Overview
Concrete spacers are essential construction components used to maintain the correct spacing between reinforcement bars (rebar) and the formwork. They ensure proper concrete coverage, improving durability and structural integrity.
Why Use Concrete Spacers?
- Ensures Proper Concrete Cover – Protects reinforcement from corrosion.
- Enhances Structural Strength – Provides uniform reinforcement placement.
- Increases Durability – Prevents exposure to environmental elements.
- Supports Heavy Loads – Designed to withstand high pressure.
Common Uses
- Slabs & Columns – Ensures uniform concrete coverage.
- Bridges & Tunnels – Used in large-scale infrastructure projects.
- Foundations & Walls – Provides proper rebar positioning.

Installation Steps
- Select the Right Size – Based on required concrete cover.
- Place Spacers Properly – Distribute them evenly under rebars.
- Secure Positioning – Ensure they remain fixed during pouring.
- Check Alignment – Verify uniform spacing for consistency.
Case Studies
- High-Rise Buildings – Used to reinforce stability in skyscrapers.
- Industrial Facilities – Ensures long-term durability under heavy loads.
Maintenance
- Store in a Dry Area – Protect from moisture before use.
- Inspect for Cracks – Replace damaged spacers before installation.
