Many softball fields have a conical grade. A conical grade moves water in all directions for a center point on the infield. Typically the grade is at .3%. With that said, all edges need to be at grade to allow water to exit the playing surface. Any irregularities will “create a dam” on the edge. The following photos were from a recent project on a softball field in Cape Girardeau, MO.
How is this issue repaired? A few simple grade shots, additional material and a 2x4.
First, grade shots were taken to ensure grades were met via a conical laser at the plate and the grass edge. Next a 2x4 was used to bridge the area to determine/verify areas that were below grade.
Conditioner/Pro Slide was pulled away to expose the existing infield mix.
The material was then re-leveled with the board and rolled.
