Depending on the water content of a soil, it may appear in four physical states: solid, semi-solid, plastic and liquid. In each state the consistency and behaviour of a soil is different and thus its engineering properties differ. The Atterberg limits tests provide a useful measure of soil reactivity and thus potential ground movements, which are fundamental in foundation design, road construction and urban developments.
In our Piara Waters laboratory, we can conduct all Atterberg limits investigations, including Liquid Limits, Plastic Limit, Plasticity Index and Linear Shrinkage testing in accordance with Australian Standards 1289.3. Atterberg limits are generally conducted as part of a Geotechnical Investigation to provide information to soil reactivity that might impede development.
