The stone wall along the Cootehill Road boundary of the Rossmore Estate in Monaghan was in very poor condition. The aggressive root system of a Wych Elm tree had loosened or dislodged almost all of the coping stones to the top of the wall, and water was making it into the centre of the wall, undermining the corefill and causing more stones to 'pop' out of the wall. The wash from passing traffic to the roadside face was also undermining what was left of the original pointing and the wall had collapsed in two sections.
Fortunately, enough stones were salvaged from the site to re-construct the collapsed sections and to reinstate the coping stones. A significant amount of lime mortar was required to reinforce the core of the wall in addition to re-pointing. We enjoyed working closely with Noel Carney of Rossmore Mausoleum Conservation Group during the project, and Phase 1 (the conservation works to the western side of the wall) was completed late 2014
