Soil Tests (site classification) for residential dwellings, industrial, commercial and institutional buildings, be they part of a subdivision or an individual allotment or building extension are required to assess the subsurface conditions and therefore enable design of appropriate foundations.
SITE Geotechnical regularly undertake these types of investigations in accordance with the Australian Standards:
- AS2870-1996: "Residential Slabs and Footings - Construction"
- AS1726-1993: “Geotechnical site investigations”
Your site is namely classified based upon the expected movement of the foundation soils - generally related to the capacity of the soil to shrink and swell.
The following classifications may be typically given:
- Class A: Little or no ground movement
- Class S: Slightly reactive sites
- Class M: Moderately reactive sites
- Class H: Highly reactive sites
- Class E: Extremely reactive sites
- Class P: Problem site
