SINCE 1975

Since 1975, Loiseau Construction has been moving dirt and aggregate in the Flandreau, SD area. Jim Loiseau started the family business when he began maintaining township roads and building terraces for the townships in the area. As the employee and equipment list grew, Jim started to have more interest completing work for the South Dakota Department of Transportation. Now Loiseau Construction mainly performs work for the state of South Dakota on larger grading projects and hauling aggregate, with the occasional work with private contractors and in local townships. Loiseau Construction is now run by Shaw Loiseau and Jennifer Latham. Loiseau Construction is continuing to grow while building strong relationships with other contractors and departments.
