Dual Crossings, One Project
Delivering Gas Infrastructure Beneath a River and a Railway
Two HDD Crossings in Pojuca, Brazil
Prime Horizontal is proud to support critical gas infrastructure with two successful HDD crossings in Pojuca, Bahia, Brazil – executed with precision using ParaTrack2 guidance.
1) Rio Jacuipe River Crossing
• 398 m at 14–15 m depth
• S-type curve (716 m & 743 m radii)
• 16” steel pipe installed via jetting through sandy sediments
• Completed parallel to a main road
2) Ferrovia Railroad Crossing
• 421 m at 16.13 m depth
• Combined radius 621 m (Hz 700 m / Vert 1350 m)
• 16” steel pipe installed using jetting & mud motor, with casing run
• Ground conditions: soft sand, hard clay & rock beneath the railroad
The teams worked through challenging ground conditions to deliver a smooth execution — ensuring safe and efficient gas transport beneath both a river and a railway.
At Prime Horizontal, we combine innovation, accuracy, and trenchless expertise to overcome complexity and keep infrastructure moving forward.
