Damp that keeps coming back has been treated at the wrong point. Every treatment that fails is another levy-funded repair that did not last. The correct approach identifies the moisture pathway and closes it, not just the staining it leaves behind.
The most common reason damp treatment fails is that it addressed the visible symptom, not the source. Applying a moisture-resistant paint to a damp wall will look fine for a season and fail when the wall's moisture content rises again. The pathway feeding the moisture into the wall stays intact. Effective treatment finds the pathway and closes it, whether that is a failed damp proof course, a gap in the external envelope, drainage directing water toward the building, or a retaining wall with no tanking behind it.
Rising damp is groundwater drawn upward through masonry by capillary action, typically appearing as a horizontal band of staining, salting or plaster deterioration low on an internal wall. It indicates a failed or absent damp proof course. Treatment usually involves a chemical injection system to create a new damp proof barrier in the wall, followed by re-plastering with a salt-resistant plaster where the existing plaster is contaminated.
Lateral damp enters horizontally, often from a boundary wall in contact with soil, a retaining structure, or through gaps and failures in the external building envelope. It can appear at any height on a wall rather than just at the base. Treatment depends on the source: external tanking, drainage improvement, cavity installation, or sealing of the external face. For below-ground structures, see basement tanking.
Effective damp treatment starts with a proper assessment. A damp meter reading confirms moisture presence and extent; visual inspection identifies the likely pathway; understanding the building's age and construction method narrows the cause. The treatment is specified once the source is understood, not before. For an older Johannesburg building from the 1950s to 1980s, a failed damp proof course at the base of brick walls is the most common finding.
Recurring damp complaints in a sectional title scheme are one of the most common reasons trustees face criticism at an AGM: money was spent, the problem came back, and it was not clear what was done. Sky Rig quotes damp treatment with a written scope that describes what was found, what will be done, and why it will last, structured for trustee sign-off and suitable for the body corporate's records. Work is carried out with minimal disruption; most injection and crystalline systems have low-odour profiles and do not require occupants to vacate. Sky Rig is SANS 10333 compliant and OHSA Section 37 documentation is ready before mobilisation. Where any ventilation or access consideration applies, it is flagged at the assessment stage before work starts.
Send us the details and we will assess the cause, not just the symptom, and quote a treatment that actually closes the moisture pathway rather than painting over it.
Rising damp draws groundwater up through masonry by capillary action and typically appears as a band of staining or salting low on an internal wall. Lateral damp enters horizontally from a boundary wall, a retaining structure or through gaps in the building envelope at any height. The treatment method differs significantly between them, which is why diagnosis comes first.
