Results
Delivered critical drainage infrastructure supporting the long-term stability and performance of the reservoir embankment.
Maintained safe operations in steep, high-altitude conditions without disruption to adjacent construction activities.
Integrated efficiently into the broader dam construction programme, supporting timely progression of works.
Contributed to improved water management and slope performance across the project footprint.
Project
Solution
Installed sub-horizontal drains across designated embankment sections to relieve pore water pressure and improve long-term slope stability.
Deployed specialist drilling equipment capable of operating safely on steep grades while maintaining accurate drain alignment.
Sequenced works in close coordination with earthworks teams to ensure drainage installation progressed in step with embankment construction.
Implemented strict environmental controls to manage drill cuttings, water discharge, and site runoff in compliance with project requirements.
Project
Challenges
Steep embankments with limited bench widths restricted plant access and required specialist drilling and installation methods.
High-altitude working conditions introduced variable weather patterns, temperature swings, and reduced working windows.
Drainage installation needed to be sequenced carefully to integrate with earthworks and embankment construction activities.

Project
Overview
Geovert was engaged to deliver surface and subsurface drainage works at the Chimney Hollow Reservoir project in Colorado. The works formed part of the broader dam and reservoir construction program, requiring installation of drainage systems across steep embankments to manage surface water and protect long-term slope performance. Operating in a high-altitude environment with restricted access and variable weather conditions, the project required careful coordination with ongoing civil construction activities while maintaining strict safety and environmental standards.
