For most manufacturers and users of pre-cast concrete culverts in South Africa, climate-ready materials have not been a major consideration. However, as Cobro Concrete has been anticipating for quite some time, climate-ready culverts are soon set to become the industry standard. Here’s why.

Shifting Standards in Culvert Engineering

Climate-ready culverts are transforming from niche engineering projects into a non-negotiable standard. As engineers find that infrastructure faces heavier challenges from intensified, climate-change-induced flooding, extreme weather, and altered water flows, they are increasingly turning to climate-ready culverts for use in their projects. These structures are designed to manage higher volumes of water, reduce the risk of structural failure, and ensure long-term sustainability of transportation networks and other infrastructure.

Why the Shift in Standards?

In light of the change in demand that has resulted from climate change and its consequences, engineering standards have also started to shift. When assessing the need to cope with higher chances of flooding and manage larger volumes of flood water, engineers are starting to plan their projects by different standards:

  • From Reactive to Proactive: Traditional design, based solely on past hydrological data, is being replaced by forward-looking, risk-based methodologies.
  • Sustainability Now a Primary Concern: By 2026, sustainability is no longer just a project-level consideration but the organizing principle, integrating economic, environmental, and social needs.
  • Flexibility and Adaptability: Given the high uncertainty of future climate scenarios, infrastructure design is increasingly emphasizing adaptability, ensuring that when, or if, failure occurs, the consequences are minimized.

What Do Engineers Expect from Climate-Ready Culverts?

Climate-ready culvert standards include the following considerations:

  • Increased hydraulic capacity: Culverts are now designed to allow them to accommodate 10-20% increases in precipitation.
  • Environmental integration: Modern culverts are designed for habitat connectivity and to allow the movement of fish and other aquatic animals. These designs help to prevent ecological damage.
  • Smart design: Advanced modelling helps designers to pre-empt failures, such as overtopping, sediment or debris flow, and engineer their culverts accordingly.
  • Lifecycle Cost-effectiveness: Climate-ready culverts are sometimes higher in initial cost, but being designed for resilience and longevity, they provide significant long-term savings.
