Tetrapod mould 1T/1.5T/3T/5T/7.8T

Tetrapod are concrete structures that protect shorelines and river banks by acting as breakwaters. Tetrapods, after the Greek word for "four feet", are shaped like a tetrahedron: a triangular pyramid with four faces and four corners. The legs of the tetrapods hook into each other, creating a row of stable concrete breakwaters along the coast.
We carry various different tetrapod moulds, including a 1 tonne, 1.5 tonne, 3 tonne, 5 tonne and 7.8 tonne version (metric tonnes). Because they are very large and consist of a large amount of concrete, it takes longer to create a ready-to-use tetrapod than a standard concrete block. While a concrete block takes approximately 24 hours, it can take anywhere from 48 to 72 hours for a tetrapod to cure properly and be ready for use, depending on local conditions.
