Understanding the Effects of Damp
on Brickwork and Stonework
Dampness in brick and stone structures is a common problem that can lead to significant structural and aesthetic issues if not addressed promptly. Moisture intrusion can result from various factors, including poor drainage, weather conditions, and material quality.
Understanding the causes of dampness, its effects, and effective prevention and remediation strategies is essential for maintaining the integrity and appearance of your brick and stonework.
Causes of Dampness in Brick and Stonework
1. Poor Drainage:
Inefficient drainage systems can lead to water pooling near brick and stone surfaces. Clogged gutters, downspouts, or inadequate grading can exacerbate moisture issues.
2. Rising Damp:
Groundwater can rise through capillary action in the masonry, especially in older buildings without proper damp-proofing. This phenomenon is known as rising damp.
3. Driving Rain:
Wind-driven rain can penetrate unprotected masonry, especially if the surface is porous or damaged. Poorly sealed joints and cracks can also allow moisture to enter.
4. Condensation:
High humidity levels indoors can lead to condensation on cool masonry surfaces. This is particularly common in basements or poorly ventilated areas.
5. Leaking Pipes:
Internal plumbing issues or leaks from fixtures can contribute to dampness in brick and stone structures. Water from leaks can seep into the masonry, leading to moisture problems.

4. Address Rising Damp
Here’s a step-by-step guide on how to effectively cure dampness in masonry:
1. Identify the Source of Dampness
- Conduct a Thorough Inspection: Begin by assessing the affected areas for visible signs of dampness, such as discolouration, efflorescence (white powdery deposits), and peeling paint.
- Check for Water Ingress: Investigate potential sources of water infiltration, including leaking gutters, damaged roofing, cracked walls, or rising damp from the ground.
- Evaluate Interior Humidity: High indoor humidity levels can also contribute to dampness. Use a hygrometer to measure humidity levels and identify potential indoor sources of moisture.
2. Improve Drainage and External Conditions
- Clear Gutters and Downspouts: Ensure that gutters and downspouts are clean and functioning properly. Clogged gutters can cause water to overflow and pool near the foundation, leading to dampness.
- Landscape Grading: Adjust the grading around your property to slope away from brick and stone surfaces. This will help direct water away from the foundation and reduce moisture accumulation.
- Install Drainage Systems: Consider installing French drains or other drainage systems to divert water away from the masonry. Proper drainage is key to preventing dampness.
3. Repair Structural Issues
- Seal Cracks and Joints: Inspect brick and stone surfaces for cracks or damaged mortar joints. Use appropriate sealants to fill in gaps and prevent water from entering.
- Repoint Mortar Joints: If mortar joints are deteriorating, repoint them using a suitable mortar mix that matches the existing material. Properly sealed joints will enhance the durability of your masonry.
4. Address Rising Damp
- Install Damp-Proofing Solutions: For rising damp issues, consider applying a damp-proof membrane or barrier to the affected areas. This will help prevent moisture from migrating upward through the masonry.
- Use Damp-Proofing Injection Creams: In some cases, damp-proofing injection creams can be used to create a barrier against moisture rising from the ground.
5. Improve Ventilation
6. Clean and Treat Affected Areas
7. Apply Protective Treatments
