M25 tunnel refurbishment uses Ronabond Concrete Cover 150



Ronabond Cover Plus 150, now called Ronabond Concrete Cover 150, played a part in a major project to improve traffic flow and safety on the M25 near Waltham Cross; a busy stretch of road taking 120,000 vehicles daily.

The £75 million project involved adding extra lanes to the Holmesdale Tunnel and upgrading lighting, ventilation, incident detection systems and CCTV in the tunnel. An extra lane was also added to the M25 eastbound through junction 25.

Part of the widening scheme involved partial removal of concrete, exposing steel reinforcement. Ronabond Cover Plus 150 was used to coat the concrete and exposed steel, thus returning reinforcement cover.
