Mombasa Coastal Damp proofing

The Coastal Capillary Threat

Nyali Reefs Resort faced severe rising damp along all ground-floor ocean-view villa walls. Pushing seawater tables saturated the coral brick masonry, carrying mineral salts upwards. Upon evaporating, these salts expanded, destroying the interior plaster, bubbling paintwork, and producing musty odors.

The Chemical DPC Insertion

Phemat installed a new chemical Damp Proof Course (DPC) line. We drilled horizontal holes along mortar bed joints and injected silicone-barrier micro-emulsions. This created a continuous water-repellent barrier. We stripped the contaminated salty plaster, treated the core masonry with salt neutralizers, and replastered with salt-retardant breathing mortar.
