Case studies

Rising & Penetrating Dampness


 The initial enquiry from the owner of the property was in connection with several damp patches on  one of the external ground floor bedroom walls. We had already carried out some damp proofing works to other areas of the property nearly 20 years ago.


Other areas of walls, skirting boards and floor timbers where tested for dampness using an electronic moisture meter.  High readings were obtained both at low and high levels. This prompted a sub floor inspection which revealed a damp unsealed solum area, wet rot to wall-plates and joist ends. Debris was also noted trapped between the external stone walls and lath & plaster walls, which in turn was transferring dampness onto wall plaster internally. No physical sign of a damp proof course was evident.


The damp problems and decay in this property have been caused by a combination penetrating & rising damp, which in turn has resulted in wet rot attacks to unprotected wall strapping, timber safe lintels and floor timbers.  It should be noted that this problem is typical to older farm type buildings around 100 years old and is more to do with building practices of that  time.


The worst effected wall was stripped full height, with all other walls being stripped up to a height of 1.2 meters. All floor timbers were removed totally. The solum area was cleared of debris and sub-floor walls made good. A chemical damp proof course was installed just below floor level around the entire room, both internally and externally. The solum was sealed with DPM and concrete prior to new wall-plates, joists and floor boards being fitted. Exposed walls were strapped, ensuring they were isolated from the external stone work, sheeted with plaster board and finished with a skim coat of plaster.

End Result

The client has been left with the peace of mind that the root cause of the dampness was identified  along with the additional problems, which if left unattended could have resulted in major problems in the future.
