  • Eco-friendliness
    Tetraneo has effective eco-friendliness because of large porosity and extremely long ridgelines. It can be seen that Tetraneo has really high affinity to the marine environment.
  • Superior economy
    Tetraneo realizes the high porosity of 60%. Therefore, total amount of concrete can be reduced. In addition, smaller blocks can be used because of high stability. As a result, Tetraneo has superior economy to those of other conventional blocks.
