  • "Mar-Co improved drainage to the infield, reduced labour costs for the municipality, and decreased the number of injuries during play with the softer clay. Not only that, but now it looks like the kids are playing on a big-league field, which brings smiles to their faces."

It’s great to see the smiles on the kids’ faces as they walk onto the field. It looks like they’re playing on a big-league field, and maybe they will someday, thanks to Mar-Co Clay."

    "In my 35 years experience in testing and installing baseball and softball field skinned area soil, I recently found the best mixture ever – Mar-Co Clay Ball Diamond Products."

    "In my 35 years experience in testing and installing baseball and softball field skinned area soil, I recently found the best mixture ever – Mar-Co Clay Ball Diamond Products. It’s the best in evaporation rate, playability, ease of maintenance, and stability (resists rutting and moving into the grass edge). And the number overall quality is it doesn’t get muddy when wet. It’s amazing. All my customers love it."

  • "Adding Mar-Co’s #15 Standard mix to our infield and the Clay Track Surfacer to our warning track has greatly enhanced the appearance of our ballpark and made prep time easier. In the spring, we’re playing when most other games are rained out."

  • "The return on investment has been significant. The Mar-Co mix may have seemed expensive up front, but I’ve had more teams asking to rent the diamonds than ever before, and we’re hosting a lot more tournaments now."

  • "We’re very happy with the results on our baseball field since switching to Mar-Co warning track and infield materials. The great drainage of Mar-Co products have allowed us to play when other teams in the county have cancelled due to weather."
