The RBAI, or Inst, as it is locally better known as, is one of the finest examples of late Georgian architecture in Ireland, and dates back to 1810. Stronghold Preservation were requested to survey and carry out treatment for damp and timber rot in the North Wing of the school. The building is constructed from clay brick with solid ground floors, suspended timber first and second floors.
Damp and wet rot was discovered on the ground and first floors.
Further Information
Damp Proofing
From our survey, it was discovered that ground levels were
higher than finished floor levels, allowing lateral penetration of
ground water. An electro osmotic damp
proof course was installed to prevent damp rising up the
walls. A tanking
solution (cementitious waterproof membrane) was also applied below
the dpc to prevent water transfer below the damp proof course, due
to the high ground levels.
Wet rot
Timber plugs were found embedded in the damp masonry, resulting
in wet rot.
These timbers were removed, and replaced with masonry. Timber
floor joists bedded in the walls also had high moisture
readings. The joist ends were treated with a boron
preservative to help provide a long lasting action against
fungal decay (dry rot).
