Damp Proofing/Condensation Control
Due to the capillary rise of moisture from the ground within the wall fabric brought about by the breakdown of an original or the absence of an effective, horizontal/vertical damp proof course.
The Solution is to install a new damp proof course using siliconate waterproof gel, quartz injection mortar (treats rubble fill construction) or electro osmotic (non chemical) systems. Existing plasterwork to walls to be damp-proofed will invariably be contaminated due to ground salts which are hygroscopic in nature and will attract moisture from the atmosphere if left in situ. Replastering will inevitably be required using specialist lime based plasters to Expertreat specification which will allow the wall fabric to `dry down' following installation of the new damp proof course.
Condensation is airborne moisture created by the day to day activities of occupiers of properties or naturally high humidity levels generally being experienced throughout the UK. The results of condensation are mould growth, foisty odours and spoiling to decorations and furnishings. Reduction of condensation is brought about by improvements to ventilation and heating including the installation of humidistat controlled extractor fans and dehumidifiers. Please request a call back to discuss the options available.
Penetrating Dampness can also result from defects to roof coverings, flashings, rainwater goods, door and window frame sealants but can also result from high external ground levels. This form of dampness can be present in conjunction with rising dampness and/or condensation and must be dealt with by carrying out the necessary repairs externally or vertical waterproofing internally.
