Penetrating and Lateral Damp

LATERAL PENETRATING DAMP

This is normally caused on walls below ground floor level or within a basement area or where the walls are earth retaining causing damp patches and mould growth internally to basements and cellars below ground

PENETRATING DAMP

Penetrating damp is another form of damp which is normally caused from external sources in leaking roofs, gutters, down pipes, drain faults and internal plumbing leaks. Direct penetration of water through solid external walls is also possible especially on walls facing prevailing winds. Damp penetration can occur when a cavity is blocked or defective insulation may allow water to be transmitted directly across the walls. Old and deteriorating external renders are a frequent cause of penetrating damp along with perished mortar joints allowing water penetration.

However, penetrating damp is most commonly caused by exterior walls being in poor condition. Our wall coatings and coloured renders can cure penetrating damp with their water shedding qualities and breathable nature. Damp proofing can now be combined with long lasting decoration, eg. K-Rend

K REND

We recommend K-Rend due to its water repellent properties, low maintenance, allows the structure to breathe, has a natural looking finish and comes in an extensive colour range

The water repellent surface ensures a freshly rendered appearance for a prolonged period. The finish is drier and thus more resistant to algae growth.
