Case Study:
Comprehensive Damp Proofing and Cavity Wall Treatment

This case study details a recent job completed by G Jones Plastering & Damp Proofing, addressing a complex damp issue in a residential property. The problem stemmed from a combination of rising damp and insulation bridging the cavity wall, requiring a multi-faceted approach to resolve effectively.

The Problem and Diagnosis

Upon inspection, Gavin Jones identified two primary issues:

Rising damp due to a failing slate damp proof course (DPC)
Cavity wall insulation bridging, leading to moisture penetration

These issues were causing visible damp problems on the internal walls, potentially leading to further structural damage and health concerns if left untreated.

The Solution

Step 1: Cavity Wall Cleaning

Gavin began by removing bricks to access the cavity wall. He then meticulously cleared out the poorly installed insulation that was bridging the cavity, ensuring proper separation between the inner and outer walls.

Step 2: Chemical Injection

To address the failing slate DPC, Gavin injected a chemical damp proof course. This modern method creates an effective barrier against rising damp, supplementing the original slate DPC where it had failed.

Step 3: Fleece Membrane System Installation

Gavin installed a flex fleece membrane system to provide comprehensive damp proofing. This system offers several advantages:

Creates a physical barrier against moisture
Allows for easy plastering directly onto the membrane
Provides a smooth surface for finishing

Step 4: Plastering and Finishing

After installing the membrane, Gavin skilfully plastered over it, blending the new plaster seamlessly with the existing wall surfaces. This step ensures a uniform appearance and prepares the walls for painting once fully dried.

Step 5: Skirting Board Refitting

To complete the job, Gavin refitted the skirting boards. This not only restores the room's aesthetic but also provides an additional barrier against any residual ground-level moisture.

Outcome

The comprehensive treatment implemented by Gavin has effectively addressed both the rising damp and cavity insulation issues. The fleece membrane system, combined with the chemical injection, provides a robust defence against future damp problems. The seamless plastering work ensures that once painted, the walls will show no signs of the extensive work carried out.
