During the laying of the pipelines and cables, many obstacles & crosses are faced along the route. Avoiding the open crossing, UNICO Petroleum has been used both methods of Thrust Boring & Horizontal Directional Drilling to pass the pipelines and cables under the highways, rivers, channels, railways and others.

This covers:

• Geotechnical investigation determining proper and safe boring depth based on the nature of the crossed structures, roads, railways or rivers
• In-house capabilities for different boring sizes ranging from 6” for cables up to 48” for pipeline casing
• Pipeline protection inside the casing using special casing insulators and spacers
• Cement injection in the gap between casing and hole wall
