Extreme weather is not treated as a headline event in Contractors All Risk policies. It is treated as a mechanism of loss. Whether a claim succeeds depends less on what happened and more on how it happened, how long it happened, and whether it was sudden, unforeseen and accidental.
That distinction is critical.
Because when conditions turn, insurers do not only look at the damage. They look at the story of the risk.
When extremes hit construction
In South Africa’s construction industry, two realities have become impossible to ignore. Weather no longer follows neat calendars, and risk has become more unpredictable and more expensive to manage.
This is not theory. It is daily reality.
From flooding along our coasts and interior, to long dry spells that quietly change ground behaviour, environmental extremes are reshaping how projects are insured. For contractors, this affects pricing, conditions, and exclusions.
CAR insurance: broad cover, defined boundaries
Contractors All Risk insurance remains the backbone of construction risk management. It is designed to protect the contract works, temporary works, materials on site, and third-party liability arising from construction activities.
It is broad by design, but it is not limitless.
CAR policies respond to accidental loss or damage. Where weather exposure becomes ongoing, foreseeable, or inherent to the site, insurers begin to draw firmer lines.
Where water exposure can complicate claims
Flood is generally an insured peril. But not all water-related losses are treated equally.
Sites near rivers, wetlands, dams, coastal zones, or in low-lying ground often carry additional scrutiny. Ongoing groundwater ingress and continuous dewatering are commonly treated as operational conditions rather than insured events unless they are disclosed and agreed upfront.
In practical terms, this can mean:
-
- Pumping costs are often not recoverable
- Damage caused by failed dewatering may be challenged
- Claims depend on proving a specific triggering event, not a persistent condition
This is why contracts near or exposed to water are not automatically covered under standard terms and it’s important to let the insurer know. Disclosure is not red tape. It is protection.
Drought: the risk that rarely announces itself
Drought does not arrive with sirens. It shows up in ground movement, shrinkage, settlement and stress on foundations and temporary works.
Because these effects develop over time, they fall outside what CAR policies are designed to respond to. In simple terms, dry ground is not a peril. Only the consequences of a sudden failure might be.
The clause that quietly decides claims
Most CAR policies include a reasonable precautions condition. It expects contractors to anticipate foreseeable risks, maintain safe working conditions, and adapt when conditions change. After extreme weather losses, insurers ask practical questions: was flooding foreseeable, were drainage and pumping adequate, were drought impacts considered in method statements, and were engineers involved when conditions shifted? They also look at whether the Bill of Quantities and programme allowed for practical risk controls (like dewatering, stormwater management, protection of works, and ground stabilisation), and whether those controls were actually implemented and maintained. The answers shape the outcome.
Why this conversation matters
At CivilSure, we see the same pattern repeatedly. Claims do not unravel because contractors were reckless. They unravel because risks were assumed rather than discussed.
Insurance cannot remove environmental extremes. But early disclosure, clear advice and properly structured cover can stop uncertainty from becoming disruption.
Floods and droughts are not opposites. They are two edges of the same blade. And in construction, as in insurance, clarity always comes before control.
