Damp Proofing In The North East

There are various reasons for rising damp – the failure of an existing damp proof course (dpc), bridging due to the raising of external ground or internal floor levels, or in older buildings, the complete absence of a damp proof course.                         Brick, stone and mortar are porous allowing damp from the ground to rise by capillary action, carrying with it ground salts including chlorides and nitrates.


These salts from the ground can absorb moisture from the atmosphere leading to wall dampness in conditions of high relative humidity. Also they can ruin decorations and break down internal plaster.


We provide a 20 year guarantee with our damp proof course.


An additional insurance backed guarantee can be purchased.

Re-plastering – incorporating a damp proof course injection


Re-plastering after our injected chemical damp proof course is an integral part of our damp proof course. The importance of our re-plastering specification can’t be stressed enough. Water rising from the ground contains mineral salts which are hygroscopic and can attract moisture from the atmosphere. Our injected damp proof course along with our specialist re-plastering work together to control the effects of rising dampness to the property.
