We have considerable experience with the management of work in areas that contain potential acid sulfate soils (PASS) and/or actual acid sulfate soils (AASS).
Our engineers and scientists are experienced in the identification of ASS and will undertake field screening tests to separate ASS from other inert soils which may be encountered during excavation. We have in-depth knowledge of ASS classification and tracking requirements. By using our Hitachi Soil Recycler, we can accurately treat the ASS with the necessary amount of chemical reagent. We have undertaken many projects requiring ASS treatment and some of these have also included treatment of water associated with the soil management.
