Topbond Group

Topbond Group is a civil engineering contractor with a strong presence in the water and environment sector, known for its innovation and high-quality service. The company has expanded its presence in East Anglia, growing both in staff and operational capacity. A notable project was addressing recurring flooding along the A47 near Honingham, Norfolk, where heavy rainfall had caused significant disruptions. Topbond, acting as principal designer and contractor, identified that the drainage system was silted and reduced in capacity. The company quickly designed and installed two 91,000-litre settlement tanks to allow sediment-laden stormwater to settle before entering the drainage network and discharging into the River Tud. The tanks were installed in just seven months, overcoming challenges such as soft soils and high groundwater levels. The solution also included remote monitoring to ensure long-term effectiveness, reducing sediment and oil runoff and benefiting both the environment and the local community.
