An unmatched performance guarantee

We’d like to take this opportunity to highlight what sets our performance guarantee apart from the competition. While the industry standard is to offer guarantees that diminish over time, we offer a full performance guarantee for the entire 15-year duration. Yes, you read that right – a guarantee that doesn't reduce over time!


All about Capillary Wash Box

The Wash Box is designed to work with all CapillaryFlow solutions, enabling users to easily clean the sand of silts, clays, organic build-up, and other contaminants without the need for removal or replacement. The washing of the sand maintains its percolation rate, keeping it free of debris and excess water. This ensures a consistent playing experience for golfers and provides equestrian arenas with safer and superior footing all year round.

With our Capillary Material and high-performance drainage system already ensuring perfect playing and riding conditions, the addition of the Capillary Wash Box will further enhance the consistency of the user experience.

Here are some benefits of the Capillary Wash Box:

  • Saves time and resources: It allows for easy and efficient cleaning of sand in golf bunkers and equestrian arenas without the need for manual labor or heavy equipment.
  • Enhances playability and rideability: It ensures that sand in golf bunkers and equestrian arenas remains clean and free of debris, providing users with a consistent and enjoyable playing and riding experience.
  • Extends the life of sand: By removing debris and contaminants from sand in bunkers and equestrian arenas, the Wash Box helps to extend its lifespan and reduce the need for costly sand replacements.


We believe that the Capillary Wash Box is an excellent addition to all CapillaryFlow solutions and will provide your customers with the experience they deserve.

Don't settle for anything less than the best. Choose CapillaryFlow – where quality, longevity, and customer satisfaction come first.
