remedial expansion joints
AWT recognised that the ability to introduce remedial expansion joints was a necessary part of our repair strategies and set about facilitating this requirement.
In large areas of brickwork constructed without the benifit of an exspansion joints the introduction of remedial expansion joints has been recognised as one of the most effective solutions to address cracking to brickwork due to seasonal thermal expansion and contraction (hygrothermal) that is not attributable to significant subsidence.
AWT have extensive experience introducing remedial expansion joints and have invested much time and money in developing repair strategies that are both effective and respectful of the building to which they are being applied.


AWT have carried out comprehensive testing and development of equipment and methods to facilitate the cutting of remedial expansion joints.By adopting Hydraulic powered twin bladed diamond disc and diamond chain saws all with special guides AWT are able to cut straight, wide parallel joints into existing brickwork (up to 325mm thick) in one pass to form expansion or crack-inducement joints.
Common applications are to cut through the full depth of the external half-brick skin of cavity walls, the external half-brick skin of solid constructed walls and a full 225mm width of parapet walls.


AWT operatives are highly skilled in traditional building methods and always attempt to match replacement bricks, pointing styles and mortar colour to be sympathetic with the existing building. Our role is to preserve not just the integrity of the building but its aesthetic qualities for future generations to admire.
