TU1208 GPR Association was founded in September 2017 as a follow-up initiative of COST (European Cooperation in Science and Technology) Action TU1208 "Civil engineering applications of Ground Penetrating Radar," which ended in October 2017. We founded this non-profit association to keep our scientific network alive and cohesive, continue the excellent work that was done in the framework of the Action, and further support cooperation between Universities, research centres, private companies and public agencies active in the GPR field. TU1208 GPR Association inherited the same primary objective of COST Action TU108: exchange and increase scientific-technical knowledge and experience of GPR technique while promoting the effective use of this safe and non-destructive method. Our association is open to experts from all over the world, and not 'only' to those who were previously Members of COST Action TU1208. The research activities supported by TU1208 GPR Association cover all areas of GPR technology, methodology, and applications. TU1208 GPR Association is active in the organization of scientific events, such as conferences, workshops, and training schools; moreover, the association supports the participation of its Members to relevant events organized by other institutions and funds research visits. TU1208 GPR Association carries out editorial activities, such as the publication and dissemination of proceedings of events, educational material, journal papers, books, and multimedia documents useful to spread out the results of the studies and initiatives fulfilled by its Members. We publish an open access peer-reviewed scientific journal: Ground Penetrating Radar. The activities of the association include any other initiative useful to foster the achievement of its primary objective.Key principles: Cooperation - Sharing - Open science - Excellence - Embracing diversity - Inclusiveness - Innovation - Bottom-up
