Design World-Class, GISTM Compliant Facilities

Geosyntec is a leading tailings engineering consultancy with a reputation built on understanding and exceeding mining clients’ expectations. We provide tailored solutions and high-level strategic advice across Australia and internationally.

Tailings & Water Dams Management

Using a dynamic design process, Geosyntec creates constructible, fit-for-purpose assets, offering clients cost and schedule benefits along with confidence in their assets’ integrity. To do this, we apply our extensive experience in tailing dams management, geotechnical and geosynthetic engineering, water management, water balance, and tailings deposition behaviour. We can also assist with the design of delivery and decant infrastructure.

Core Capabilities

  • Dam design
  • Closure design and planning

  • Risk reviews and dam break analysis
  • Consequence category assessment
  • Tailings characterisation and deposition modelling

  • Operational plans
  • Emergency planning
  • Annual inspections
  • Constructability reviews

Geotechnical Engineering

On behalf of mining clients, we deliver comprehensive geotechnical investigation, data interpretation, and design services tailored to mining civil works and tailings management. Using state-of-the-art analysis software, we engineer foundations, earthworks, retaining structures, and cut-and-fill slopes in urban and remote environments. We focus on soil-structure interaction to integrate site conditions into every design.

Core Capabilities

  • Planning and scoping
  • Fieldwork supervision
  • Parameter verification
  • Design and analysis
  • Risk and optimisation studies

Civil Engineering

Our civil engineers combine geotechnical expertise with water engineering to deliver robust infrastructure designs for each site. Our structural, pavement, and hydrological specialists use advanced modelling software to make risk-aware decisions that go beyond basic regulatory compliance.

Core Capabilities

  • Earthworks
  • Flood and stormwater management
  • GoldSim water balance modelling
  • Hydraulic structures (spillways, levees, basins)
  • Roadway design
  • Erosion control planning

Geosynthetic Engineering

We are industry leaders in deploying innovative geosynthetic materials for highly challenging mining applications, including the containment of aggressive process fluids and coal seam gas management. Our solutions, including specialised geomembrane liners and bladder tanks, are innovative, cost-effective, and adaptable.

Core Capabilities

  • Liner selection
  • Geocomposite drainage
  • Leak detection and collection
  • Soil improvement using geogrids and geotextiles
  • Independent liner integrity testing (LIT)

Strategic Advisory & Peer Review

Engaging subject matter experts early-on in mining projects significantly enhances outcomes. As trusted consultants, we support the entire project life cycle using a holistic management framework prioritises safety, proactive risk mitigation, and quality assurance to meet our clients’ objectives.

Core Capabilities
