A lot classification is a series of tests conducted on a site to classify the soil conditions, enabling the engineer to design the building foundations.

A geotechnical investigation is undertaken and the soil is identified, described and classified [eg (CL) silty clay, low plasticity] in accordance with Australian Standards AS 1726.

The investigation report is very important prior to building your home, it allows you to fully understand the soil you are building on.

Understanding the type of soil you are building on is very important prior to commencing construction of your home.

Our lot classification will assist in determining the required depth of your foundations, so you better gauge the foundation costs up front before you commence your project. Normally foundation costs include variations which are not finalised until inspected by an engineer at the time of the concrete pour.

We do this by having a more thorough Site Investigation which includes drilling two bore holes and taking three DCP/PP measurements to the depth required. This inexpensive investigation will give you piece of mind and will enable builders to more accuratley determine the foundation costs without taking risks.

Our report includes:

  • Field tests (where required)
  • DCPs (Dynamic Cone Penetrometer)
  • PP's (Pocket Penetrometer)
  • Fall of site
  • Wind classification
  • Soil classification
  • Bore hole drilling
