Tetrapod’s are used as amour units (concrete breakwater units) for protection of exposed coastal structures. Due to the necessity to produce thousands of precast items, durable and long-life Tetrapod Moulds are required ensuring their reusability hundreds of times in the course of the Project Cycle.Tetrapods are shaped concrete blocks, designed to protect the coastline from erosion. Pouring hydraulic concrete into special steel moulds produces tetrapod’s. The Tetrapod, which has become synonymous with wave-dissipating blocks, have a simple shape yielding superior workability, and its high stability against wave action due to strong interlocking between each block makes structures stable.
