The data shown reflects the latest models and versions of the machines. The actual production capacity of the plant is not exact and depends on many factors, such as the type and quality of the aggregates, moisture content, concrete mix design, type of product to be manufactured, experience and skill of the operators, etc. Usually, this actual capacity is typically in the approximate range of 80-90% once the learning curve has been overcome, always bearing in mind that start-ups and shutdowns are not taken into account in these times.

MOBILE BLOCK MACHINES (LAYING TYPE)

Mobile block machines, also known as laying machines, allow blocks to be manufactured directly on the ground, without the need for trays or other auxiliary extraction systems, simplifying plant operation and reducing the investment required. They are ideal for flexible production, offering high mobility, low maintenance and ease of use. Available in semi-automatic and automatic versions, these machines are the perfect solution for those who want to start manufacturing blocks or expand their production without large infrastructures and with a limited investment.

Frequently asked questions
What products can I manufacture with a Grupex block making machine?

Our high-performance block making machines allow you to efficiently produce all types of concrete products — blocks, paving stones, kerbs, tiles, screen blocks, drainage channels, hollow blocks, partition blocks and special elements — simply by changing the mould installed.

What is the difference between fixed block machines and mobile block machines?

Fixed (stationary): Ideal for high-volume, continuous production lines; they offer seamless integration with other automation components such as hoppers, handling systems, palletising, and curing units, ensuring a fully automated and consistent workflow. These systems typically require a higher initial investment.

Mobile (laying hens): A compact, versatile design that allows for direct on-floor operation without the need for production pallets, making it the ideal solution for temporary or budget-sensitive projects. Its integrated vibration and compaction system ensures steady production rates with a minimal investment, eliminating the need for costly handling systems and simplifying civil works.

Does the machine include moulds?

Each plant can be equipped with the necessary moulds to produce any required concrete products. Custom or additional moulds can also be requested for specific product formats.

Can production be automated?

Absolutely. We offer full or partial integration with fully automated handling and operation systems — elevators, lowerators, conveyor belts, cubers, turnover units, brushes, strapping machines, and more — tailored to the specific capacity and requirements of each project. This ensures maximised production output, streamlined operations, and reduced labour costs.

Do you offer international shipping and support?

Yes. We supply machinery and equipment to over 25 countries, providing both remote and on-site technical support to guarantee the optimal performance of every unit under all conditions.

What training do we offer for the operations team?

We provide tailored training programs covering equipment operation, preventive and corrective maintenance, and process optimisation, ensuring your operators become fully self-sufficient and achieve peak efficiency.
