Flexcrete was chosen for a £1.65 million viaduct refurbishment in Centenary Way Viaduct in Burnley.
The Centenary Way viaduct is a critical part of Burnley’s road network, supporting movement in and out of Burnley. The seven-span continuous viaduct is 193 metres in length and carries the A682 which provides the most direct route from the M65 motorway to a number of key sites in the town centre.
A £1.65 million refurbishment scheme was carried out, including concrete repairs, work to the bearings and joints, parapet repainting, deck waterproofing, carriageway and footway resurfacing, to enable the viaduct to be reopened to abnormal loads vehicles.
The major problem that needed to be rectified was the defective bridge bearings and Monopour PC6 micro-concrete was specified to fill the voids.
As a result of chloride ion ingress from de-icing salts, the concrete on various elements of the viaduct was spalling away, leaving exposed corroded steel reinforcement. Fastfill, a rapid setting repair mortar, was used for repairs to the deck of the viaduct and to fill in any holes.
Monomix HD, a high strength, waterproof repair mortar, was specified for repairs to the underside of the deck.
The rapid and easy application of Flexcrete materials was important for this project, so as to cause minimal disruption to the road network.
