GeoDuct HDPE Cable Ducting
GeoDuct protects and routes buried power, telecommunications and fibre cables. We supply ducting and fittings and install the duct routes required for utility corridors, road crossings and construction projects.


What is GeoDuct™?
GeoDuct™ is a double-walled HDPE (High-Density Polyethylene) corrugated cable ducting and conduit system engineered for the safe, efficient and long-term protection of underground electrical, telecommunications and fibre-optic cable networks.
Designed specifically for cable management infrastructure, GeoDuct™ provides a robust protective pathway for power, data and control cables, allowing for secure installation, cable hauling, replacement and future network expansion without excavation.
With its corrugated external wall for mechanical strength and smooth internal bore for efficient cable pulling, GeoDuct™ delivers unmatched flexibility, protection and scalability across infrastructure projects throughout South Africa and the African continent.
Manufactured from high-density polyethylene (HDPE), GeoDuct™ combines mechanical protection, installation efficiency and future-proof network design, making it the preferred conduit system for modern African infrastructure.
Designed for African Conditions
GeoDuct™ is engineered to withstand Africa’s demanding environmental conditions, including:
-
Extreme temperature variations
-
High moisture and groundwater exposure
-
Corrosive or aggressive soil conditions
-
Urban and rural installation environments
For high-risk locations, GeoDuct™ can be supplied with rodent-repellent additives, making it suitable for remote installations, mining corridors, rural telecom routes and long-term infrastructure assets.
Future-Proof Cable Management
GeoDuct™ is designed to support future-ready infrastructure. Its smooth internal bore enables easy cable hauling, replacement and network upgrades without the need for trenching or civil rework.
Whether your project is located in Johannesburg, Nairobi, Lusaka or Accra, GeoDuct™ ensures cable networks remain accessible, expandable and protected over the full lifecycle of the asset.
