Nordic Damp Proofing recently completed a full damp remediation project to a conservatory in Guildford, Hampshire, where moisture ingress had begun affecting the internal wall finishes due to a combination of raised external ground levels and the absence of an effective damp proof course.
Following our detailed survey, we carried out both internal and external remedial works to eliminate the source of the damp, isolate the affected masonry and protect the property for years to come.
The project included a new chemical damp proof course, external drainage improvements, breathable masonry protection and a full internal damp proof membrane system, all backed by our long-term guarantee.
Diagnosing the Cause of the Damp
Our inspection identified moisture tracking into the conservatory wall from ground level.
Due to the angle and construction of the conservatory, there was no effective damp-proof course protecting this section of masonry. Over time, moisture had been drawn into the wall, contaminating the plaster with hygroscopic salts and causing deterioration to the internal finishes.
Rather than simply replastering the affected area, we treated both the cause and the visible damage to provide a permanent solution.
Internal Damp Treatment
The first stage of the work involved removing all contaminated plaster back to the original masonry.
This exposed the wall and allowed us to install a complete damp-proofing system designed to prevent future moisture migration.
The treatment included:
- Removal of all damp-contaminated plaster
- Injection of a specialist chemical damp proof course
- Application of a waterproof damp proof membrane
- Professional replastering using a renovating plaster system suitable for damp-affected masonry
The new membrane isolates any remaining moisture and hygroscopic salts within the wall while providing the ideal base for the new plaster finish.
External Groundworks & Drainage Improvements
To ensure the problem would not return, we also completed remedial works externally.
A perimeter drainage trench approximately 1.8 metres long was excavated alongside the affected wall. The trench was then filled with clean free-draining shingle to reduce moisture build-up against the brickwork and encourage rainwater to disperse away from the property.
Because this section of the conservatory could not accommodate a traditional physical damp proof course, we installed a specialist chemical damp proof course externally to create an effective moisture barrier within the wall itself.
Finally, the brickwork received a breathable clear masonry cream treatment, helping to repel driving rain while still allowing trapped moisture within the wall to evaporate naturally.
The Finished Result
With both the internal and external works completed, the affected corner has now been fully protected against rising moisture.
The homeowner now benefits from:
- A new chemical damp proof course
- Waterproof internal membrane protection
- Fresh replastered finishes
- Improved external drainage
- Breathable masonry protection
- Long-term protection against future damp problems
Treating both the source of moisture and the internal damage provides a far more reliable solution than cosmetic repairs alone.
