Causes, Investigation & Repair

» Qualified for 7 PDUs by PE Board


Dampness and Leaks are prolific building defects and account for over half of the investigations into building defects. Dampness adversely affects living/working conditions and the health of building occupants; the resultant damage to materials and structure can lead to considerable costs in remedial works.

Common regional construction techniques such as the use of half brick external panel walls to multi-storey framed buildings; the inadequacy of damp/water proofing barriers in walls/floors/roofs have led to many dampness complaints. Tracing the source of dampness and leaks requires careful diagnosis and a thorough understanding of the physical and chemical principles involved.


The specific objectives of the course are to:

  • Recognise Different Types of Dampness and Relate them to the Source of Moisture
  • Understand the Effects of Moisture on Material and Component Performance
  • Appreciate Procedures for Investigating Dampness and Instrumentation Involved
  • Learn Materials and Methods of Repairing/Resolving Dampness and Leaks in Buildings.

Dr Quah Lee Kiang FRICS

Dr Quah is the Director of the Real Estate & Construction Centre and the Real Estate & Construction Academy in Singapore. She has extensive regional and international experience in Project and Facilities Management & Maintenance research, advice and academia.

Dr Quah led the EU funded project BE4213 Condition Assessment and Maintenance Strategies for Buildings and Building Components, which among other things, sought to develop an objective building condition assessment system. This project formed part of ongoing research over the last 20 years which culminated in Dutch Standard NEN 2767 on Condition Assessment of Buildings, believed to be a ‘world first’.

Dr Quah’s professional and research affiliations include being Coordinator of the International Council for Research and Innovation in Building and Construction (CIB) Working Commission 70 on Facilities Management and Maintenance for a decade and past President of the Chartered Institute of Building Singapore Centre.  She was also a member of the Royal Institution of Chartered Surveyors (RICS) Asia Board, Singapore Board and Asia Pacific Sustainability Board.

Dr Quah was conferred an Honorary Fellow by Oxford Brookes University for her work in real estate and construction education and the unusual impact her career has had on this particular academic field in Asia.

Er Yong Shan Chi

Mr Yong, a Professional Engineer (Civil) has extensive design and construction management experience. He started in design work with the HDB, moving on to the private sector where he was involved in foundation engineering and precast concrete work. He was instrumental in introducing the Autoclaved Lightweight Masonry Wall system and was in the forefront of the UOB Tower project, the first building with unitised Curtain Walls. He has been involved in D&B projects in Singapore and China providing project management and engineering design support. Mr Yong has developed learning material for CITI and lectures in modules such as Building Envelope and Precast Concrete water-tightness for them.
