Installation from excavation through restoration

Underground construction depends on route planning, existing utility information, access, depth, materials, crossings, and restoration requirements. J-Mar coordinates these conditions with the project team before and during field installation.

Depending on the route and project requirements, work may include conventional trenching, conduit plowing, directional boring, excavation, conduit placement, backfill, compaction, and surface restoration. This allows the installation method to match the actual field conditions.

Send the plans, location, and schedule.

Send the route, utility or conduit details, required depth, plans, known crossings, project location, and schedule. J-Mar will review the installation requirements and field conditions.
