What causes rising damp?


Rising Damp in buildings occurs when water from the ground rises up through the bricks and mortar of a building by capillary action.

To give a comparison, imagine a sponge sitting in your sink soaking up water, now think of that in your walls! in simple terms, that is what Rising Damp is; the water rises up the porous wall of a building and is absorbed like a sponge absorbs water. If left untreated, the water evaporates, and more is soaked up from the ground, resulting in an ever-increasing Rising Damp problem.

Sounds horrible right? Well, it gets worse! As you can imagine, the water that is soaked up from the ground is not nice, fresh clean water, it’s dirty, smelly water that ends up stuck in your walls and as most of us know, water damage is probably the worst things that can happen to a home. Well that and termites!

Preventing Rising Damp or curing the problem entirely is a must if you want to keep the value of your property intact and also protect your family and the people you care about from the health risks associated with Rising Damp.
