When Water Starts to Win: Signs Your Structure May Be at Risk

With heavy rains, water damage may become and issue for your building. This is one of the most common, and most overlooked, causes of structural deterioration.

Here are a few visible signs that could indicate water-related structural issues:

• Cracks in walls or columns: Moisture can weaken materials or cause foundation movement.

• Stalactites and Efflorescence: Water transferring through concrete slabs and columns typically results in early defect signs.

• Ponding of water: Ponding water can become a major issue if not dealt with or may be signs of weakening slabs.

• Warped floors or ceilings: Swelling or distortion in finishes/timber often points to hidden moisture.

• Musty or earthy odours: A strong indicator of trapped dampness, mould or material decay.

• Foundation movement: Shifting or bowing walls are often linked to changes in soil moisture.

If you notice any of these signs, it’s worth arranging a structural audit before the damage worsens. Identifying early signs of deterioration can prevent major repair costs and ensure ongoing safety and compliance.

We carry out detailed structural audits to assess condition, identify risks, and recommend the right remedial actions.

Our drone surveying services include full topographical studies that include point clouds, accurate height models, and detailed land surveys for both greenfield and brownfield sites.

Using advanced technology, we can cover areas of up to two hundred hectares.

Our drones also support thermal scans and structural audit investigations. Once the data is captured, we analyse it to identify structural concerns, performance issues, or site constraints, and provide clear engineering assessments based on what we find.

Whether you’re preparing for new development, expansion, or maintenance planning, precise aerial data ensures you make informed decisions from day one.

As the year enters the final stages, it’s the right time to start planning ahead, especially when it comes to the integrity and compliance of your commercial or industrial buildings.

A structural audit plays a critical role in understanding the true condition of your property and ensuring it’s ready for the year ahead. These audits are essential at key points in a building’s lifecycle, including:

• Change of ownership or management – Ensures new owners understand the structure’s current condition.

• Routine maintenance cycles – Identifies wear, tear, and emerging issues before they escalate.

• Before renovations or upgrades – Confirms the structure can support planned changes, including solar installations.

• After significant events – Assesses any damage from extreme weather or incidents that may affect structural integrity.

• Legal or insurance requirements – Provides compliance assurance where an audit is required by regulation or policy.

Solar power is a major source of renewable energy for commercial, industrial and residential buildings. Before installation, it’s important to know that your existing structure can support the solar system. Our structural audits are conducted by qualified structural engineers and our reports are verified and compiled by a professionally registered engineer with SAICE and ECSA.

Our green design service consists of:

• Thermal drone inspections for damages, debris and losses
• Visual and/or comprehensive structural defects
• Visual and NDT detection of structural defects, damages, distress, deformation or deterioration
• Verification of load conditions
• Wind load analysis
• Carport structure design
• Assessment of current conditions and suggestions for appropriate remedial action
• Design of new solar structures

In a structural audit for a client, we assessed areas of their building where water leaking through concrete slabs causing efflorescence to form on the soffit of the slab.

This could lead to corroding rebar, spalling concrete and considerable risk if not attended to.

We’re approaching the storm season and with the rise of unpredictable weather events, the importance of structural integrity has never been more critical. In recent years, we’ve seen excess rainwater, high winds, hail, extreme heat, and other environmental impacts in ways we haven’t faced before and some structures are not prepared for it.

Why a Structural Audit? A structural audit helps identify potential risks and defects before they become costly hazards. By assessing a building’s resilience, you reduce the chances of sudden safety issues and prevent major financial setbacks in the event of structural failure.

A structural audit is not only something to consider when there is a visible problem. There are several important points in a building’s lifecycle when understanding its structural condition can help manage risk and avoid costly problems.

• Change of ownership or management: Understand the condition of the building before taking responsibility for it.

• Regular maintenance: Periodic audits can identify wear, deterioration and other issues before they become more serious.

• Renovations or upgrades: Before making significant changes, confirm that the existing structure can support the proposed work. This includes solar system installations.

• After significant events: Extreme weather, natural events or incidents can affect structural integrity and may warrant an assessment.

• Legal or insurance requirements: In some circumstances, structural assessments may be required to demonstrate compliance or support insurance requirements.

A structural audit provides a clearer understanding of the condition of your building and helps you make informed decisions about maintenance, upgrades and ongoing use.

It’s important to evaluate the latest materials to ensure safety, efficiency and sustainability in construction. Lightweight building materials are gaining popularity, so it’s crucial to consider some benefits and challenges.

Benefits:

• Reduced Dead Load: Lighter components lessen the load on foundations, enabling simpler footings and potential cost savings.

• Faster Construction: Prefabricated panels and sections are easier to handle and install, accelerating build programmes and reducing labour demands.

• Improved Thermal Performance: Many lightweight materials offer excellent insulation properties, cutting energy consumption and enhancing comfort.

• Sustainability: Engineered timber and recyclable composites lower embodied carbon, helping projects meet green-building targets.

Challenges:

• Structural Stiffness: Lighter materials can deflect more under load. Careful design and connection detailing are essential to control movement and vibration.

• Fire Resistance: Some lightweight products need additional fire-protection measures or coatings to achieve required fire ratings.

• Durability & Moisture: Engineered timber and composites may be sensitive to moisture or UV exposure; proper sealing and maintenance are critical.

• Cost Premium: Advanced composites and treated timber can carry higher upfront costs, though lifecycle savings often offset initial investment.

Through our structural audits, we assess existing frameworks to determine suitability for lightweight solutions, identify potential deflection or connection issues, and recommend remedial strengthening where needed.
