Basement areas do not have to be completely dry. Building materials such as concrete or bricks can easily absorb a certain amount of humidity. The specific concentration of water in different building materials is decisive for the assessment. The natural moisture content of the building materials and their specific properties are decisive for the assessment, whereby the moisture content varies depending on the building material. Moisture measurement in building materials such as screed, plaster, wood, floors and ceilings is particularly important in order to detect damage and mold growth at an early stage. Depending on the material in question and the external conditions, the moisture content may be between 1.5 and 15 %. The air and humidity in the home should also be checked to prevent mold growth. In order to obtain precise values, it is advisable to measure the wall moisture. The measurement is crucial to determine whether and to what extent the building fabric has already been damaged.
Damage caused by damp masonry
Damp masonry can lead to considerable damage that goes far beyond cosmetic defects. Structural defects are a common cause of such damage. Mold is one of the most common negative reactions, which not only looks unattractive but can also be harmful to health. Damp areas also provide an ideal breeding ground for fungi, which further attack the building fabric. Furthermore, cracks can develop in the masonry, which endanger the stability of the entire building.
There are many reasons for this: structural defects, defective window seals or cracks in the wall are just a few examples. Thorough root cause analysis is necessary to identify the exact reasons for the damp. To prevent further negative reactions, it is crucial to identify the source and take appropriate countermeasures. A moisture meter can help to determine the water content and initiate the right measures against water damage.
What to do with damp masonry?
- Clarify the causes yourself
You should determine the source as precisely as possible. Whether capillary, lateral or due to condensation - a precise damage analysis is the basis for any successful renovation. Drainage depends on the cause. Our step-by-step guide takes you through all the steps from self-measurement to waterproofing.
- Initiate immediate measures
A condensation dryer or heating the room is suitable as an immediate measure. Drying appliances or targeted ventilation help to reduce the current moisture content and delay mold. Regular airing also helps to reduce excess moisture and improve the indoor climate. You can find a step-by-step guide to drying out in our extended guide. These steps are crucial for effectively combating damp.
- Implementing long-term measures
Depending on the cause, internal waterproofing, horizontal barriers or external waterproofing may be necessary to protect the building fabric in the long term. Drainage or ventilation systems can also be useful. If you want to subsequently waterproof your masonry, various methods are possible, including injection methods and horizontal barriers. The draining of the masonry can be supported by various barriers. It is important to be proactive and take concrete measures to repair the damage and protect the fabric of your home.
Drying damp areas
Drying out damp areas is an essential step in preventing damage and ensuring the stability of the masonry. There are various methods to effectively dry affected areas and protect the building fabric. Building dryers are a tried and tested solution. These classic drying methods have been in use for years, using fans and heaters to draw moisture out of the material.
Another method is infrared drying. Even small amounts of moisture can cause considerable damage. The choice of the right method depends on the type and extent of the moisture penetration. Quick action is particularly important to avoid consequential damage to the building fabric.
Infrared drying
Infrared drying is an innovative method of drying damp walls from the inside. The infrared radiation penetrates deep into the masonry, where it is converted into heat. This heat accelerates the evaporation of moisture so that the walls dry faster than with conventional methods. A major advantage of infrared drying is its noiselessness, which makes it particularly pleasant to use. In addition, the radiation temperature can be directed specifically at the wall surface to ensure effective drying. This method is particularly suitable for rooms where quick and quiet drying is required.
Electrophysical dehumidification
Electrophysical dehumidification is another effective method of drying damp walls. This technique uses electric fields to remove moisture from the masonry. Special devices are attached to the walls that generate an electric field. This field causes the water molecules in the masonry to move and be transported to the outside. Electrophysical dehumidification is not only effective, but also environmentally friendly, as it does not require any chemical additives. This method is particularly suitable for buildings where gentle and sustainable drying is required.
Subsequent sealing - is that possible?
Yes - and in many cases it is the only way to permanently renovate. Subsequent basement waterproofing is possible both from the outside by excavation and from the inside by injection or surface waterproofing. The injection method is an effective method for draining, as it can be used quickly and effectively for various causes. Wall drainage can be supported by various injection methods.
