I am a high school sb coach at a small school, we had the sb field reconstructed because of construction at the school, the company did a crappy job on the field and the pitchers mound and the batters box has nothing substantial under the clay kitty litter they called a red clay infield, of course they went belly up and have no one to fix it, any suggestions on what kind of a base I could put in those areas that would hold up and be safe?
