Abstract: A system for and method of remediating existing mud and reducing future mud in an animal stable, pen, paddock, or arena through the use of geocells filled with aggregate matter. A new surface is formed through the placing of a layer of networked geocells filled with compacted aggregate matter on top of the existing stable, pen, paddock or arena ground soil. A geotextile barrier may be placed below the layer of networked geocells. An optional aggregate layer may also be added on top of the aggregate-filled geocells. The geocells distribute loads (weight from the animals) across the soil, preventing soil displacement and mud formation.
