Intra J is the first one of the group of companies incorporated under the name Intra. Once founded as a universal construction organization for the gas objects, it became an original incubator for the new directions and divisions.

Intra J originally specialized in the installation of the gas networks, then mastered heat engineering works, and now these two directions are approximately equal in volume. The development line is based on the complication of tasks, introduction of novelties, which were first mastered by the company experts in Latvia. Therefore many objects of Intra J created precedents for the colleagues, who later adopted its experience.

Since 2006 the company Intra performs works on the Latvijas Gāze high pressure highways and Inchukalns underground gas storehouse. Virtually it means the ability of the experts and workers to provide the highest level of safety and reliability of the objects, among which there are both pipelines and gas-distributing stations (GDS).

In what concerns the turnover, Intra J was and remains the leader in the Intra group.
