The new Capillary Edgevantage is a revolutionising Innovation in bunker edge construction and finally allows for edges with natural or artificial edge, and endless design options.
Capillary Edgevantage is mounted vertically and locked into a stable foundation at the bunker shelf, in the liner.
This construction supports turf, sod, or soil from behind — not just at the surface — creating a stronger and more durable bunker edge.


Units can be stacked to build higher edges without loss of stability.
Thicker profile resists collapse without creating a hard rebound surface.
Edge is mounted upright and locked into the Capillary Material via barbed spears.
Integrated cups hold water and keep sod and turf hydrated at the edge.
Spears are cast into the shelf or edge structures below, preventing movement.

We are proud to have constructed some of the world's top 100 golf courses, from Ryder Cup to PGA venues. Here are what some of them say about us and our bunker liner:
All tied together by our proprietary Capillary Material

The Capillary Edge guarantees that the bunker’s shape will remain true to its original design throughout its lifespan. This stability reduces the crew’s need for edge trimming and negates the necessity for remodeling or reshaping bunker edges every decade.
Thanks to its proprietary Capillary Material, the Capillary Bunker Liner excels at swiftly draining excess water while simultaneously retaining the right amount of moisture. This ensures impeccable playing conditions in any weather and across all terrains, while also preventing the washouts and maintenance headaches typically associated with bunker upkeep.
The Capillary Wash Box is an effective solution for washing algae, debris, silt, clay, and organic pollutants from bunker sand. By doing so, it preserves the sand’s percolation rate, color, and desired playing properties, while it is also eliminating the need for frequent sand replacement.
Capillary Edge is the strongest and most efficient method of constructing a durable, single layer bunker edge using artificial grass strips. Here is what sets it apart:

The system is integrated into the bunker construction process and does not require additional specialized steps or equipment, allowing installation to be carried out efficiently as part of standard bunker work.
By relying on structural support rather than repeated reshaping or reinforcement, the edge reduces material use and ongoing maintenance inputs over its lifespan.

The defined edge provides a clear reference for trimming and edging, which, together with structural support from behind, helps the bunker retain its intended form and dimensions over time.
Built using CapillaryFlow’s proven materials and construction principles, the system is designed for long-term performance and backed by established product guarantees.
The structure supports sod and turf from behind, reducing edge collapse and deterioration and allowing natural grass edges to remain stable and intact over time.

High-traffic bunker edge
Are people entering your bunker from the same angle due to steep faces on the other side of the bunker? Capillary Edge lets you protect those edges in a cost-efficient way.
Looking to maintain a neat looking bunker without stacked edges? Capillary Edge is the most affordable option for having multiple bunkers on your course with a single layered edge.

Tree roots won't compromise the bunkers
Capillary Edge protects the outer edge from surface level tree roots or grass growing into the bunker, or animals digging their way through your bunkers.
Yes. Capillary Edgevantage is designed to be integrated with the Capillary Bunker system and relies on Capillary Material or associated edge structures for proper anchoring and long-term stability.
Capillary Edge helps create a fully sealed bunker. It prevents debris from the soil or grass edge from entering the bunker. It ensures the bunker’s design integrity with regard to the shape and perimeter is not compromised and that it remains consistent.
Capillary Edgevantage is designed with a soft but stable face. While balls may bounce, the surface is dampening and forgiving, minimizing hard rebound while maintaining edge stability and safety for players. The thicker profile simply resists collapse without creating a hard rebound surface.
Yes. The system supports both single-layer and stacked edge constructions. Units can be stacked to achieve greater height or steeper profiles while maintaining stability and design integrity.
Capillary Edgevantage helps preserve bunker design integrity by providing a clearly defined and structurally supported edge. By supporting turf and edge materials from behind, it reduces edge collapse, contamination, and gradual deformation, helping the bunker retain its intended shape over time and protecting the performance of the bunker liner.
Yes. The defined edge creates a controlled transition between the bunker and surrounding ground, reducing the risk of soil, organic material, or debris migrating into the bunker during play, weather events, or routine maintenance.
Capillary Edgevantage works with natural sod, artificial turf, and other plant-based edge materials. This allows for a wide range of aesthetic expressions, from traditional sod-faced edges to more natural or contemporary designs.
Yes. The system can be adapted to various bunker geometries, including curved, irregular, and traditional forms, allowing architects to match the edge design to the overall course character.
Yes. CapillaryFlow provides guidance on design intent, material selection, and installation as part of the overall bunker system, ensuring the edge performs as intended over time.
