This project involved treating persistent damp issues affecting a recessed doorway area within a property in Reading.
The original wall had suffered from moisture contamination, resulting in visible damp staining, deterioration of internal finishes and ongoing moisture concerns around the lower section of the wall.
Following a detailed inspection, our team recommended installing a damp proof membrane (DPM) system to isolate the affected masonry before replastering and restoring the area.
Investigating the Damp Problem
The affected wall was located within a recessed entrance area where moisture had been affecting the internal masonry and decorative finishes.
Signs of damp included:
• Damp staining to lower wall sections
• Deteriorating plaster finishes
• Moisture contamination within the masonry
• Historic salt contamination from previous dampness
• Ongoing concerns about future decoration failure
To provide a long-term solution, the existing affected finishes were removed and the wall prepared for treatment.
Installation of a Damp Proof Membrane System
To prevent residual moisture affecting the new finish, a damp proof membrane system was installed across the affected area.
The system creates a separation between the damp masonry and the internal decorative finish, helping prevent future issues caused by moisture migration through the wall.
Works included:
• Preparation of the existing substrate
• Installation of damp proof membrane protection
• Mechanical fixing of the membrane system
• Formation of a new surface ready for finishing
• Preparation for replastering
This approach provides a durable and reliable solution where damp contamination has affected internal walls.
Replastering & Restoration
Once the membrane system had been installed, the wall was professionally replastered to provide a smooth finish ready for decoration.
Care was taken to maintain the character of the surrounding brickwork and arched doorway features while creating a clean, modern finish.
The completed result provides:
• A dry internal wall surface
• Protection against future moisture transfer
• Improved appearance of the entrance area
• A finish ready for decorating
• Long-term damp management
Why Use a Damp Proof Membrane System?
Damp proof membrane systems are often recommended where traditional plaster has become contaminated by moisture and salts.
Benefits include:
• Separates damp masonry from internal finishes
• Reduces the risk of future plaster failure
• Helps prevent salt contamination reaching decorations
• Creates a dry surface ready for finishing
• Long-lasting and effective damp management solution
When installed correctly, a membrane system can significantly improve the performance and appearance of damp-affected walls.
