Identifying problems to avoid bigger issues

Detailed Insight for Informed Decisions

The condition of a structure isn’t always obvious. Damage often starts beneath the surface, long before it becomes visible.

At H3 Construct, we carry out detailed, site-specific surveys to understand how concrete structures, coatings and waterproofing systems are performing in real conditions. The focus is on identifying deterioration early, understanding its cause and assessing the level of risk it presents.

Some surveys are carried out to inform refurbishment and upgrade works. Others respond to emerging issues such as water ingress, cracking or coating failure. Many are used to plan maintenance budgets and prioritise future works. In every case, the objective is the same: provide clear, usable information that supports confident decision-making.

Our experience working in live, occupied and high-risk environments means surveys are carried out without unnecessary disruption. From car parks and podium decks to commercial buildings and warehousing, we understand how to assess safely while operations continue.

We know what to look for, and where to look. Early signs of failure are often subtle and easily missed. Our surveys are designed to capture those details and present them clearly, so issues can be addressed before they escalate.

The outcome isn’t just a condition report. It’s a clearer picture of the asset, the risks it faces and the options available to manage it effectively.

  • What We Survey:

  • Concrete condition (spalling, cracking, delamination)

  • Structural movement and deformation

  • Failed or compromised coating systems

  • Waterproofing performance and drainage

  • Expansion joint deterioration

  • Signs of corrosion or chloride ingress

  • Surface defects and trip hazards

Drone Surveys

Accessing What Others Guess At

Not all defects are visible from ground level.

High-level soffits. Edge beams. Parapets. Movement joints. Roof decks. Façade interfaces.
These are often the areas where deterioration begins — and where traditional access is disruptive, expensive or delayed.

Our drone surveys allow us to assess critical structural elements safely, quickly and without installing scaffolding or closing operational areas.

Using high-resolution imaging and stabilised capture systems, we record detailed visual data of elevated and inaccessible areas across car parks, podium decks and commercial structures. This allows us to identify:

• Concrete cracking and spalling
• Rust staining and early corrosion indicators
• Coating breakdown
• Failed joints or sealant interfaces
• Drainage blockages
• Edge beam deterioration
• Membrane damage on exposed decks

But a drone survey is not just aerial photography.

It is part of a structured diagnostic process.

Captured imagery is reviewed alongside on-site inspections, previous reports and structural drawings. Where required, we correlate findings with chloride testing, carbonation depth analysis and intrusive investigations to build a complete understanding of condition and risk.

For asset managers, this provides:

• Rapid condition insight without disruptive access
• Safer inspection of high-risk areas
• Reduced preliminary cost before major refurbishment
• Clear visual records for reporting, budgeting and board-level decision making

Drone surveys are particularly valuable for:

• Multi-storey car park façades and soffits
• Edge protection and balustrades
• Roof-level decks and waterproofing systems
• Expansion joints across ramps
• Areas where MEWP or scaffold access would interrupt operations

The result is faster diagnosis, better-informed capital planning and fewer assumptions.

When managing a live, revenue-generating structure, insight without disruption is critical.

Drone surveys allow us to see the risk before it escalates — and plan intervention accordingly.
