Understanding Rising Dampness
Rising damp is a common issue that occurs when moisture from the ground travels up through walls, causing damage to plaster, paint, and wallpaper. It can even lead to structural damage to masonry and timber. To effectively treat rising damp, it is essential to understand its root causes and implement the appropriate solutions.
In this section, we will delve into the science behind rising damp, its common causes, and how to identify its signs, so you can begin the rising damp treatment process with confidence.
The Science Behind Rising Damp
Rising damp occurs due to capillary action in masonry, where moisture is drawn upward through tiny channels in the brickwork and mortar. This moisture can travel up to 1.5 meters from the source, spreading across the internal and external walls of a property. The small-sized capillaries in masonry facilitate a greater degree of moisture transfer, leading to damp interior walls and the tell-tale signs of rising damp.
Understanding this capillary action is crucial in order to effectively diagnose and treat rising damp. By recognising how moisture rises and spreads through the building materials and affected walls, you can take the necessary steps to fix rising damp and prevent it from recurring in the future.
Common Causes of Rising Damp
The most common causes of rising damp are typically attributed to failed or absent damp proof courses (DPCs) and bridged DPCs. A damp proof course is a barrier installed at the lower level of the wall to inhibit the upward movement of water. It is usually constructed from non-absorbent, water-resistant materials such as slate, bitumen, plastic, and a damp proof membrane. In addition to rising damp, penetrating can also cause issues in buildings if not addressed properly.
Factors like subsidence, bridging, and a rise in ground levels outside can compromise the damp proof course and lead to rising damp issues. In such cases, it is crucial to identify the cause and implement appropriate solutions, such as installing a remedial new damp proof course or addressing any bridging issues, to stop rising damp in its tracks.
Identifying Signs of Rising Damp
Before you can tackle rising damp, it is vital to identify its signs on both internal and external walls of your property. Recognising these rising damp signs will enable you to take timely action and prevent further damage.
In the following subsections, we will explore the symptoms of rising damp on internal and external walls, so you can accurately diagnose the issue and initiate the necessary treatment.
Internal Wall Symptoms
Some visual indicators of rising damp on internal walls include tide marks, salt deposits, damp patches, and bubbling plaster. Tide mark marks are brown or yellow lines in the plaster above the skirting, caused by the capillaries in the brick ceasing to transport moisture upwards due to gravity and natural evaporation. Salt deposits, on the other hand, are white, powdery substances on damp walls resulting from the evaporation of water and the deposition of salts like sulphates and hygroscopic salts such as nitrates and chlorides.
To address these symptoms, it is crucial to treat the rising damp problem effectively and use appropriate materials like salt retardant wall plaster when replastering the internal walls. This will help to prevent future moisture problems and ensure the longevity of your property.
External Wall Symptoms
When it comes to external walls, evidence of rising damp may include crumbling mortar, salt deposits, and tide marks. Spotting these signs early can help you take prompt action to treat rising damp and prevent further damage to your property.
A thorough inspection of your property by a rising damp treatment specialist can help diagnose the issue and suggest the most suitable treatment for your specific situation.
The Importance of Accurate Diagnosis
Accurate diagnosis of rising damp is critical to avoid costly mistakes and to ensure that the correct treatment is applied. Misdiagnosis can lead to unnecessary treatments and ongoing issues, which can further damage your property and increase repair costs.
In the following subsection, we will discuss the consequences of misdiagnosis and the importance of seeking professional help to accurately identify and treat rising damp.
Misdiagnosis and Its Consequences
Misdiagnosing rising damp can have numerous repercussions, including unwarranted treatments and persistent issues. Applying incorrect solutions not only wastes time and resources, but also fails to address the root cause of the problem. Furthermore, untreated rising damp can lead to dampness at the base of the wall, high moisture levels in the skirting boards, damage to plaster and decorations, and even deterioration and weakening of walls.
To avoid these consequences, it is crucial to consult a qualified professional who can inspect your property, detect the indicators of rising damp, and suggest the most appropriate treatment for your specific situation. This will ensure that your property receives the right care and attention, helping you maintain its value and structural integrity.
Rising Damp Treatment Options
Once you have accurately diagnosed the issue, it is time to explore various treatment options. There are several effective methods for treating rising damp, such as chemical DPC injections and electro-osmotic systems.
In the subsequent subsections, we will delve into the processes and effectiveness of these treatment options, so you can make an informed decision about the best course of action for your property.
Chemical DPC Injections
Chemical DPC injections involve injecting a damp proofing cream, such as Kiesol C or Aida, into the side cavity wall to form a barrier against rising damp. This treatment method is highly effective and widely used in the industry. The process involves the following steps:
Lift the skirting boards around the affected area.
Remove any plaster that has been corrupted by hygroscopic salts.
Prepare the area before any work can be done.
Install a remedial damp proof course using the DPC injection method.
The use of chemical DPC injections offers long-lasting protection against rising damp and is an ideal solution for many properties. However, it is crucial to consult a rising damp treatment specialist to determine whether this treatment method is suitable for your specific situation and to ensure proper installation for optimal results.
Electro Osmotic Systems
An alternative treatment method for rising damp is electro osmotic systems, which utilise a low voltage electrical current to counteract capillary forces and impede the rise of dampness. These systems generate a small electric current at the wall, creating an electro-osmotic pressure gradient that pushes the water back into the ground.
Electro-osmotic systems have several advantages.
They are non-invasive and can be implemented without requiring extensive construction work.
They are relatively cost-effective.
They can be installed quickly.
However, it is important to note that electro-osmotic systems may not be suitable for all types of walls and may not be effective in certain scenarios.
It is important to consult with a professional to determine if an electro osmotic system is the best solution for your property.
Repairing Damaged Surfaces After Treatment
After treating rising damp, it is essential to repair any damaged surfaces, such as plaster, paint, and flooring. Properly addressing these damages will help restore the appearance and functionality of your property, as well as prevent future moisture problems.
In the following subsections, we will discuss the process of replastering walls using salt-resistant plasters and considerations for choosing breathable flooring materials.
Replastering and Salt-Resistant Plasters
Replastering involves removing the existing plaster from walls and applying a new layer of plaster. This process is often undertaken to repair damaged or deteriorated plaster, enhance the aesthetic of walls, or as part of a damp proofing treatment.
When replastering walls affected by rising damp, it is recommended to use salt-resistant plasters to provide additional protection against future moisture problems. Salt-resistant plasters are developed to be more resilient to the salts typically present in rising damp, which can cause harm to traditional plasters. Consequently, they are a more suitable option for replastering walls that have been affected by rising damp.
Proper application of salt-resistant plasters, along with appropriate treatment, can help prevent future rising damp issues and maintain the integrity of your property.
Flooring Considerations
In addition to repairing damaged exterior walls first, it is important to address flooring issues that may have resulted from rising damp. Breathable flooring materials, such as vinyl, ceramic tiles, or concrete, can help prevent rising damp by allowing moisture to evaporate.
When selecting flooring materials, consider their resistance to moisture and their compatibility with existing building materials. Consulting with a professional can help you make the best decision for your property and ensure a successful rising damp treatment process.
Preventing Future Rising Damp Issues
Preventing future rising damp problems is just as important as treating existing ones. By adopting regular property maintenance and humidity control measures, you can safeguard your property against the recurrence of rising damp and ensure its long-term health.
