The Gateshead Interchange, Tyne & Wear
Work is made possible by a combination of scaffolds, towers and cradles.
Masonry beams were installed to relieve the loadings on the arched lintels. Diamond drilled holes were made to avoid spalling of the brick faces and helical fixings were installed through the splayed face of the soldier course to tie back the masonry into the inner leaf.
A Helical Bar is introduced to the slots 'chased' out of the masonry.
The Helical Bar is grouted into position.
There are no visible signs that the masonry has been reinforced.
High wind loads to the parapet walls, together with inadequate bearings of the arched brick lintels made the likelihood of falling masonry a real possibility. Using cradle access, we stabilised the parapet walls and re-fixed the arched brick lintels using Helical Bar technology.
