Damp proof membrane is used to treat existing damp problems or to prevent damp from becoming a problem in the carpet flood damage Melbourne first place. This is a quick guide to answer frequently asked questions about damp problems.

Where does damp come from?

Damp comes from any source of water or moisture, this can be the ground, condensation caused by changes in temperature in the home, steam from the shower or bath, your taps, shower, bath or sink or a leaking pipe. No house is entirely water tight because of the existence of windows, doors and ground water and so damp is fairly commonplace in homes across the UK but also fairly easy to treat if caught early.

How to spot damp in the house?

Damp usually forms in patches on ceilings, walls or on the grouting between tiles and usually looks dark grey, dark green or black in colour. Other signs of damp include damp or wet patches on the wall or ceiling (these appear darker than the unaffected areas) and these patches can cause paint to flake or wallpaper to peel. In new areas of damp you can often spot condensation-like droplets on the wall or ceiling, this often happens when the damp is caused by a leaking pipe or an overfilled bath. Damp caused by a leak is also often characterized by a bulge in the ceiling and this is a sure sign of something that needs dealing with immediately or there’s a danger of it bursting and flooding the room.

What is rising damp?

Rising damp is when the fabric of your home (i.e. the bricks, timber frame etc) soaks up water from the ground and transports it up the interior or exterior walls of your home, outhouse or garage. Water “climbs” the walls using whatever it can, from cracks and porous materials to salt that is present within the walls. Rising damp is a common problem in houses which do not have some sort of damp proofing or damp proof membrane installed and both of these can prevent the problem or stop it from occurring again.

How can you identify if you have rising damp?

Houses are often misdiagnosed as having rising damp but a general rule is that if the damp patch on your wall appears to have started at ground level and is moving upwards, it’s likely to be rising damp. The damp patch is unlikely to get above one metre in height as at that point gravity takes over and pushes it back down but this is entirely dependent on what the water can find to cling onto.
