Rising damp treatment in Gondomar
Gondomar's river valleys trap fog longer than coastal Porto — external walls stay damp for weeks, slowing post-injection drying. Damp proofing Gondomar hillside homes often combines rear-elevation tanking on semi-buried floors with front-elevation DPC injection. Rio Tinto and Fânzeres apartment blocks show the same pavement-bridging pattern as central Porto: 1970s patio raises that shove soil above the original slate course. We restore a continuous barrier without removing terraces when injection from inside is viable. Melres and Baguim do Monte quintas frequently have barrel-vault cellars used for storage; we provide negative-side slurry specs before owners convert space to habitable use — avoiding the €12,000 rework common when tanking is skipped.
