Rising damp treatment

What is condensation, rising damp and penetrating damp?

Condensation, rising damp and penetrating damp are the most common types of damp found in residential and commercial properties. Condensation is the least severe, and can generally be solved by improving ventilation and reducing humidity.

Rising damp is caused by water being absorbed into brick walls from the ground or underground, and is often an issue in basements and on ground floors. Penetrating damp is caused by water absorption from the exterior to the interior through cracks and leaking pipes or gutters, moving horizontally, where rising damp spreads vertically.

Damp proofing for rising damp and penetrating damp

Damp in your property is not only unsightly, but can also cause health issues if left untreated. The musty smell it causes is unpleasant, and black mould and the damp itself can cause wallpaper to spoil and peel and lead to other issues such as decaying timber and damaged plaster.

Damp proofing using a DPC and/or membrane prevents the affected walls from absorbing the water causing the damp, providing a protective layer. Existing damp proof coursing can deteriorate over time, so even treated properties may need further attention down the line.
