Tetrapod moulds: strong moulds for strong projects

Tetrapods are large concrete breakwaters. They protect coastlines against erosion and keep harbours safe. In Japan, nearly half the coastline is covered with these structures. With a coastline of 35,000 kilometres and frequent typhoons and tsunamis, Japan would lose a significant part of its landmass without them. But Japan isn’t the only country using tetrapods, it’s simply the most popular example. You’ll also find them in France, the United States, the Netherlands, Australia, and Germany. Our own moulds have even been used for coastline projects in Italy, Poland, Brazil and South-Africa. This video shows exactly what we mean:

Waves are powerful, and if you don’t have the right protection, they’ll eat away at coastlines and damage infrastructure. That’s where tetrapods come in. Thanks to their unique four-legged shape, they break up wave energy instead of just deflecting it. Water flows around them rather than slamming straight into them, which means less force, less erosion, and a lot more stability. The result? Long-term coastal protection that actually works.

We know what you’re thinking: why would you produce tetrapods? Who buys them?

We manufacture our tetrapod moulds using only high-quality S355 structural steel. That means they’re built to last for a very long time: at least 10 years, even when you use them extensively.

A clever design ensures you can produce tetrapods quickly and smoothly. Simply leave the concrete to set in the moulds for three days before removal, then immediately reuse them for the next batch.

We offer moulds in various sizes:

The only real difference between our concrete block moulds and tetrapod moulds lies in how they open: tetrapod moulds are secured with bolt-and-nut connections. However, due to their complex shape, it’s even more important to properly vibrate the fluid concrete. This helps eliminate air bubbles and ensures that all the components are thoroughly mixed.

We recommend casting an anchor along with the blocks to ensure they can be lifted safely and effectively. Depending on the size and weight of your concrete tetrapod, using multiple anchors may be necessary. Additionally, you’ll need a lifting chain for secure handling.
