Damage to concrete from seepage.

Damage to concrete from seepage, identified by Peter Weddell, owner/operator of Qld Home Buyers Inspection Service and Queensland Building Inspection Service, QBIS

Seepage through paving is causing deterioration of concrete of the sub-floor area below.

Although not significant at this stage it will continue and can become costly to rectify the longer it is left without repair.

It is much better to address this type of problem, sooner than later!

Seepage causing damage to concrete

More evidence of seepage and deterioration to concrete, starting to occur.

Patch job. This has not fixed the problem at its source: 

This photo shows unprofessional patching around the affected surface of the concrete slab below the paving. Further patching below without fixing the source of the problem would a waste of money.

Poor repair:

More seepage to another section of the concrete after being patched. This indicates that the problem has not been rectified and is continuing to cause problems.

Seepage was also evident to garage of the sub-floor below which will also damage stored items.

This problem may seem minor, but in my experience, seeing damage to other similar buildings, in no way should it be underestimated as further seepage may result in spalling (concrete cancer) over a period of time. At the least it must be closely monitored for further signs of deterioration with time frames documented and photos for reference.

Rectification required:

The only effective way to rectify this ongoing problem (for the long term).

  • Remove the tiles covering the paving.
  • Apply a water-proof coating then re-tile the paving.

This should have been carried out during construction of the building, but for cost saving, it was not.
