The series of photographs below illustrate an example of a before and after Crack Stitch installation used in conjunction with Masonry Beam to return structural integrity to a crack brick wall caused by root ingress from a climbing ivy that was allowed to get out of control.
Photographs below illustrate an internal crack repair to walls and plaster finishes. The parent structural element of these walls are or circa 19th Century vintage constructed in a combination of random flints and soft Norfolk red bricks within a lime mortar matrix. The property had been updated and modernised internally in the 1980's using modern gypsum plaster finishes. Some movement had taken place in the interim period due to leaking drainage problems leading leading to cracks around weak points such as windows. As the 1980's modernisation had used gypsum plaster we used the same to make good wall chases and the like, although more sypathetic lime plaster materials could have been used if required.
The series of photographs below illlustrate the structural reinforcement and repair of a 1990's property suffering from cracks caused by thermal movement of a south facing wall. damage was localised to the top half of one corner hence a Crack Stitch repair was specified rether than a full height Movement Joint.
From an environmental, economic and aesthetic perspective the Thor Helical system is quick to install, thus reducing on site time; minimizes waste by retaining large sections of a building that would have traditionally been replaced, and retains the original fabric of a building where masonry may be difficult to match.
