Rising damp of ground water in masonry brick walls is a frequently observed phenomenon in
historical buildings. It can lead to structural and material failures, as well as to mold growth and
indoor air quality problems. The insertion of impermeable materials into damp wall is
considered to be amongst the more effective measures to stop the water ingress from the ground.
This paper presents the results of a computational hygro-thermal study on rising damp. The
study concerns the interior and exterior brick walls of a historical church building in a hothumid
climate (Thailand), which displays moisture problems. The results suggest that the
cutting wall measure as rising damp treatment can reduce water content (as compared to the
pre-retrofit condition) up to 90% in interior walls and up to 40% in exterior walls. Thereby,
water content levels drop down to a steady level within two years after the intervention.
