The shrink swell test, which combines both the shrink strain and the swell strain, was developed in Australia in the 1980s. This test now underpins a codified approach to the foundation design of lightweight buildings on expansive (reactive) soils in Australia and New Zealand.
This presentation sets out the results of a critical examination of datasets of shrink swell tests undertaken in Auckland, New Zealand and Victoria, Australia and concludes that in these datasets the shrink swell test has a significant shrink strain bias which makes it unreliable as the sole basis for foundation design guidance on expansive soils
One thought on “The shrink swell test of determining Expansive Site Soil Classes is Fatally Flawed”
