Frequently asked questions

What is the price of a block-making machine, such as the G12?
The price varies depending on the configuration, additional options, and specific project requirements. You can request a personalised quote with no obligation via the contact form.
What types of products can be manufactured with the G12?
The G12 allows you to manufacture a wide range of precast elements: hollow blocks, paving stones, vaulted blocks, partition blocks and more, even in double-layer versions, thanks to its versatile design and the ability to adapt production to your needs.
Does the G12 require civil engineering works or special installations?
Our laying machines are designed to work with minimal civil engineering, requiring only a levelled concrete slab. This industrial laying machine is designed to work directly on the ground, eliminating the need for fixed structures or trays, which significantly reduces initial costs.
What is the difference between a block layer and a fixed machine?
The main difference is that the block-making machine, such as the G12, does not require trays, complex installations, curing systems, or racks. It produces the blocks directly on a concrete slab, which simplifies operation, significantly reduces initial investment, and allows for high production. In addition, its mobile design allows it to work in different locations, bringing flexibility and efficiency to the manufacturing process.
What maintenance does the G12 require?
The G12 is designed for simple and accessible maintenance. It requires:
  • Regular checks of the hydraulic system (level, pressure, possible leaks).
  • Regular cleaning of the hopper and work area to prevent material build-up.
  • Basic lubrication and adjustment of components according to frequency of use.
Its modular and accessible design allows these tasks to be performed quickly, reducing downtime and maintenance costs.
