Скачать или смотреть UNDERGROUND UNCERTAINTY — Dolomite Risk, Property & Protection in the Centurion Area

South Africa’s dolomite-rich soils, especially in Centurion, Lyttelton and surrounding Gauteng suburbs, are no longer just a geological curiosity.

After a summer of exceptional rains, groundwater movement and water ingress have triggered an increase in sinkholes and ground subsidence, posing real challenges for homeowners, buyers, developers and insurers alike.

Join us live this Thursday as we unpack:

✔ Why dolomite ground becomes unstable and what heavy rains (or fluctuating groundwater) mean for your land and structures;

✔ What recent events and sinkhole incidents in Centurion tell us about current and future risk;

✔ How insurance works (and sometimes doesn’t) in these high-risk areas;

✔ What property buyers, owners and developers need to know before a sale, a build or a renewal.

Featured Speakers:

🎙️ Marna Roets — Insurance specialist, Inscorp Insurance Brokers (expert on dolomite-related cover and claims)

🎙️ Aubrey de Beer — Engineering Geologist, ADB Engineering Geology (expert on dolomite formation, ground risk and mitigation)

Whether you own a home, are considering buying property, are involved in property development, or want to protect your investment — this conversation is practical, urgent and local.

📌 Why This Matters Now

With recent excessive summer rains across Gauteng, sinkholes have been forming or reactivating, especially where dolomitic rock lies close to the surface (as in Centurion).

In Tshwane alone, more than 60 sinkholes have been recorded — and heavy water influx has been linked to new collapses — underscoring the need for preparedness and informed decisions.
