Converted garages-seepage and rising damp, identified by Peter Weddell, owner/operator of Qld Home Buyers Inspection Service and Queensland Building Inspection Service, QBIS.

Seepage and rising damp to converted garages

Evidence of rising damp causing the carpet to rot:

  • Rising damp can also cause deterioration to timber
  • Attract termites
  • Cause health problems with inhabitants.

Mould to surface of the concrete also back of the carpet.

  • The concrete slab is not likely to have a moisture barrier fitted below it.
  • This would not have been a requirement for a non-living, garage area, when it was originally built.

Moisture meter showing wet reading. The readings were taken after an extended dry period, therefore the readings are very likely to increase (possibly considerably) in extended periods of rain. Normal readings should be around 80 also green and dry.


Important notes:

  • Termite activity and damage is usually associated with converted garages, rising damp and seepage.
  • Due to problems with drainage and moisture.
  • Moisture often attracts termites as they need it to build their tracks and nest.
