Rising damp treatment in Leça da Palmeira

Leça da Palmeira sits in the Atlantic spray zone — damp proofing here is marine-grade by default. West-facing elevations on Monte de São Brás take direct salt aerosol; standard interior injection fixes rising damp at the base but leaves chloride contamination in the plaster matrix. We poultice salts before applying salt-retardant lime render. Marina-adjacent apartments near the Leça harbour show corroded cavity ties and wind-driven rain penetration misread as rising damp. Our survey distinguishes lateral ingress at mid-wall height from capillary rise at the skirting. Boa Nova cliff-top properties combine coastal exposure with hillside runoff — dual remediation paths in one report. We specify silane treatments rated to proPERLA marine exposure classes for external breathability without film formation.
