Magruder Limestone believes that delivering a quality product is an integral part of their success in the mining industry.  Attention to quality is a trait shared by many different employees in the process of turning raw materials into a saleable aggregate.  From the watchful stockpile hauler checking the rock as it is loaded, to the crusher operator's experienced decision-making and watchful eye - the mining personnel play an integral part in the creation of a quality product.

       After the rock products are created they are scrutinized and tested(when applicable) by certified quality control aggregate inspectors.  Magruder Limestone employs two technicians who are responsible for the laboratory testing and stockpile approval of the rock products we sell at all our quarries.  All laboratory testing procedures adhere to AASHTO and MODOT specifications and are performed only by certified quality control personnel.
