Raw materials for the Industrial Solutions segment consist primarily of resins, chemicals, and other materials used to manufacture composite mats, as well as materials that are consumed in providing ground protection and other services to our customers. Our blended fluids systems components consist of base fluids systems that have been either mixed internally at our blending facilities or purchased from third-party vendors. These base fluids systems require raw materials to be added, as needed to meet specified customer requirements.
