Penetrative Damp

Penetrative damp is known technically as ‘water ingress’ and refers to any moisture seeping into the fabric of a building other than through Rising Damp. Penetrative damp can cause structural and cosmetic damage to a building, and health issues for residents if left untreated for a prolonged time.


Symptoms of penetrative damp

  • Peeling wallpaper

  • Plaster falling off walls

  • ‘Blown’ plaster

  • Internal plaster stained




Action required:

Working out the cause of penetrative damp involves careful detection work. The source of the damage can be obscured by climbing plants and roots which can undermine the foundations of a building and causing breaks in damp courses.

Assessment also requires a thorough knowledge of structural requirements to manage moisture, such as necessary underfloor ventilation.

Our penetrative damp treatment solutions include unblocking gutters, repairing leaking pipes and uncapped chimney pots, replacing defective external plasterwork with our waterproof rendering system, making good internal plaster.
