As part of our maintenance works, if there are vertical cracks appearing on the external surface of a building due to movement in the structure, we carry out crack stitch repairs. This involves cutting out a recess in the wall placing a stainless steel helical bar and then infilling with a structural grout. The surface can then be made good.
Other works we carry out are wall tie installation when wall ties start to degrade and also large areas of brickwork replacement.
The above photos were taken from a contract in Southwick for Adur District Council housing, the flats where situated close to the sea and had been subjected to extreme weather conditions, causing spalling of brickwork in large areas and wall tie failure, we worked on this project 2013/2014.
