Soil Testing Geelong

Soil testing is vital for any private, commercial or industrial building site. At Ausfield Site Assessments we provide accurate and prompt service to home owners, builders, contractors, architects, councils and developers.

Our site assessment services include drilling, bore logging, field sampling and testing. Upon request or recommendation we collect soil and/or rock samples from your site for various laboratory tests to determine the soil type and predict how soils will behave. Soil samples can be collected in a variety of methods, such as by hand auger, drill rig or backhoe.

Soil Types

There are three main soil types:

Clays - these absorb a huge amount of water because of their small particle size. This results in swelling and shrinking, called reactivitiy. Clay particles sticking together is called cohesion which gives clay its strength.

Sands - They don't absorbe much water and do not shrink or swell. Sand's strength comes from friction between particles.

Silts - These have clay properties and some sand properties. Silt in soil changes the behaviour of sands and clays.

The design of the building's footings, and some aspects of the building itself, depend on the soil type so it is important to correctly identify what type of soil exists on a site where a building is proposed.

Geotechnical Soil Testing Classification

Soils are classified according to the Australian Standard (AS 2870). These standards have been established so that soil types can be measured and identified within the standard. After the soil type has been identified and given its class, a report will be generated from those findings which will recommend a footing depth to suitably match the soil reactivity. 

Clay soil classification is:

Slightly Reactive:     Class S
Moderatly Reactive: Class M
Highly Reactive:      Class H
Extremely Reactive: Class E

At Ausfield Site Assessments we have a range of site assessment services that ensure your building site is properly assessed before construction.
