For MRT, a sale is only the beginning of our relationship with our construction clients. Through the MRT Technology Center, we provide continuous "best practices" guidance to our customers allowing them to maximize the use and efficiencies of our high-quality, low-cost, coal combustion products. MRT's logistics staff works with the customer in determining whether product delivery should be bulk or bagged by truck, barge or by rail. With one of the largest fleets of rail cars in our industry and backed by the buying power of our parent company CEMEX, MRT logistics allow MRT to successfully compete in most markets. Finally, MRT's Technical Service Representatives work with our clients every step of the way to ensure they are receiving the support they deserve.
