Types of Damp
This is caused by moisture which penetrates through the roof or walls this is usually due to insufficient weather protection i.e. roof membranes that have become faulty broken roof tiles this lets the rain water slowly penetrate through to the inside of the building the same goes for outside walls where they have wall coverings such as spritz or graphiata or even just plain concrete.
Usually is caused by ineffective plumbing and piping. Here in Cyprus Plastic piping is used commonly because of its low cost it can become brittle and fracture.
Usually plastic pipes are glued together but we have found numerous instances where this has not been carried out. We have found this especially on drainage piping for bathrooms and rain water drain pipes.
….There is a train of thought that the concrete will hold and seal it together!!
The fact is it will leak and cause damp problems. We have found this to be the case many times especially for roof drainage pipes.
Air conditioning drains are often connected to rainwater drain pipes and a constant flow of water is passed through them in the summer. Rain water drains often block with leaves and dirt causing a backup of water. This water will then seep through the joints that are not glued, allowing water into the fabric of the property.
Cyprus also has its fair share of earthquakes this can crack walls and rupture internal piping once again causing problems!
Many areas of Cyprus have extremely high water pressure levels for the mains drinking water supply this has been responsible for quite a few burst pipes due to excess pressure
Tiled shower trays can cause problems too, if they were not properly ‘tanked’ prior to tiling. Contrary to popular belief waterproof tiles and grout are generally only water resistant and not waterproof.
Tanking is a term for a waterproofing method whereby a waterproof agent is applied in several coats to form a watertight container.
Condensation occurs when humid air and water vapor settle on a cold surface forming water droplets. In Cyprus our properties generally do not have wall cavities or thermal insulation, creating cold walls in the winter.
Heating the rooms sufficiently will help but good ventilation is also necessary. Mobile Gas heaters can cause condensation and the drying of clothes on radiators will all add to the problem.
….Generally the lifestyle of the occupants determines how much condensation is created!
Verandas, patios and roof gardens
Verandas and patios will contribute to damp if they are regularly hosed down, The excess water can seep through the tiles into the base concrete and will travel up walls or through ceilings causing further damp. Use a mop and bucket it’s quicker and saves valuable water.A good patio sealer is a good idea.
What ever the cause of damp is it will need to stop before it causes structural damage.
