本研究的目的是确定位于圣地亚哥教堂（赫雷斯德拉弗龙特拉，西班牙）的损坏的原因，如支柱的倒塌，墙壁和拱顶裂缝等，这些都发生在其五百年的存在。所进行的调查工作中最重要的方面与使用组合非破坏性技术有关，例如使用地质雷达与超声波检测支柱和主墙内的空隙，视频内窥镜，温度记录系统，加速器和其他地震技术，减少多达20%的挖掘和不必要的钻孔，以了解元素的组成和异质性。此外，通过使用这些技术，变形模量E -动态和静态-在不同高度的支柱，以及承载能力，不仅可以得到的支柱，而且在底部，中心和上部的每个支柱。调查的一个重要目标是确定1961年开发的加固工程的范围，检查混凝土构件的几何特征和保护状况。从收集的所有数据中，可以确定现有损坏和病理的起源，因此可以适当地进行建筑物修复。
The aim of this research has been to determine the causes of the damages located in Santiago church (Jerez de la Frontera, Spain), such as the collapse of the pillars, the wall and vault fissures and others, which have occurred over its five hundred year existence. The most significant aspects of the investigation works performed are related to the use of combined non-destructive techniques, such as the use of georadar with ultrasounds to detect voids inside pillars and main walls, videoscope, thermograph systems, accelerator and other seismic techniques, reducing up to 20% the excavations and unnecessary bore holes in order to know the composition and heterogeneities of the elements. In addition, by using these techniques, the deformation module E – dynamic and static – at different heights in pillars, as well as the bearing capacity could be obtained, not only among the pillars, but also at the bottom, central and upper parts of each pillar. An important goal of the investigation was to determine the extent of the reinforcement works developed in 1961, checking geometric features and conservation status of concrete elements. From all the data collected, the origin of the existing damages and pathologies can be set out, and hence, a building restoration can be adequately carried out.
