Concrete Spacers

Concrete Spacer Selection Guide

Concrete spacers help prevent reinforcement from resting directly against the formwork and support the required concrete cover throughout installation. Foundations, slabs, walls, columns, tunnels, bored piles and other reinforced-concrete applications may require different spacer geometries and sizes. Selection should therefore be based on project cover requirements and the reinforcement arrangement rather than price alone.

Concrete Spacer Types

Fiber-Added Wire and Clip Spacers

The category includes fiber-added wire concrete spacers and fiber-added clip spacers. The appropriate type should be selected according to reinforcement diameter, application direction and required cover.

Linear, Bar and Profile-Type Spacers

Linear-contact, solid square-bar, solid triangular-bar and profile-type fiber-added spacers are available for different support and placement requirements. A continuous-contact application and a point-support application may require different spacer geometries.

Multi-Size and Diaphragm-Type Spacers

multi-size concrete spacers and diaphragm-type products are also listed. The actual cover dimension should always follow the project requirement.

Heavy-Duty Concrete Spacers

Flat-base heavy-duty products and heavy-load concrete spacers are available for applications with higher support requirements. Reinforcement weight and placement conditions should be considered before selection.

Bored-Pile, Tunnel and Special Application Types

bored-pile fiber-added spacers, tunnel types and snake-type products provide options for specific reinforcement geometries and applications.

Tie-Rod Plugs and Pipes

The category also contains fiber-added tie-rod plugs, gasketed tie-rod plugs and tie-rod pipes. For related formwork connections, see Scaffolding and Formwork Components.

Concrete Spacers vs Plastic Spacers

Concrete/fiber-added spacers and plastic spacers can serve a similar cover-control purpose, but their materials, geometries and application methods differ. Selection should reflect the project specification, reinforcement layout and required cover. See Plastic Spacers for the alternative product group.

What Should You Consider When Choosing Concrete Spacers?

• Concrete cover: select a spacer that matches the cover specified by the project.
• Application direction: horizontal slabs and foundations may use different products from walls and columns.
• Reinforcement layout: bar diameter, spacing and cage geometry can affect the suitable spacer type.
• Load requirement: heavy reinforcement arrangements may require heavy-duty spacer products.
• Fixing method: wire, clip and other attachment geometries should match the application.
• Quantity: total requirements should be calculated from the project layout and spacer placement plan.

Concrete Spacer Prices

Concrete spacer prices can vary according to spacer type, cover dimension, material and geometry, load class, pack quantity and order volume. Wire, clip, linear, multi-size, bored-pile and heavy-duty products are intended for different applications, so unit price alone may not provide a useful comparison.

Frequently Asked Questions

What is the purpose of a concrete spacer?

It helps hold reinforcement away from the formwork surface and maintain the concrete cover specified by the project.

How is concrete spacer size selected?

The required cover comes from the project specification. Reinforcement layout and application direction should also be considered when selecting spacer geometry.

What is a fiber-added concrete spacer?

It is a concrete-based spacer product manufactured with fiber reinforcement. The category includes wire, clip, linear, bar, profile, diaphragm, bored-pile, tunnel and other special types.

Are concrete and plastic spacers the same?

No. They may support a similar concrete-cover function, but their materials and geometries differ. The appropriate type depends on the project and application.

When is a heavy-duty spacer used?

Heavy-duty spacer products can be considered where reinforcement arrangements impose higher support requirements. Final selection should follow the project and application conditions.

How many concrete spacers are required?

There is no single fixed quantity for every project. Reinforcement spacing, spacer type, cover dimension, structural geometry and placement plan determine the total requirement.
