Our Free And Live CPD Webinars

Our live webinars are free to join and will give you an understanding of geopolymer engineering and its application across various sectors. Please use the links below to sign up.

November 21 - 12:00 - Residential Subsidence and Geobear Solutions

Houses are prone to movement; subsidence is one of the most common structural issues affecting UK homes, often linked to clay soil shrinkage during dry weather but also seen in properties built on granular ground. This webinar provides a clear overview of how and why subsidence occurs, the visible signs for homeowners, and the risks if left untreated. We’ll also explain how Geobear’s innovative geopolymer injection technology works across both clay and granular soil scenarios, offering a fast, non-disruptive and proven alternative to traditional underpinning.

December 12 - 12:00 - Infrastructure Assets and Geobear Solutions

From roads and railways to airports and tunnels, ground movement and deterioration can shorten the lifespan of critical infrastructure. This webinar explores how geopolymer injection technology is being used to extend asset life, reduce disruption, and deliver significant carbon savings compared to conventional methods. Featuring case studies including the Blackheath Tunnel, Chapel Milton Viaduct, A10 concrete bay stabilisation, and major airport runway repairs, we’ll show how Geobear provides rapid, sustainable solutions that keep the UK’s infrastructure moving.
