Tetrapod Breakwater Block Formwork

Tetrapods interlock on breakwater slopes to take wave energy apart. They are massive, cast by the thousand, and their four-legged geometry has to survive both the pour and the sea.

Zhongbian builds tetrapod moulds as heavy-duty assemblies: thick Q235 plate with fully welded rib cages sized to the block weight class, split lines and draft tuned for fast stripping.

Weight classes and leg geometry follow the coastal design drawing. Painted finish, export packing with wooden crates, and dimensional reports ship with every set.

Tetrapod moulds are used on breakwaters, harbour entrances, coastal defence works and shore-protection schemes where wave energy must be dissipated before it reaches the structure.

Coastal and port protection. Breakwaters, groynes, seawalls, harbour arms and outfall protection use interlocking armour units to dissipate wave energy and reduce overtopping.

Shore and river works. Bank protection, training walls and river outfalls are cast as close to the placement point as possible, so that heavy blocks are lifted once rather than transported twice.
