CapillaryFlow – Shaping the Future of Natural Grass & Sand Surfaces

CapillaryFlow is a greentech company pioneering the construction of next-generation grass and sand surfaces for sports, leisure, and cities worldwide. From football pitches, golf courses, and equestrian arenas to public parks, plazas, and urban meadows, our mission is clear: deliver beautiful, resilient, and sustainable natural surfaces that perform better, last longer, and consume dramatically fewer resources.

CapillaryFlow’s systems are trusted across many verticals and geographies:

• Golf – World-renowned for our Capillary Bunkers, installed at Ryder Cup, PGA, and Olympic venues. Our patented liners, wash boxes, and edge solutions deliver bunkers with perfect playability and drastically reduced maintenance.

• Football, Baseball & Tennis – Our Capillary Hydroponics® system grows premium natural grass for stadiums and training grounds that meet the highest standards of durability, safety, and player performance, while reducing water use by up to 85%.

• Equestrian – Competition-grade grass and sand arenas built with CapillaryFlow ensure consistent footing, rider safety, and year-round usability in all climates.

• Urban Green Cities – Parks, plazas, and urban landscapes are revitalized with durable, low-maintenance grass that cools city environments, reduces CO₂, and manages stormwater more effectively.

Our Technology

At the heart of every CapillaryFlow solution is a trio of innovations:

1. The Capillary Material – A patented, polymer-based engineered medium that is the only building material able to move water both up and down. It delivers unmatched drainage and precise moisture control, ensuring sand and soil profiles always stay at optimal levels.

2. Capillary Hydroponics® – A subsurface irrigation and fertigation system that uses a moving, oxygenated water table to grow stronger grass in sand. This method cuts water use by up to 85%, halves fertilizer needs, and creates deep, resilient root systems.

3. FlowTrack Smart Maintenance – Our AI-powered digital platform that automates irrigation and turf management with real-time data and intelligent recommendations, making every surface more sustainable and predictable.

Together, these systems represent the only fully integrated natural surface technology on the market – combining drainage, irrigation, oxygenation, fertigation, and digital monitoring into one cohesive solution.

What We Have Achieved

Over the past decade, CapillaryFlow has transformed how grass and sand surfaces are built and maintained:

• Redefined Golf Bunkers – With liners that prevent washouts, wash boxes that preserve sand, and edges that maintain design integrity, we’ve become the global standard for premium bunker construction.

• Created the Future of Sports Pitches – Our hydroponic fields are safer, more durable, and more sustainable than soil-grown grass or artificial turf, extending seasons and cutting costs.

• Elevated Equestrian Arenas – Delivered world-class footing and moisture control, outperforming all alternatives in both grass and sand arenas.

• Enabled Greener Cities – Demonstrated how our systems can manage stormwater, reduce flooding, lower urban heat, and sustain natural green spaces with minimal resources.

Our Vision

CapillaryFlow is more than a construction technology – it is a movement towards sustainable, high-performance natural surfaces. By merging proprietary materials, hydroponic science, and digital intelligence, we offer clubs, municipalities, and organizations an alternative to artificial turf and outdated soil-grown methods.

The result: surfaces that protect athletes, horses, and citizens alike, while preserving the planet’s most valuable resource – water.
