Tyne Tunnel

We developed a unique ready-mixed concrete product to create a new river tunnel as well as provide material to support the refurbishment of an existing vehicle tunnel. The entire project involved sixteen seperate 580 cubic metre pours - with the concrete pump being fed constantly, lasting up to 18 hours in total. 

The tunnel segments were manufactured on the banks of the river with technical support provided to overcome challenging issues such as thermal cracking and chloride ion ingress.
