These are the main areas of damp related problems that we can eliminate for you.
Practically all buildings are surrounded by natural moisture which is trying to get into the dry structure of the building.
Rising damp in buildings occurs when water from the ground rises up through the bricks and mortar of a building by a process loosely termed as ‘capillarity’.
Penetrating damp is caused by moisture that penetrates the structure of your building. There are many different factors that can cause this to happen, form a leaking roof and/or poor Guttering, to cracks and gaps in the pointing of your brickwork.
Dampness from the outside penetrates all the way through your walls, staining them and damaging your brickwork and plaster. It is also the main cause of wet rot in buildings.
Condensation is the major form of dampness affecting properties throughout the country. It is caused simply by water vapour in the atmosphere forming water droplets. Nowadays we do all we can to make our houses more insulated; Perhaps by blocking off fire places, replacing draughty windows and doors, investing in double glazing. This unfortunately can leave the water droplets with no way to escape the home, showing itself as condensation, most obvious on our windows, tilled walls etc. However, when the surface is porous, like brickwork or plaster, the water can start to cause problems because it is unnoticed and absorbed by the plaster and brickwork. Over a period of time, this can leave you with black, foul smelling mould, attributing to many health problems, including Asthma.
The main causes of dry rot in Properties today are attributed primarily to the serpula lacrymans fungus and somewhat less so to the antroda vaillantii (fibroporia). Both species of fungus cause brown (true) rot decay, removing some of the main properties of timber, leaving it brittle and weak. Dry rot has the ability to travel through building materials other than timber, giving outbreaks the potential to spread quickly through a building. Eventually the decay can cause instability and collapse in houses and other wooden structures.
Brown (true) rot can be identified by large cuboidal shaped cracks (i.e. square fractures) and usually occurs in timber in contact with damp brickwork and poorly ventilated conditions.
Wet Rot, commonly known as cellar fungus, often has the same fungal characteristics as Dry Rot. There are several species of Wet Rot so a thorough investigation is necessary for an accurate cure.
The term woodworm actually refers to the pupa which bores through the wood. The active life cycle of the woodworm species can vary from 1 year to 14 years
In the UK, the most common are the Common Furniture Beetle (Anobium punctatum), Deathwatch Beetle (Xestobium rufuvillosum), House Longhorn Beetle (Hylotrupes bajulus) and Powderpost Beetle (Lyctus brunneus). Infestations are far more likely in areas with high humidity, such as poorly-ventilated crawl spaces.
Where floors and walls are below ground level these will always be subject to lateral water penetration and the only way to make these areas dry and useable is to ‘Tank' them. We use a mesh and Platon system to do this, creating a space for the walls to ‘breath’and dry out to some extent.
