in place. Their primary function is to help ensure that steel reinforcement maintains its position and proper concrete cover before and during the concrete pour.
We, at Hercules Rebar Chairs, focus on this field. Our robust rebar chairs and concrete supports are designed to perform this vital role. Without adequate support, rebar can sag, shift, or get pushed down during the pour. This can lead to insufficient concrete cover, exposing the steel to moisture and air over time.
Common types of reinforcement supports include:
- Rebar Chairs: These individual supports lift the rebar off the subgrade or formwork. Our red Hercules rebar chairs are easily identifiable on job sites across the USA, helping keep the rebar at the specified height.
- Bolsters: Longer, continuous supports used to hold multiple parallel bars at a consistent height over a larger area.
- Spacers: A general term for various devices, often made of plastic or concrete, used to maintain the distance between layers of rebar or between rebar and the formwork.
We offer specialized products like our 2-Bar Footer Stand which is designed for supporting two bars in footers, helping provide stability and consistent placement.

Frequently Asked Questions about Concrete Accessories
We often hear common questions about concrete construction accessories from builders and contractors. Here are some of the frequent inquiries and our answers.
How do I choose the right rebar support for my project?
Choosing the correct rebar support is important for the performance of your concrete. Consider the following:
- Slab Thickness: The rebar chair must lift the rebar to help achieve the specified concrete cover.
- Rebar Size: The diameter of the rebar influences the type and strength of the support needed.
- Load Requirements: Consider the weight of the rebar mat itself, as well as any foot traffic or light equipment that might be on the rebar cage before the pour.
- Base Material (Soil vs. Vapor Barrier): If pouring directly on soil, a wider base on the chair can help reduce sinking. If a vapor barrier is present, chairs should be compatible with it.
For more general background on how rebar works within concrete, you can reference this overview of rebar in reinforced concrete.
What is the purpose of a form tie?
The purpose of a form tie is to hold concrete formwork together against the lateral pressure of fresh concrete, helping ensure the wall or structure is the intended thickness. As wet concrete is poured, it exerts hydrostatic pressure on the formwork. Form ties pass through the formwork and are secured on the outside, creating a system that helps maintain the form’s dimensions.
Can concrete accessories be reused?
The reusability of concrete construction accessories depends on the specific accessory type and its design.
- Reusable: Many formwork components, such as steel form panels, strongbacks, walers, and certain types of clamps and brackets, are designed for multiple uses, provided they are cleaned, maintained, and inspected for damage.
- Single-Use: Items like most form ties (for example, snap ties), embedded lifting inserts, and many types of rebar chairs are typically designed for single use. Once concrete sets around them, they become part of the structure or are no longer suitable for reuse.
- Limited Reuse: Some accessories might have limited reuse potential, often requiring careful extraction and inspection before they are used again.
Always consult the manufacturer’s guidelines and applicable safety standards to determine if an accessory can be reused safely and effectively.
