🟩 Rising Damp – South African Ground Moisture

Cause:

Occurs when ground moisture travels up through porous bricks or mortar, usually due to an absent or failed damp-proof course (DPC). This is especially common in older South African homes.

Signs to Look For:

• Peeling paint near floor level

• Salt deposits (efflorescence) on walls

• Crumbling skirting boards or plaster

🟦 Penetrating Damp – External Wall Entry

Cause:

Water enters through the exterior of a wall, usually due to cracks in rendering, porous bricks, damaged pointing, or leaky gutters and down-pipes.

Signs to Look For:

• Localized damp patches that worsen with rain

• Damp appearing mid-wall or ceiling level

• Peeling paint, bulging plaster, or black mould

• External signs: efflorescence or moss on walls

🟫 Condensation Damp – Poor Ventilation Warning

Cause:

Caused by warm, moist air hitting cold surfaces inside the home, often due to poor ventilation in kitchens, bathrooms, or laundry rooms.

Signs to Look For:

• Water droplets on windows or walls

• Black mould forming around corners or frames

• Musty odors that linger, especially after showers or cooking

• Damp concentrated in habitable living spaces, not just external walls

🟥 Lateral Damp – Horizontal Spread Near Basements

Cause:

Water travels sideways through a wall, usually due to external pressure from soil (in basements or retaining walls), or when the outside surface is not properly sealed.

Signs to Look For:

• Horizontal patches of moisture on mid-wall level

• No clear plumbing leak nearby

• Common near stairs, basements, or built-in planter boxes

• May appear even with gutters and roofs intact

Without the right expertise, damp can mask its true source, leading to costly misdiagnoses and ineffective repairs. That’s why a professional damp survey is essential. At Environmental Pro Construction, our surveyors don’t just treat the symptoms; we trace the problem to its root and design a solution tailored to your property’s unique conditions.

Recognizing the Signs of Damp

Damp doesn’t always show up where you'd expect, and by the time you see the signs, the damage may already be widespread. At Environmental Pro Construction, we help you spot the early red flags before structural issues or health hazards take hold. Common indicators like peeling paint, bubbling plaster, black mould, or discolored walls are never just cosmetic, they often signal deep-seated moisture infiltration that needs expert assessment and resolution.

🟩 Cracked, bubbling paint

This stairwell wall shows clear signs of moisture intrusion. The bubbling, cracked, and peeling paint is a classic symptom of trapped damp behind the plaster. Often caused by capillary action (rising damp) or lateral water movement from adjacent surfaces, this damage is more than cosmetic. If left untreated, it can compromise the structural integrity of both internal and external walls.

At Environmental Pro Construction, we don’t just treat the surface. We identify the source and implement a lasting solution using proven waterproofing and repair systems.

🟩 Damp Damage Behind Bathtub from Poor Sealing and Ventilation

Bathrooms are one of the most common areas for damp-related issues due to steam and water exposure. This image reveals plaster degradation behind a bathtub, caused by condensation, poor ventilation, and failed waterproofing at wall-floor junctions.

At Environmental Pro Construction, we apply moisture-zone-specific systems, including wall tanking, anti-mould treatments, and sealing to ensure long-term protection in wet areas.

🟩 Water Ingress on Concrete Ceiling with Efflorescence and Structural Staining

This image highlights water ingress through a concrete ceiling slab, often due to poor waterproofing above or cracks in the slab. The white efflorescence and dark stains indicate salt migration, which can corrode internal steel reinforcement over time.

At Environmental Pro Construction, we tackle slab damp with injection waterproofing, membrane systems, and structural repair solutions, always aligned with SANS 10400 standards.

🟩 Rising Damp on Interior Wall Near Skirting Line

This section of wall clearly shows signs of rising damp, a ground moisture issue that moves upward through capillary action when damp-proofing is compromised or absent. You’ll notice the discolored tide mark, crumbling paint, and salt blooms (efflorescence), all common with this type of damp. These areas are often mistaken for plumbing leaks, but the tell-tale line near the skirting is a giveaway.

🟩 External Wall Showing Combined Rising and Penetrating Damp

This exterior corner reveals dual signs of rising and penetrating damp. The darker blotches near the paving level point to moisture wicking up through capillary action, a clear case of rising damp aggravated by a compromised or missing DPC. Simultaneously, the concrete ramp at paving level likely allows rainwater to collect and absorb directly into the wall, leading to penetrating damp ingress.

🟩 Weather-Exposed External Wall with Moisture and Plaster Erosion

This external wall tells a clear story of prolonged water exposure and structural neglect. The discolored vertical runs, plaster delamination, and eroded facade highlight the effects of penetrating damp, combined with UV exposure and thermal expansion over time. The corner exposure and proximity to guttering make this wall highly vulnerable.

At Environmental Pro Construction, we resolve rising damp with targeted DPC injection, breathable plaster systems, and sub-floor drainage if required, always tailored to site-specific conditions and in line with SANS 10400 regulations.

At Environmental Pro Construction, we trace every route of water entry, from roof-line to foundation, and restore your external envelope with engineer-approved damp proofing solutions that last in South African conditions.

At Environmental Pro Construction, we address both ground-level causes and surface permeability using SANS 10400-compliant damp proofing techniques tailored for South African conditions.

This image reveals extensive black mould infestation caused by trapped humidity, poor ventilation, and inadequate waterproofing at ceiling level, often from above-floor damp or condensation build-up.

🟩 Severe Black Mould Growth on Bathroom Ceiling

Captured beneath a stair slab, this image shows rust leaching down the wall, clear evidence of water migration from structural steel above. This often indicates compromised slab waterproofing or slab edge failure, where moisture infiltrates and reacts with embedded re-bar or metal elements, causing oxidation.

This image captures plaster bubbling and surface blistering caused by trapped damp behind a curtain drop, an area prone to moisture retention due to limited airflow. These symptoms often result from lateral damp intrusion via cracked exterior walls, window sill leakage, or failed waterproofing at the roof-line.

🟩 Rust Streaks and Damp Patches from Slab Water Ingress

🟩 Wall Blistering Behind Curtain, Trapped Damp and Surface Breakdown

Mould like this isn’t just unsightly, it poses serious health risks and signals a deeper moisture issue.

Over time, this leads to wall staining, plaster decay, and concrete corrosion, which jeopardizes structural integrity.

At Environmental Pro Construction, we resolve such issues through advanced slab membrane systems, injection waterproofing, and structural sealing, all engineer-approved and aligned with SANS 10400 durability standards.

At Environmental Pro Construction, we don’t just remove the mould, we resolve the root causes through improved moisture barriers, anti-mould treatments, and SANS 10400-compliant waterproofing tailored for South African high-humidity zones.

The proximity to a window further suggests thermal bridging or inadequate sealing.

At Environmental Pro Construction, we trace these hidden pathways and resolve the issue using breathable plaster repairs, moisture-tolerant coatings, and tailored damp remediation, protecting both finishes and structure long-term.
