How to deal with damp in the home?
Damp is one of the most frequent problems that everyone has encountered at one time or another in their houses in South East England and other parts of the UK. It may not seem like a big problem at first. However, damp in the home can wreak havoc in its various forms if you don’t take any proactive measures.
Apart from jeopardising the structural integrity of your house, damp problems can cause serious health issues as well. Most of you are aware that many types of damp can affect residential properties, including Condensation, Penetrating Damp, and Rising Damp. The initial step for damp treatment is to identify the type of damp that has affected your home.
Living in a damp home can be unhealthy and depressing. Thankfully, we will take you through steps on how to deal with damp in the home. With a little bit of awareness and a professional damp proof specialist by your side, you can get a hold of the problem.
What is damp proofing?
Damp proofing is a process to avoid the build-up caused by the water seeping into the walls from the ground floor surface. You can find such conditions of dampness and condensation inside the walls, floors, and ceilings.
It is a process of asphalt-based coating that is either hand-applied or sprayed to the outside of the wall and floors to keep the moisture from penetrating the property, leading to serious damage.
If executed correctly, damp-proofing is worth the cost and can save you time and money by preventing damp from getting into your residential property’s interiors. In addition, it can provide long-lasting and adequate protection for many basements and crawl spaces.
Protecting your residential home from damp damages is essential. Damp-proofing your home is the best way to prevent damp problems. Properties that are not resistant to moisture and dampness could run into more trouble with time. If you leave the problem untreated, the damp repairs can be quite expensive. For example, with a damp affected wall with patches and mould, you will have to treat and re-plaster the wall back to new.
Causes of Dampness:
Damp in residential properties are common. Following are some major reasons why damp proofing for residential properties is essential:
Rising Damp from the Ground
If the surface or land on which the property is constructed includes too much soil and allows groundwater to pass, it will result in rising damp. Usually, the material used in the foundations becomes porous, and the moisture from the ground rises through the walls due to capillary action. It means water is sucked up from the ground by the tiny tubes in the bricks.
Due to Rain
If your home walls are prone to rain or not well protected, this can result in dampness in your property. At the same time, the leaking roof also allows water to penetrate the structure, causing penetrating damp.
When warm air containing moisture gets settled on cool surfaces such as windows, ceiling, or walls, it forms water droplets, and this process is called condensation. It is the primary cause of dampness in the bathrooms and kitchens. In addition, if moist air has no outlet to pass, then water will be absorbed by the wall causing damp and ultimately leading to mould.
Other causes of damp
Besides, some other causes of dampness are:
- If your property is located on soil that you cannot drain off easily, the damp will penetrate the property.
- The location of your home also plays a vital role. The walls that get less sunlight and rain are prone to dampness.
- The newly built walls remain damp for a short period.
- A flat slope on a roof can lead to water penetration and causes dampness on a roof.
- The dampness problem also occurs due to poor artistry in the structure of the building.
Effect of dampness
The raw material such as bricks, concrete, and other stuff used in constructing the residential property also contains moisture, which normally is safe up to a certain level and optimum condition. However, if the moisture level rises above a certain level from where it is visible on your property, it can cause a real problem.
Damp can severely affect the building structure if left untreated. Some of the major effects of dampness in residential properties are as follows:
- A damp place can be a breeding ground for microbes and bugs.
- Damp can cause rust and corrosion to the metals used in the construction of the building.
- Dry rot in damp can cause decay of timber rapidly.
- It can damage your floor covering.
- The plaster on the wall becomes soft and crumbles due to dampness.
- Damp also affects paintwork, wallpaper, and other wall decoration accessories.
- When moisture penetrates the flooring, it can get loose.
- Unattractive patches on the ceiling and wall surface.
- Rise in breeding mosquitoes.
- Growth of termites.
- Paints and distempers may damage.
- Electric fitting may get damaged.
- The prolonged presence of moisture in the wall causes efflorescence to disintegrate bricks, stones, and tiles.
Methods of damp proofing
Damp proofing is a long-lasting preventive step for moisture damage. If it enters building foundations and the walls, damp proofing can help to prevent water and moisture from passing via the spaces. Furthermore, a purpose-built and safe damp proofing course can help avoid rotting of wood and structural degradation by preventing water from touching timber, resulting in dry and wet rots.
Let’s check out some reliable damp proofing treatment methods:
Membrane Damp Proofing
This process includes a membrane usually made of polythene material. The membrane is applied between the actual source of damp and the structure next to it. Apart from Polythene, some other membrane materials are bituminous felts, silicon, epoxy, mastic asphalt, polymers, or plastic. The choice of material mainly depends on the damp’s severity and the source.
Damp Proof Course (DPC)
The most common treatment for damp in a residential property is a DPC. The method is effective, but there are some guidelines that one should observe while laying DPC:
- Ensure that DPC should cover the full thickness of the wall.
- The mortar on which you want to apply DPC should be level as an uneven base can damage the DPC.
- New DPC should be applied in correct relation to the existing or old DPC to ensure an effective barrier that prevents water from seeping into the structure from the ground, walls, or ceilings.
Integral Damp Proofing
The integral damp proofing process includes adding waterproofing material with the concrete to enhance its waterproofness. These compounds come in powdered and liquid form. The combinations are used to fill the gaps in concrete and make it resilient to moisture and water.
Surface Damp Treatment
The damp and moisture can also enter when there are gaps in the finishing. So it would be best if you filled these openings and holes to prevent moisture. In this process, water repellent soaps are used, such as calcium, aluminium, and stearates. All these are quite effective and offer reliable protection from various elements.
It includes implementing a layer of rich cement mortar on the surface that makes that surface waterproof. The method is implemented by using a machine called a cement gun. The cement gun forces the mixture to the surface using compressed air. Usually, 1:3 cement mortars is applied to the affected surface to prevent moisture and dampness. To ensure stronger adhesion and tight compaction of the thick cement mortar, Guniting is performed under pressure with the help of a gun to make the surface water-resistant.
Guniting is one of the most effective methods of fixing damaged concrete work caused due to inferior construction work or other reasons.
Cavity Wall Construction
In this process, your property’s main wall is shielded by an outer wall with a cavity between both walls. The cavity then prevents the damp and moisture from coming into the main wall from the outer wall.
