The two most common forms of damp which can affect your property are Rising Damp or Penetrating Damp. Condensation can also pose significant problems in some properties. We can offer peace of  mind by carrying out a FREE survey to assess the extent of dampness and providing you with a written report detailing our findings and the most cost effective solution to your damp problem. 

Rising Damp

Usually occurs due to a lack or failure of an existing damp course. Bridging of the damp proof course by internal plaster/external render or by high ground levels can also cause rising damp. Treatment is carried out by the installation of a chemical damp proof course (DPC). All affected wall plaster is removed to a height of one metre and a chemical damp proof course is injected.  Once the injection has been completed, the walls will be re-rendered using a waterproof sand and cement

Penetrating Damp

There are two causes. Building defects - such as defective roof coverings, cracked  brickwork, badly fitting windows/ door faulty guttering and down pipes. The second is lateral penetrating damp, caused when the external ground, abutting the wall is above internal level. As Penetrating Damp can have a serious impact on your property steps should be taken to address the underlying problems as soon as possible. Various treatments are available. Triple Treatment offer both Single Membrane and  Cementious Tanking system solutions to treat Penetrating Damp caused by high external ground levels.
