Preserving the Integrity and Safety of Your Building

Structural and spalling repairs are essential components of any comprehensive building maintenance strategy. At Indawo, we understand the critical importance of maintaining the structural integrity of a building, from foundation to rooftop -ensuring long-term safety, functionality, and value.

Expert Repairs in Cape Town’s Challenging Climate

Operating throughout Cape Town and the Western Cape, Indawo provides a full range of structural and spalling repair services tailored to the region’s unique environmental challenges. Coastal conditions, including persistent sea spray, high humidity, and extended winter rainfall, significantly increase the risk of spalling - especially in high-rise and older buildings.

The Dangers of Structural and Spalling Damage
• Structural damage may lead to partial or complete building collapse.
• Spalling, if left unchecked, can compromise the structural framework.
• Delays in addressing damage lead to escalating repair costs.
• Water ingress, often due to failed waterproofing or ageing materials, is the primary cause of spalling.

What is Spalling?

Spalling occurs when water penetrates the outer surface of a building and reaches the steel reinforcement (rebar) inside. This moisture causes the steel to rust and expand, leading to cracks, flaking plaster, exposed bricks, and even compromised concrete structures. Over time, these issues become both structurally dangerous and visually deteriorative.

Signs of spalling include:
• Hairline or widening wall cracks
• Rust stains on exterior walls
• Flaking or peeling plaster
• Brick splitting or surface crumbling

Preventing Spalling

Prevention starts with proper waterproofing and the correct selection and application of coatings and paints. Many spalling issues stem from:

• Ageing exterior finishes
• Incorrect product application
• Use of non-compliant or substandard materials

Moisture that infiltrates the structure can go unnoticed for years before visible damage appears—by then, the repair costs are significantly higher.
