The Best Work Often Happens Beneath the Surface
When people see a mine, a dam, a renewable energy project, or major infrastructure taking shape, they see the finished result. What they often don't see is the groundwork that made it possible. Long before construction begins, critical decisions are guided by the information gathered beneath the surface, helping project teams understand risks, plan effectively, and build with confidence.
For the past 20 years, RDCL has been doing that groundwork, helping clients better understand the land they work on while providing the technical expertise and reliable data needed to support safer and more successful projects. At its core, RDCL's work has always been about more than investigations and drilling. It has been about building trusted partnerships, respecting the communities and environments in which we operate, and helping create positive outcomes for future generations.
Growing with the Philippine Mining Industry
RDCL's journey began through the involvement of Australian and New Zealand specialists supporting the growth of the Philippine mining industry. Through participation in some of the country's early mining developments, the company gained valuable experience and built a reputation for delivering reliable geotechnical solutions in challenging environments. These early projects laid the foundation for RDCL's commitment to quality, innovation, and providing clients with the information needed to make confident decisions.
As the industry evolved, RDCL grew alongside it. Establishing a strong local presence in the Philippines allowed the company to expand its team, strengthen client relationships, and develop capabilities that addressed increasingly complex project requirements. Over the past two decades, RDCL has remained a trusted partner to the mining sector, adapting to changing industry needs while continuing to deliver practical solutions, dependable data, and technical expertise that contribute to safer and more successful projects.
Taking on Bigger Challenges
How RDCL Reduces Tailings Risk - Turning Ground Data into Certainty
Tailings dam failures remain one of the mining industry's most serious risks - engineered structures are exposed to catastrophic failure when subsurface conditions aren't fully understood. In seismically active regions like the Philippines, the stakes are even higher, with dams needing to stay stable for decades after mine closure.
In one project, the client was investigating the residual seismic risk for their tailings structure, to decide whether further lifts were feasible. RDCL undertook deep CPT to 70m to understand the construction history and residual risk of the structure. This baseline data was used in conjunction with pressuremeter and MASW data to allow the client to make and risk informed decision on future expansion.
In a recent project, RDCL supported the Client’s geotechnical investigation of an existing and proposed TSF site. By integrating more than 8 kilometres of surface geophysics (SRT, MASW and ERT) with 20 CPTs, 30 undisturbed samples and 40 field vane tests, RDCL established a comprehensive understanding of subsurface conditions across the site. This integrated approach helped reduce uncertainty in the ground and provided critical evidence to support the Client in evaluating options, and make informed decisions on the best path forward, ultimately minimising project risk.
The overall impact: reducing ground uncertainty, giving the Client greater confidence in managing critical geotechnical risks, and helping protect people, the environment, and operations.
Lessons from 20 Years
Twenty years in the field have taught us that industries never stand still. Expectations around safety, environmental responsibility, and project performance continue to evolve, while projects have become increasingly complex. Through these changes, RDCL has adapted by embracing new technologies, refining investigation methods, and continuously developing the expertise of its people. Perhaps the most important lesson learned is that good decisions begin with good information. Whether supporting mining operations, infrastructure developments, or future renewable energy projects, RDCL remains committed to providing reliable insights that help clients manage risk, make informed decisions, and build with confidence.
RDCL's success has been built on teamwork, strong relationships, and a culture that values safety, accountability, and care for both people and the environment. These principles continue to guide how the company works with clients, partners, suppliers, and communities.
Continuing the Groundwork for Future Generations
As industries continue to evolve, RDCL remains committed to the same purpose that has guided the company for the last twenty years: helping clients understand what lies beneath the surface so they can confidently build what comes next.
We work in partnership with you - identifying risks early, delivering practical geotechnical and geophysical solutions, and providing the reliable subsurface data that supports better-informed decisions at every stage of your project's life cycle.
