Concrete blocks
Concrete blocks are heavy building blocks. These blocks contain min. 50% recycled sanitary ware and glass, which you can use for many different purposes. The blocks require no maintenance, can withstand all kinds of weather, and can be recycled into new concrete blocks when they have served their purpose.
Concrete building blocks
- with min. 50% recycled material
Old toilets, sinks, windows, and glass products. They do not have to end up in the landfill. We can transform glass and sanitary ware into strong concrete blocks that you can stack like building blocks.
We mix the recycled materials with recycled residual sand and collected rainwater from our own reception station. This reduces the need for new raw materials and ensures recycling.
When the concrete elements eventually become worn and need replacement, the blocks can be crushed and reused again and again.
Three types of concrete blocks
BlokAgro® is perfect for your farm or production company. They are easy to handle and install – and can be used for many different purposes.
For example, you can use BlokAgro® for:
- Building silos
- Partition walls
- Retaining walls for earth embankments
Bench, barrier, or room divider? BlokPark® are smooth concrete blocks designed with a focus on functionality and recyclability. They are especially suitable for urban areas.
For example, you can use BlokPark® for:
- Benches
- Barriers or shields
- Partitions
With stone reefs, we create growing places for seaweed, plants, and mussels in the marine environment. And we create hiding places for fish and small animals with holes and roughness. Our artificial stone reefs are called BlokRev® and can make a difference for marine life.
They can be used, for example:
- In the sea and in harbors as artificial stone reefs
- As a replacement or supplement to natural stone reefs in inner waters
- As coastal protection or breakwaters
- For flexible and protected areas for eelgrass cultivation
We base the content of BlokRev® on crushed mussel shells from Limfjorden and sea salt. From sea to sea. And the sea and currents help shape the final product. The small holes and caves in the concrete blocks are created by blue clay, which dissolves in the sea after placement. If you want to attract more fish, we can even add fish remains to the clay.

Concrete blocks are stable and durable
No matter which solution is right for you – the concrete blocks are easy to install with lifting gear. They stand stable both individually and stacked because they weigh at least 500 kg each. They are not only heavy but can also withstand frost, rain, sun, and wind. Therefore, you get maintenance-free elements for your project.
Our concrete blocks are available in over 30 different sizes – from compact 60x60x60 cm to impressive 160x80x80 cm. We regularly test the concrete to ensure you get the best and strongest product. And we guarantee a strength of up to 25 MPa.
