Some typical building defects


Cornerstone Construction Consultants provides services to resolve a wide range of building issues. Some typical issues with which we deal are:
Earthworks, Foundations, Drainage, Pavements and External Works

  • Earthworks – Settlement, Erosion and undermining;
  • Ineffective Surface Drainage – ponding of water, flooding or moisture ingress or absorption; erosion; siltation resulting in a loss of soil permeability; incomplete drainage systems; systems not installed in accordance with manufacturers requirements; systems not installed at the correct grades or falls; systems lacking capacity or compromised by structures ad services;
  • Pavement – exhibiting cracks and settlement; base course and surface failures; ponding water;
  • Foundations – Differential settlement, cracking, rising damp or concrete failure; undermining of foundations;
  • Landscaping – Retaining wall cracking and deflection; failure of paving and paths; corrosion; rising damp; plastering failures; staining; efflorescence; Irrigation system faults; and excess iron or limestone; membrane failure; ponding; drainage;
  • Retaining Walls – instability, deflection, leaking, cracking, expansion, rising damp or surface failure;

  • Hydraulic Services – Leaks, blockages, pipe failures, premature system failure, non-compliant installation, poor or non-compliant operations or lack of maintenance;
  • Electrical – Non compliant services operation; Incorrectly located services; services lacking capacity due to non-compliance original installation; incomplete testing and commissioning and documentation; compromise due to post commissioning works by others; corrosion; termite attack; power surge failure or component failure;
  • Mechanical – Lack of system capacity; variable temperature controls; excess power usage or maintenance costs; corrosion; air pressurisation and ventilation, condensation; mould growth; and defective interface with other services;
  • Fire Services – System failures; control errors; unauthorised modifications; defective or damaged controls; false system alarms;
  • Underground services – incorrectly located, insufficient capacity, leak or lack effective insulation, or other necessary protection.

Operations and Maintenance

  • O & M Manuals, As Built Drawings, manufacturer and contractor warrantees – Lack of documentation at handover or post-handover; erroneous or incomplete documentation resulting in failure to be able to operate and maintain; lack of manufacturers warrantee information resulting in compromise of warranty claims; lack of testing and commissioning records resulting lack of proof of systems compliance ad lack of baseline data;
  • Defect Logging and Reporting and Close Out – lack of effective system and record keeping resulting in failure to manage, assess and comprehensively resolve defects;
  • Building Accessibility – non compliant and unsafe access for operations and maintenance;
  • Landscaping – Retaining wall cracking and deflection; failure of paving and paths; corrosion; rising damp; plastering failures; staining; efflorescence; Irrigation system faults; and excess iron or limestone; membrane failure; ponding; drainage.
  • Lack of or poor Operational and Maintenance Instructions for which the Builder, Specialist Subcontractor or Manufacturer may be responsible. This may result in compromises to safe operation and design life, increased operations and maintenance costs and long term liabilities that are often realised after the expiry of the Builders Liability Period.


  • Waterproofing to Balconies, showers and water features – Poor Surface Preparation; incorrect membrane selection or application; insufficient membrane thickness; failure to install movement joints; insufficient fall; membrane damage by later trades; and design deficiencies including structural movement, lack of fall and overflow provisions;
  • Building Fabric – that is incompatible with building movements including thermal, wind and vibtratory movements;
  • Building fabric and or substructure – that is incompatible with design wind pressures in cyclonic regions or in large complex buildings;
  • Building fabric – construction that is incompatible with the design or manufacturesrs requirements in respect of substructure, strutting, movement limitations, fixing types, metallic properties, coatings and sizes; compromised waterprrofing or sealing details or surface damage resulting in moisture ingress and corrosion and premature failure;
  • Roof Tiles – that leak; are not fixed down or supported; that are incorrectly flashed at services penetrations or at wall abutments, that have incorrectly sized gutters or ineffectively sealed hips or have poor installation tolerances;
  • Metal Roofing that is inadequately flashed; missing fixings or support members; leaks, vibrates in wind; displays surface corrosion; displays poor workmanship, suffers from condensation or is visually inconsistent;
  • Roof Flashings, Cappings and gutters that – are omitted or undersize; lack support or fixing; are poorly installed; lack overflows; pond water, or are corroded;
  • Windows and Doors that leak or vibrate in wind; that don’t operate effectively; that aren’t sealed or lack thermal and acoustic insulation; or are not glazed to Australian Standards;
  • Timber Doors and Windows – Poorly sealed doors and windows that swell and jamb or have paint and surfaces that are prone to premature failure; Unsuitable or defective hardware that is prone to failure or corrosion; Unsuitable weather protection resulting in premature failure and leaking;
  • Insulation – Acoustic, Thermal and Fire Insulation – that may be incorrectly sized, fixed or installed; may be omitted in concealed zones or compromised due to poor installation, damage by later trades;
  • Fire protection Linings that may not be installed to designer or manufacturers’ requirements or may be compromised in concealed zones or damaged by later trades or failure to seal penetrations;
  • Plastering Internal and External – that is drummy, cracked, visually inconsistent, friable and degrading or too soft;
