This week, our team completed a damp proof course after our initial damp survey uncovered the presence of rising damp within a property. Rising damp, if left unchecked, can escalate into a damaging and costly issue, posing potential hazards to both property and occupants. In response to our findings, we recommended a comprehensive damp proof course to eradicate existing damp and prevent future occurrences.
Understanding Damp Proofing:
Damp proofing is essential for safeguarding structures against moisture infiltration. Let’s delve into the steps involved in a damp proof course to mitigate rising damp effectively.
Step 1: Identification of Rising Damp:
The first step involves identifying rising damp on internal walls, indicating the upward movement of moisture from the ground. This serves as a clear indicator of rising damp originating from beneath the property.
Step 2: Injection of Damp Proofing Cream:
Holes are strategically drilled along the lowest accessible mortar line, approximately 110mm apart. Damp proofing cream, also known as DPC Cream, is then injected into these holes. This cream spreads through capillaries within the masonry, forming a barrier that prevents further moisture ascent.
Step 3: Application of Damp Proof Membrane:
Following injection and cleanup, a damp proof membrane is installed along the affected area, providing secondary protection against damp ingress into internal walls. This additional measure ensures a more durable damp proof system.
Step 4: Installation of Plasterboard:
Once the membrane is in place, plasterboard is dot and dab fixed over it. This process reinforces the structural integrity of the affected area.
Step 5: Skimming (Plastering) for Finishing:
After the plasterboard has hardened and all gaps have been filled, skimming or plastering is carried out to achieve a smooth, finished surface.
With the completion of the damp proof course, the property is effectively safeguarded against the detrimental effects of rising damp. Timely intervention and professional damp proofing are crucial in preserving the structural integrity and habitability of any property.
