Rising damp treatment in Porto
Porto's UNESCO-listed core packs thousands of granite townhouses where groundwater rides capillary action up to 1.2 m every winter. In Cedofeita and Bonfim, raised street levels from 20th-century paving often bridge whatever slate DPC existed in the 1890s — meter readings at skirting height routinely hit 80–95% WME even when upper walls read dry. We treat rising damp treatment Porto searches as emergency-adjacent: peeling plaster near São Bento and musty ground-floor shops along Rua das Flores need diagnosis before replastering, not after. Our surveyors know which Miragaia blocks share party walls with active wine cellars (lateral moisture, not rising damp) versus which Sé parish buildings need mortar-bed injection only. Atlantic rainfall here exceeds 1,200 mm annually. That volume keeps soil permanently damp against foundations — chemical DPC injection plus breathable lime replaster is the standard fix we specify for habitable ground floors.
