We are manufacturers of slabs and concrete pieces for outdoor flooring. Our main product is ecoGranic, a technology implemented in a prefabricated concrete that decontaminates the air through a process of natural oxidation similar to the photosynthesis of plants.    ecoGranic® is the technology developed and patented by PVT, implemented in a high strength concrete prefabrication that, in addition to fulfilling its architectural and aesthetic function, actively contributes to the elimination of pollutants from the atmosphere.    Likewise, it is very effective in the elimination of nitrogen oxides (NOx), volatile organic compounds (VOCs) and particulate matter (PM). This prefabricated product is highly ecological and sustainable. It is manufactured, among others, with materials from recycling, especially in the construction and industrial sectors.    PVT (Pavimentos de Tudela) is a company with more than 30 years of experience specialized in the manufacture of non-slip outdoor flooring. The Navarre company currently has two production centers, one located in Tudela and the other in Cabanillas with a production capacity of more than 5,000 m2 daily.
