Correct concrete cover plays an important role in the strength, durability, and compliance of any structural element. When cover is inconsistent, reinforcement can be exposed to moisture and corrosion, which can compromise the long-term performance of the structure. That’s why getting concrete cover right from the start is essential, and why correctly specified concrete spacers are a critical part of reinforced concrete construction.
Manufactured from high-quality cast concrete, Danterr’s concrete spacers, including concrete aspros, are designed to work seamlessly with the surrounding concrete. Their high compressive strength helps maintain reliable reinforcement support, reducing the risk of weak points and supporting long-term performance across civil, commercial, and infrastructure projects.
What is Concrete Spacer?
Concrete spacers are purpose-built blocks placed between the reinforcing steel and the formwork or external surface of the concrete. Their role is simple but important: keep the reinforcement exactly where the engineer intended.
By maintaining correct concrete cover, concrete aspros and concrete spacer with gal tie wire help protect steel reinforcement from exposure, corrosion, and damage. This is especially important in structures that face harsh environments or long design lives. Their contribution is not only structural but also regulatory, they support compliance with AS/NZS 2425:2015 and other engineering standards.
Key Benefits of Concrete Aspros
- Consistent concrete cover: Delivers accurate rebar positioning to ensure structural integrity and code compliance.
- Stable positioning: Minimises steel movement during pouring, reducing the risk of cover loss or voids.
- Durable performance: Manufactured from strong cast concrete, providing long-term reliability even under harsh site conditions.

Applications of Concrete Aspros
Danterr’s concrete spacers are engineered for versatility and are widely used in the following applications:
- Structural walls and columns: Maintains vertical reinforcement alignment
- Foundations and footings: Ensures base layer rebar cover and support
- Precast and in situ concrete: Compatible with both off-site and on-site construction
- Civil and infrastructure projects: Ideal for large-scale, high-load works requiring durability and precision
Wherever accurate reinforcement placement is essential, concrete aspros are a trusted choice.
Installation Guidelines
Correct installation is key to maximising the benefits of concrete spacers. Follow these simple guidelines for best results:
- Place spacers at regular intervals as specified by project drawings
- Ensure each spacer lies flat against the formwork or substrate
- Confirm the rebar is fully supported and not sagging before concrete placement
- Take care during pouring and vibration to avoid dislodging spacers
