Foundry Sand in Soil Blending Applications What took thousands of years to produce by mother nature is destroyed by bulldozing and stockpiling of natural topsoil. To begin rebuilding that soil structure, amendments must be added to create a sandy loam texture. Recycled Foundry Sand is particularly well-suited as the sand component.
