Analysis Method for Studying Groundwater under a Church

Abstract

[EN] The Church of Asunción of Llíria (Valencia, Spain) is one of the best examples of the Valencian Baroque of the seventeenth century. This research has been based on the study of the building from an urban, historical, and especially, a constructive view. In fact, the location of this particular church is very unique because it is embedded within the mountain. For the construction of the church, first, it was necessary to dig into the mountain. Thus, there is a strong gap between the main entrance of the church and the rear. This research work provides the analysis of the ground humidity throughout the GPR technique. We have analyzed the subsoil of the whole church by various cuts or paths, longitudinal and transversal measurements that have allowed us to produce a three-dimensional model of the land on which the church stands. We have also analyzed the homogeneity or the heterogeneity of the land in each area and the presence of certain ground water routes. It has been analyzed the rising damp on the walls and pillars of the church. To this end, it has been employed a moisture analyzer and it has been obtained the moisture content over a period of six months. With this information it has been able to identify those points that are systematically wetter.
