The process to make quality concrete sand starts with our pit. We start with a quality natural raw material in the ground. Some concrete sand producers have to add a crushed rock bi-product, also referred to as "man sand", to mix with their natural sand because their natural sand is too fine to get the coarseness required in the finished product.

Sand and gravel are formed by the weathering of rocks. Most of the sand in Kansas river systems, such as the Kansas or the Arkansas, comes from rocks that have been washed out of the Rocky Mountains to the west. These rocks are weathered (broken, ground up, and rounded) as they are carried along by the rivers, producing sand and gravel.
