Little Salkeld Viaduct, also know as Dodds Mill Viaduct, is to be found in the Eden district of Cumbria, a few miles to the North-East of Penrith. The Viaduct consists of 7 arches, is 60 feet in height, and 134 yards long.
As part of Network Rails Asset Management strategy, the London North West route has experienced significant investment, in an effort to enhance, renew and maintain infrastructure. Works to little Salkeld Viaduct were carried out as part of this investment once Network Rail Asset Engineers had highlighted the need for brickwork enhancement works to each of the 7 spandrels forming the viaduct.
Specialist UK Restorations were appointed via AMCO Rail to carry out the works as per Network Rail Standard Design Drawings, and as outlined in the remit items of each detailed repair schedule. Due to the scaffold being erected to individual arches in stages and on pre-determined dates, it was paramount that we managed our workloads in line with the agreed programme.
As part of the brickwork enhancement remit, re-pointing was carried out to open joints throughout the spandrel walls, with areas of cracking and joint fractures undergoing stitch repairs and re-pointing as per Network Rail Standard Design Drawings NR/CIV/SD/101A, 106A & 107A.
The major element of the works consisted of several large areas of brickwork re-casing, as per NR/CIV/SD/101A & 103A. In certain locations spalling up to 190mm deep was evident, and in others the first course of arch rings had dropped noticeably.
