Good concrete construction starts well before the pour. Getting reinforcement into the right position from the outset is what helps a structure perform as intended over time. Cast concrete spacers play a practical role in this process, providing a reliable way to control cover and keep reinforcement where it needs to be during construction.
Danterr’s range of concrete spacers is manufactured from cast concrete to provide dependable reinforcement support on site. Designed to work with the surrounding concrete, these spacers help contractors maintain consistency and accuracy across civil, commercial, and infrastructure projects, even in demanding conditions.
What are Cast Concrete Spacers?
Concrete spacers are reinforcement support components used in reinforced concrete construction to maintain the specified concrete cover by holding steel reinforcement at the correct distance from formwork or the concrete surface. By supporting reinforcement before and during concrete placement, they help reduce movement, improve accuracy, and contribute to the durability and long term performance of structural elements across civil, commercial, and infrastructure projects.

Applications of Cast Concrete Spacers
Cast concrete spacers are designed to support accurate reinforcement placement across a wide range of structural concrete works. Their strength, stability, and compatibility with concrete make them suitable for applications where consistent cover and reliable performance are required throughout the construction process, including:
- Structural walls and columns
- Foundations and footings
- Precast and in situ concrete elements
- Civil and infrastructure construction
Proven Performance in Danterr Projects
Danterr’s cast concrete spacers have been supplied to major infrastructure projects across Australia, supporting large scale civil works delivered under complex technical and logistical conditions.
Ison Road Overpass – The Ison Road Overpass is a major road infrastructure project in Victoria aimed at improving traffic flow and supporting long term transport efficiency. The project involved significant structural and civil construction works delivered within a live road and rail environment. Its delivery reflects the scale and complexity typical of modern transport infrastructure projects.
North East Link Early Works – The North East Link Early Works package forms a critical part of one of Victoria’s largest transport infrastructure programs. This stage focused on enabling works and early construction activities required to support the delivery of the broader project. The scope and scale of the early works highlight the demanding conditions associated with large urban infrastructure developments.

: Frequently Asked Questions:
A concrete spacer is a small yet essential construction component used to maintain the correct spacing between reinforcement bars (rebar) and the formwork in concrete structures. These spacers ensure that the rebar remains in its position within the concrete, providing the necessary cover to protect the rebar from environmental factors like moisture and chemicals that can cause corrosion. Concrete spacers are crucial for ensuring structural integrity, durability, and safety of concrete structures.
Concrete rail spacers provide continuous support along reinforcement runs, helping maintain consistent cover and improving installation efficiency over larger areas.
Choosing the right concrete spacer involves considering several factors:
- Load-Bearing Capacity: Determine the amount of weight the spacer needs to support. For heavy-duty applications, choose spacers with high compressive strength.
- Environmental Conditions: Consider the environment where the spacers will be used. For example, plastic spacers are suitable for areas exposed to moisture, while metal spacers may be better for high-temperature applications.
- Type of Concrete: Different types of concrete (e.g., high-strength, lightweight) may require specific spacers.
- Project Specifications: Ensure the spacers meet the specific requirements of your project, including the required cover depth and the size of the rebar.
Yes. Their continuous rail format reduces the number of spacers required, helping speed up installation while maintaining consistent cover.
Danterr works with contractors and engineers to help select the most suitable concrete spacer type for each application.
Yes. They are commonly used in large concrete pours where consistent reinforcement support is critical.
