Tailings Dam Capping
Overview
Safe Closure. Long-Term Stability. Proven Capability.
At Oldknow Earthmoving & Haulage, we specialise in the safe and compliant capping of tailings dams across NSW. With decades of experience in mine rehabilitation and heavy earthworks, we understand the complexities of tailings management and the responsibility that comes with closing out a site the right way. Our tailings dam capping services combine practical know-how, geotechnical insight, and reliable machinery to help you meet your environmental obligations and ensure long-term structural stability.
Tailings Dam Capping Services
We offer complete earthmoving support for tailings dam closure projects, including:
- Design implementation and material placement – Following engineer specifications, we shape and compact capping layers to meet geotechnical and drainage requirements.
- Bulk fill placement and compaction – Utilising the right equipment, placing layers at the correct thickness and adhering to set back and segregation requirements is crucial for managing settlement and long-term integrity.
- Stormwater and erosion control measures – Construction of swales, drainage features, and sediment controls to reduce the risk of runoff-related failures.
- Coordination with environmental and compliance teams – Working directly with your consultants, regulators, and onsite personnel to deliver capping works to spec and schedule.
Our Capability
We own and operate a whole fleet of earthmoving plant—including dozers – standard and low ground pressure, from D11 down to D4, excavators, and graders—all operated by experienced personnel familiar with mine site protocols. All equipment is maintained in-house and supported by GPS capability for accurate material placement and grading.
We’ve delivered capping projects across a range of active and legacy sites, adapting to soft tailings, remote locations, and complex geotechnical conditions
Compliance-Focused, Results-Driven
Tailings dam capping isn’t just about meeting closure obligations—it’s about ensuring long-term environmental protection and site stability.
