Horizontal Depressurisation Drilling

Geovert’s Horizontal Depressurisation Drilling capability reduces pore water pressure within mine walls, improving stability and maintaining safe operating conditions across open pit mining and infrastructure applications. By installing horizontal drain holes into the ground mass, trapped groundwater is allowed to dissipate, reducing hydrostatic pressure that can contribute to instability or failure.

Working in environments where access and safety constraints are common, Geovert deploys purpose-built drilling equipment and techniques to deliver accurate horizontal drain holes across complex conditions. Our approach integrates with broader ground support and slope stabilisation programs, supporting long-term performance while minimising disruption to ongoing operations.

Each project is tailored to site-specific geotechnical conditions, with drilling patterns, hole lengths, and installation methods designed in collaboration with our engineering and client teams. This ensures depressurisation systems deliver measurable improvements in slope performance while maintaining the highest safety standards.
