Norwich International Airport is a WWII airport with flint concrete slabs which have been layered with bitumen every 10 years creating a 250-300mm overlay. The slabs have broken in places with reflections of the breaks showing through the bitumen causing dropped sections on the surface of the runway. Canham Engineering identified 3 major sections where the sub-base was still moving causing problems at the surface. Due to the urgency of the programme Colas were only able to provide DWG Resins with a week to mobilise and commence work on site. This schedule was adhered to and all works were completed in a prompt and professional manner. DWG Resins were brought in to stabilise & re-support the existing concrete slabs negating the requirement for disruptive excavations.
