• The breaking out and removal of approximately 50,000m³ of reinforced concrete slabs and foundations.
• Improvement of the bearing and settlement characteristics of the soils.
• Improvement of the landscape form.
• The stabilisation and capping of all recorded mine entries and the backfilling of existing basements and other voids.
• The bioremediation of 12,500m³ of hydrocarbon contamination
• Drilling and grouting to stabilise buried coal combustion
• Extensive chemical testing and analysis.
• The diversion and raising of a number of lengths of existing deep surface water culverts and foul sewers.
