Damp proofing

Rising Damp occurs when ground

water travels upward through porours building materials such as bricks,sandstone & mortar this is caused by capillary action and usually to a height of 1mr to 1.5mr.Rising damp can identified

by a tide mark on the affected wall.This is caused by soluble salts ( nitrates & chlorides) contained in the ground water.

Due to evaporation these salts

become apparent and contaminate the plaster.

All Damp proofing work carried out by

Campbell Damp Control is to

British standard

BS 6576;2005+A1:2012

Remedial repairs include

: Removal of contaminated plaster

: DPC injections

: Salt neutralization

: Water proof render

: Plaster skim finish

Condensation dampness’ is a condition that affects millions of homes in the UK and is particularly common in houses which are poorly heated and insulated i.e. have more cold surfaces and usually gets worse in winter. This problem can lead to staining and mould growth damaging wallpaper, wall surfaces, window frames, furniture and clothing. The tiny spores produced by this mould and higher numbers of dust mites due to the moist conditions can also increase the risk of illness such as asthma and bronchitis.

All air contains a certain amount of ‘invisible’ water vapour. The higher the temperature of the air the more water vapour it can hold. Condensation frequently occurs when air carrying vapour comes into contact with a cool surface. At this reduced temperature less water can be held and it is deposited. It is for this reason that the bathroom mirror steams up after a shower or a window when you breath on it.

Remedial repairs include

: Ventilation

: Insulation

: Anti fungal treatment to mould
