Carnousie Castle, Aberdeenshire

Carnousie Castle

Short History

Carnousie Castle is a late 16th century Z-plan three storey tower house with alternate round and square towers. The latter bears the date 1577. The castle has been greatly enlarged in the 18th century by an addition which did not interfere with the primary build.

After the last war the castle was abandoned and was being used as a pig sty when it was purchased and re-roofed. The extension was demolished and work began to restore the castle to its original 16th century appearance.

Today the castle is a private home owned by members of the Scottish Castles Association.


Just like in case of any old building, rising damp has been an ongoing problem. Although the castle owners did a great job during the years in restoring the castle to its fromer state, an all-encompassing solution for the handling of rising damp was not available before Aquapol.

After a detailed building survey the castle owner has decided to install the Aquapol masonry dehydration system. The system has been installed on the ground floor in the hallway in a more-or-less central location.

Several moisture control points have been chosen in order to be able to monitor the dehydration process. An initial set of measurements have been taken from the core of the masonry, these serve as reference values ot which all subsequent moisture measurements will be compared to.
