SummarySite Classification including soil testing and investigation is compulsory across all areas of South East Queensland including Brisbane, the Gold Coast, the Sunshine Coast, Toowoomba and surrounds. What is a Site Classification Report?A site classification report involves soil testing to define the soil reactivity. Where building or extensions are planned a soil test must be conducted to satisfy council requirements and ensure correct design. Water can also cause erosion of some soils which may result in subsidence of foundations and building damage. Where foundation design is not appropriate to compensate for the amount of movement expected, damage to buildings will occur. Reactive soils absorb water and change in volume. Water is commonly the greatest issue when it comes to building damage.

Why Test Soils?Inclusion of these requirements for building of residential homes has resulted in a great reduction in homes with defects such as dropped floors, cracked slabs, cracked brick work and binding doors. Soil testing requirements are outlined in Australian Standards AS1684, AS2870 and AS3798. The properties of the local site soil must be tested and measured. These factors will combine to effect local soils and the building structure above. Changing moisture conditions in the soil cause a change in soil volume. Vegetation, tree roots, slope and local topography may effect on site drainage with roots required to be removed and any drainage issues addressed. Reduced bearing capacity may require specialised foundation design at considerable expense. Potential IssuesThere are a variety of issues to consider when planning to build on a specific site. Usually this service will be offered by a geological consultant, engineering consultant, environmental consultant or drilling contractor with sufficient skills and knowledge. Currently in Queensland a soil testing service may be offered by professionals licensed by the Queensland Building Construction Commission. The classification report is used by builders and engineers to plan building site preparation and provide site specific information to assist in appropriate foundation design.
