Abstract
ABSTRACTIn this article, we briefly discuss the main features and the most relevant achievements of the Project for the Geometrical Correction of Mexico City´s Cathedral and Sagrario church during which these two monuments were underexcavated to correct differential settlements and where the underlying subsoil was later hardened with mortar grouts. Based upon instrumental observations and field test data, we describe the effects on the subsoil of the selective soil hardening that took place when underexcavation finished. We also look at the behaviour of both churches after more than 13 years after the end of underexcavation and soil hardening. Topographical data show that soil hardening has positively modified the response of both temples and that further interventions are not likely to be needed in the short and mid term.
