Water Ingress Through Brick Wall: Cause and Cure

Water ingress in brick walls is a common issue faced by many homeowners in the UK. This phenomenon, where water penetrates through the bricks and mortar of a building, can lead to a range of problems, from damp patches on internal walls to serious structural damage over time. Understanding the causes and solutions for water ingress is crucial for maintaining the integrity and comfort of your home.

 

Causes of Water Ingress in Brick Walls

 

The primary cause of water ingress in brick walls is the permeability of the materials. Bricks and mortar, especially in older homes, can become porous over time. This porosity allows water to seep through, particularly during heavy rainfall or in areas with high humidity. Other contributing factors include:

 

• Faulty Guttering and Drainpipes: Blocked or damaged guttering can lead to water overflow, which then seeps into the brickwork.
• Cracks in the Walls: Cracks, whether due to settling, temperature changes, or poor construction, can become channels for water to enter.
• Inadequate Pointing: Deteriorated or improper pointing in brickwork can increase the risk of water ingress.
• Condensation Build-Up: Poor ventilation inside the house can lead to condensation, which may eventually penetrate exterior walls.

 

The Impacts of Water Ingress

 

Water ingress can have several detrimental impacts on a property:

 

• Structural Damage: Prolonged exposure to moisture can weaken the structural integrity of the walls.
• Mould and Mildew Growth: Damp conditions are ideal for the growth of mould and mildew, which can pose health risks.
• Thermal Inefficiency: Wet walls lose heat more rapidly, leading to higher energy bills.
• Aesthetic Damage: Water stains and peeling paint can affect the appearance of your home.

 

Long-term Benefits of Addressing Water Ingress

Investing in solutions to prevent water ingress has long-term benefits for homeowners:

• Preservation of Property Value: A well-maintained, water ingress-free home retains its value better in the property market.
• Reduced Repair Costs: Addressing water ingress early can prevent more severe structural issues, saving significant repair costs down the line.
• Improved Living Environment: A dry, mould-free home is healthier and more comfortable to live in.
• Energy Efficiency: Dry walls have better thermal properties, leading to reduced heating costs and a smaller carbon footprint.

Preventative Maintenance Tips

In addition to professional solutions, homeowners can adopt simple preventative measures to reduce the risk of water ingress:

• Regular Inspections: Periodic checks of the exterior walls can help identify potential issues early, such as cracks or signs of wear in the mortar.
• Maintaining Surrounding Landscaping: Overgrown vegetation can contribute to dampness in walls. Keeping trees and shrubs trimmed back from the house can help mitigate this.
• Ensuring Proper Interior Ventilation: Use of exhaust fans in kitchens and bathrooms and regular airing of the home can significantly reduce indoor humidity levels.

Solutions for Water Ingress in Brick Walls

 

1. Exterior Wall Coatings

 

A highly effective solution for preventing water ingress is the application of exterior wall coatings. These specialised coatings are designed to be waterproof and breathable, allowing moisture from inside the house to escape while preventing water from entering.

 

Advancements in Weatherproofing Technologies

The field of weatherproofing has seen significant advancements in recent years. Innovative products and application techniques have enhanced the efficacy and durability of exterior wall coatings. These advancements include:

• Nano-technology Coatings: Nano-technology coatings are a type of water-resistant coating that uses nanoparticles to create a barrier that prevents water from penetrating the surface. These coatings are typically breathable, meaning that they allow moisture from inside the house to escape, preventing the buildup of mold and mildew. Nano-technology coatings are available in a variety of colors and finishes, and can be applied to a variety of surfaces, including siding, roofing, and windows.
• Eco-friendly Options: Environmentally conscious homeowners can opt for sustainable, eco-friendly coating solutions that reduce environmental impact without compromising on performance.
• Advanced Application Techniques: Advanced wall coating application techniques have significantly improved in efficiency and effectiveness. 
  • Techniques like airless spray application ensure uniform and rapid coverage, while plural component spray systems are ideal for fast-curing, high-performance coatings. 
  • Heat-induced curing accelerates the setting process, particularly useful in cooler climates. 
  • For textured finishes, specialized methods like trowel or roller applications are employed. 
  • Elastomeric coatings, requiring flexible application for weatherproofing, are also expertly handled. 
  • Additionally, emerging technologies like UV-cured coatings and robotic or automated applications are being increasingly utilised, especially in large-scale or complex projects, ensuring consistent and high-quality application across diverse surfaces.

2. Repointing and Repairing Cracks

 

Repairing any visible damage to the brickwork, such as cracks or deteriorated pointing, is essential. This process involves removing the old, damaged mortar and replacing it with new, weather-resistant mortar. It’s a task that requires precision and should ideally be performed by professionals.

 

3. Improving Drainage and Guttering

 

Ensure that gutters and drainpipes are clean and in good condition. Regular maintenance to clear debris and repair any damage can prevent water from pooling and seeping into the brickwork.

 

4. Installing Damp Proof Courses

 

In some cases, the installation of a damp proof course (DPC) might be necessary, especially in older homes that may not have effective damp proofing. A DPC is a barrier designed to prevent moisture from rising through the walls from the ground.

 

5. Enhancing Ventilation

 

Improving the ventilation inside your home can reduce the risk of condensation, which in turn helps prevent water ingress. Simple measures like using dehumidifiers and ensuring good air circulation can make a significant difference.
