Penetrating damp is often one of the biggest causes of damp in residential buildings. It includes any wet that has already penetrated into the structure but also includes drainage leaks. On building inspections in homes in the countryside, you will notice that the main causes of damp in almost every building are on every property, including basement drains and roof drains. If you are considering a self-sufficient lifestyle in an eco-home, make sure you consider the problems that damp can bring to your home. This guide is intended to give you a brief overview of damp and the effects it can have.
How Does Penetrating Damp Happen?
Penetrating damp will occur in two different ways. It can come from condensation on the exterior of a wall or it can come from water seeping into the structure from a floor drain or pipe. The first type of damp is known as penetrant. This occurs when condensation forms in a wet wall or wet ceiling or just about anywhere else where water could enter. It will form an invisible barrier against entering the structure so it does not really cause damp until it has already soaked into the wall. It may be a white substance that looks like water or a solid substance that feels wet and slippery.
Damp can also be formed by water leaking into the basement or sewer line. These types of damp may not be visible and are not as obvious as they are with penetrant. When this occurs, the water may leak down to other parts of the house where it is stored. If left there for too long, it can begin to cause damage. While some areas of your house may only have damp in one area, others may have damp throughout the entire property.
Our Lifestyle’s Are To Blame
One of the biggest causes for damp in the home is the way that we clean up spills and liquids. When cleaning a spill, we can often make the problem worse. When we wash a stain off with water, the liquid can still seep into the walls of a structure and cause a dampness problem. By doing the initial cleanup in this way, the damage may be worse than it is. It can leave behind a layer of dirt and debris that will need to be cleaned out by a professional. Even if it seems like the damage was minor, this type of damp can still be dangerous.
Another thing that can cause penetrating damp is a leaky drain. A leaky pipe can become completely blocked with debris and can cause the drain to become full of water. While this may look like it is draining the problem is actually worsening. This may cause the water to enter the basement through a pipe that has a hole in it or drain at the bottom of the structure. If the water stays there long enough, it can cause mildew to grow and become an odor that can be hard to get rid of.
Finally, another way that penetrating damp can occur is from the way that water seeps into the walls from a leaking roof drain or plumbing system. These types of damp are also more common than you may think. The water can remain on top of the structure for long periods of time before being drained away.
