From humble beginnings Newcastle Airport has grown vastly and expects 9.4m passengers annually by 2035. Increasing the capacity of the existing storage lagoons is needed to continue meet current and future airport requirements. Due to the high water table there is a risk ground water pressure would cause uplift of pond liners. ABG Pozidrain was recommended to remove any uplift, manage groundwater and allow ground gases to escape. Due to being puncture resistant it also protected the liner. The multiple functions of Pozidrain removed the need for imported stone reducing vehicles to site by 200 and increasing material savings.
