The compaction mechanism ensures that the top layer and the bottom layer form an extremely strong unit. The station consists of 2 or 4 hammers and an anvil.

The compaction mechanism developed by Kalkman gives you a technological and qualitative edge. Unlike vibrating or pressing systems, in impact compaction, the top layer is faced downwards. The result is a very intense compaction that cannot be achieved with other methods. Moreover, the impact compaction system is highly reliable and requires little maintenance.

Due to the strong compaction, less cement is needed for a product of the minimum required strength. This results in a significant reduction in CO2 emissions.
