In the difficult economic times we are currently experiencing, and particularly in the case of the construction sector, the only companies that have been able to prevail have been those that have opted for innovating and differentiating their products. A clear example can be found in one of Prensoland’s clients: the firm Viguetas Navarras S. L., founded in 1962 and based in Huarte - Navarra, is a leader in the manufactur- ing of prestressed concrete elements. One of the key factors of Viguetas Navarras S. L.’s success has been the floor slabs manufactured using the Tensyland EV5 machine.
