EG CORE is a premier provider of microtunneling and pipe jacking services across Egypt. Our technical expertise allows us to install critical infrastructure beneath highways, railways, and existing buildings without surface disruption. By utilizing high-capacity hydraulic jacking systems and remote-controlled guidance, we achieve sub-millimeter precision for gravity sewers, water mains, and telecommunication conduits.
Our primary strength lies in our adaptable methodology. Whether a project requires a Closed Face Slurry TBM for water-logged sands or an Open Face setup for stable, dry geologies, our forensic engineering approach ensures that we mitigate risk before the first segment is jacked. We handle everything from shaft construction to the final lubrication management of the pipeline string.

The Hasaballah Al-Kafrawi Axis project serves as a definitive example of EG CORE's ability to overcome unforeseen geological resistance. This project required the installation of a 1.2-meter diameter pipeline over a massive 800-meter total drive length.
The Geological Crisis: During the drive, our team encountered a significant stretch of high-density rock strata that was not fully documented in the preliminary soil report. Standard mechanical excavation stalled as the rock hardness increased.
The Manual Breakthrough: Utilizing our Open Face methodology, we deployed specialized crews inside the shield to perform manual excavation using jackhammers (pneumatic hammers). This "hand-mining" precision within the safety of the shield allowed us to fracture and remove the rock obstacles that would have broken a standard slurry machine. Combined with advanced lubrication to manage the friction of the 800m string, we successfully completed the drive with 100% alignment accuracy. This case study highlights our readiness to use manual intervention techniques to solve the most difficult rock challenges in the Egyptian landscape.
EG CORE maintains a diverse fleet of equipment capable of tackling the varied soil profiles found throughout Egypt. From the soft Nile silts to the compacted limestone of the desert plateaus, we select the machine that balances speed with safety.
Our Open Face Microtunneling is particularly effective in urban Egypt where undocumented obstructions—such as concrete foundations or large boulders—can halt a project. Because the face is accessible, our engineers can use manual tools like jackhammers to clear the path, as demonstrated at the Hasaballah Al-Kafrawi site. This flexibility reduces the risk of "stuck" machines and keeps mega-projects on schedule.

Underground work in Cairo and Giza is a forensic science. With decades of local geological experience, we understand the specific friction coefficients of the region. By combining manual expertise (jackhammering) with modern hydraulic jacking, we ensure that your utility infrastructure is installed safely, accurately, and without damaging the vibrant city above.
