What Are Concrete Donuts?

Concrete donuts are the cornerstone of stability and support for a wide range of infrastructure in the civil engineering, mining, and agriculture industries. These circular precast concrete blocks serve as the foundation for structures such as fuel tanks, sea containers, building dongas, transportable houses, and more.

Crafted with precision in a controlled factory setting, concrete donuts guarantee the highest level of quality control, streamlining the construction process and ensuring a smooth and seamless build. With the ability to customise each piece to fit your specific project requirements, precast concrete donuts offer versatility and reliability that traditional construction methods just can’t match! 

DALLCON provides a wide selection of standard and custom precast concrete donuts to accommodate different projects. Built with engineer-approved 50 MPa concrete, these concrete donuts undergo rigorous quality and safety inspections before being dispatched to the installation site. They are not only strong and cost-effective but can also be constructed rapidly, making them suitable for projects with tight schedules.

What Can Concrete Donuts Be Used For?

Concrete donuts are highly versatile products that can be used for numerous applications such as building foundations, installing sprinkler heads, improving drainage, supporting parking structures, stormwater management, etc. 

They are a go-to solution for providing the necessary support for houses and other types of infrastructure. These donut-shaped blocks are made of reinforced concrete and are used to transfer the weight of the building to deeper, more stable soil layers below the surface, which can help ensure its long-term stability and safety.

Concrete donuts are also an increasingly popular solution for sprinkler head installation. They provide a secure, stable base that is ideal when used with pressurised water systems such as sprinklers. Concrete is known for its high compressive strength and can withstand considerable weight or pressure. Hence it makes for an excellent platform on which to place your sprinkler heads.

They are also used to improve drainage in various applications, such as landscaping, stormwater management, or foundation drainage. They provide a transition point between pipes and other drainage systems and the surrounding soil, allowing water to flow freely into the pipe and away from the areas prone to flooding.

Furthermore, concrete donuts can also be used to support parking structures and bridges, allowing them to stay strong over time without any cracking or settling.  

Concrete Donuts — Technical Specifications

DALLCON’s precast concrete donuts are designed to meet the unique height specifications of your project. They come in different shapes and sizes to suit your specific needs.

They are stackable and interchangeable and can also be buried flush to ensure your structures sit level with the ground. The durability of these concrete donuts makes them a popular choice for concrete projects. They are constructed with 50 Mpa concrete, making them resilient to harsh weather conditions and environments. Engineers and industry experts across Australia have verified this endurance.

Our concrete donuts are SL81 reinforced and have a cast-in Reid Swiftlift point, making them strong and easy to transport wherever needed.

Here are the technical specifications of our standard concrete donuts:

  • Diameter: The standard concrete donut diameter ranges from 450mm to 750mm.
  • Height: The standard height ranges from 100mm to 300mm.

We understand that every project is different and may require custom-sized precast concrete solutions. If the standard sizes do not meet your needs, reach out to us, and we will be more than happy to create a custom order that precisely fits your requirements.

With our commitment to customer satisfaction, we will work hand-in-hand with you to ensure that your project gets the exact product it needs to be successful.
