Geobear: Rapid Repairs for Flood and Water Damage

Geobear provides fast and effective emergency repair solutions for roads and buildings affected by washouts caused by flooding or water ingress. Our engineered geopolymer solutions address sinkholes, bowing pipes, subsidence, and slab failure, restoring stability and safety to affected sites.

Flooding and burst pipes are common causes of sinkholes and infrastructure failures. When water washes out sub-surface fill materials or soils, it creates voids that lead to structural problems. These can include sunken concrete floors in commercial facilities and hazardous voids or sinkholes beneath roads.

Our lightweight, structural geopolymer material is designed to fill voids and reinforce the surrounding ground. By injecting our geopolymer into both the void and the adjacent areas, we ensure the surrounding weak ground is stabilised, preventing future failures. Learn more about how we resolved a road void in Barnet using this method.

We specialise in emergency repairs for infrastructure and businesses, including logistics facilities that operate 24/7. Our solutions minimize disruption, allowing critical operations to continue with minimal downtime.

In addition to stabilizing ground and re-leveling sunken slabs inside buildings, we deliver fast ground injection works for roads, including access routes and port approaches.
