Sasol LCCP


Cajun was awarded civil, concrete foundation, underground pipe and deep foundation work for the first of two new facilities. The overall program involves construction of a $12 billion ethane cracker, which will convert natural gas to ethylene.

Cajun’s site work scope includes preparation of a 1,150-acre site, establishment of two retention ponds and installation of all underground piping. Other work includes major foundation, underground piping and deep foundation (piling) work for the ethane cracker and a linear low-density polyethylene process unit. Foundation and underground work for offsite utility and infrastructure support systems/facilities for the six process units already planned for the expansion is also part of the scope of work.

Additionally, the offsite utility and infrastructure support systems/ facilities work includes interconnecting pipe racks; a large capacity cooling tower and associated foundations; site preparation, drainage and foundations for rail-loading spurs; site substation foundations; storage tank and boiler foundations; raw water treatment clarifier unit foundations; alcohol unit foundations; electrical duct bank and control room data conduit underground utility; and permanent plant asphalt roads.


  • Both Cajun and its client are committed to sustainable operations. This focus includes the beneficial use of trees that have been harvested as part of the site preparation. Accordingly, Sasol recently donated a portion of the felled trees to the Calcasieu Parish Sheriff’s Office Farm Firewood Program. Cajun assisted with the loading and transport of the trees to the office’s facility.
