Abstract
The variable properties of older alluvium under different weather condition led several problems during excavation and piling. Older alluvium is semi cemented sedimentary rock and easily to break during wet season, however harder while dry. Specimen from Desa Tebrau in Johor was tested to obtain it strength. Irregular samples were used due to the difficulties in preparing cylindrical samples at laboratory. Rock index tests such as point load test and Schmidt (rebound) hammer test were tested. However there were zero values during the tests in wet and dry conditions. In addition, the slake durability test was not available due to samples were slake readily in water for less than ten minutes. Therefore, older alluvium deposits required different tests to obtain their strength, such as procedure adopted in soil laboratory test or conducted in situ. Moreover, the sampling and testing of the older alluvium need to carry out at deeper layer which in the confined environment, thus to be actual site condition.
