Thebricks in this location have been badly eroded by rising damp and salt attack and are reaching the stage of deteriorationwhere structural instability is a risk.During the site visit painters were at work on the inside of the auditorium. The work being done, which included a“Bondcrete” sealant on the inside of the brickwork followed by coats of modern acrylic paint, will greatly exacerbatethe conditions which are damaging the brickwork. Again, a full description of the problem and possible solutions canbe found in the technical guide mentioned above.Site drainage is also of concern and its arrangement is exacerbating the brick deterioration and probably leading todeterioration to the flooring and framing timbers towards the front of the building (access was not available to checkthis).Masonry damage<strong>Council</strong>–owned buildings in StroudMay 2010
