Drum Castle is a Category A Listed building dating from the 13th century. The original Keep or Tower House is one of the oldest in Scotland, complete with 70ft high solid masonry walls and finished with corbelled battlements. The large Jacobean mansion was added in 1619, with further alterations during the Victorian era. The result is an amalgam of architectural styles culminating in one of Scotland’s most dramatic castles.
Scope of Work
LTM were contracted by the National Trust for Scotland to solve the problem of water ingress at the battlement walls and roof slabs, which was causing internal dampness through the mass masonry walls at the lower levels of the tower.
Works included: dislodged battlement coping stones were recorded, uplifted and re-bedded; wall core consolidated using broken clay tile, hammered into mortar filled joints to ensure maximum compaction and flush pointed over to reduce water penetration; removal of failed cement mortars and replaced with traditional lime mortars; replacement of concrete drain using Caithness slab with integrated carved water outlet; Caithness slate indents were carved on-site to replace all fractured, laminated and eroded slabs.
