Large prefabricated intermodal track slabs

Prefabricated large-format intermodal slabs are designed for track and surface construction in intermodal terminals, seaports, logistics centers, and transshipment yards with high operational intensity. The system is adapted for both road and rail traffic, allowing it to be used in areas where road and railway infrastructure operate together.

This solution represents an example of the application of modern prefabrication technologies in demanding operational environments characterized by high concentrated loads and dynamic impacts. The slab structure is designed based on an analysis of loads generated by gantry cranes, reach stackers, heavy-duty trucks, and railway rolling stock operating within the terminal area.

The system developed by KZN Contrack responds to growing market demands for load-bearing capacity, durability, rapid project execution, and optimized maintenance costs throughout the entire life cycle of the infrastructure.

Our solution stands out from currently used systems primarily in the following aspects:

• concrete prefabricated elements designed for heavy road and rail loads;

• high initial quality achieved through production under controlled conditions in a prefabrication facility;

• large-format slabs reducing the number of expansion joints;

• a properly designed drainage system enabling efficient removal of water and operational contaminants;

• a significant reduction in installation time, even down to 72 hours, regardless of weather conditions;

• in the event of wear or damage to the steel component, fast replacement is possible by cutting out and bonding new elements without interfering with the concrete surface.
