Mound Clay

Mound Clay is a finely screened material that comes from our A-1 Red Infield Soil.  Our Mound Clay is screened over a finer screen leaving a higher clay content. With optimum moisture and proper grooming, Mound Clay provides a consistent playing surface for baseball and softball infields.   Ideal surfaces for applying Mound Clay on a baseball/softball diamond would be where the batter plants his/her feet or where a pitcher plants his/her feet.

Mound Clay should be installed and compacted in lifts at a uniform depth of 4” - 6”. It is recommended that a professional laser grader used to slope the infield for proper drainage. When repairing infields by adding additional infield soil, the existing infield should be before incorporating the new soil. This provides a homogenous transition layer and prevents “sheeting.” After installation, properly water the infield until there is a light sheen of water on the surface to allow the soil to settle. *The proper amount of water ensures the best possible playing surface.* The infield soil is designed to compact. If the soil is allowed to dry out, it will harden. If too much water is applied it will become slick. The proper amount of water provides a firm, consistent, playable surface.
