Grooved Hollowcore: a simplified way to significantly reduce concrete consupmtion and increase profit margins

A method to make hollowcore slabs fixed at their endswhich allows for a reduction of up to 20% of the depth andconsumption of concrete of finished floors has been devel-oped, thoroughly tested and protected by patents by theengineering company Elastic Potential, in Barcelona, Spain.The method consis...
