Capillary Bunkers is the full-scale bunker system ensuring enduring quality for players and ease of maintenance for the crew by providing optimal drainage and moisture rate in the bunker sand
Don’t settle for just a liner - take advantage of our full-scale Bunker Technology System that’s designed to protect your bunkers, keep just the right moisture level and ensure optimal drainage so you can enjoy pristine bunkers and perfect playability all year round
The system harnesses the proprietary Capillary Material’s exceptional capabilities to maintain optimal moisture levels and provide rapid drainage, all while ensuring unparalleled durability and strength. Here is how it all ties together.
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.
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:
Drains with a rate of 100 inches per hour
Robust and dense liner able to stand +1000 PSI protects the drainage
Rapid drainage of 100 inches per hour and moisturized bunker sand in drier conditions protects the bunker from washouts and plugged ball liesbelow
Patented Capillary Material as a bunker liner moisturize the sand from below and makes it stay on even the most inclined faces
Strong edge, durable bunker liner and good drainage reduces contamination from adjacent soil. If it gets contaminated, you can wash it instead of replacing it
Decrease hours spent in bunkers with ⅔

To install the bunker liner in one bunker generally takes between 1 and 2 hours depending on size. The Wash Box is installed at the same time as the liner and should add no more than 15 minutes to the installation process. The Capillary Edge can be installed either in conjunction with installation of the bunker liner or the day after installation of the bunker liner. Installing the Capillary Edge should take no longer than 60 minutes per bunker.

Regarding temperatures and harsh weather conditions the bunker liner was Engineered in Scandinavia - one of the harshest climates out there. The material has a 23 % void space while water only needs 9 % to expand. This means that it can handle freeze-thaw cycles without problem, isn’t affected by clay-heave expansion and drains precipitation at a high rate.
We have done installations in over 50 countries and are happy to provide you with references in your proximity.
No. The reason for that is simple: No other bunker liner in the market can withstand the high pressure water beam without either displacing too much sand, ripping the bunker liner or damaging it in other ways. The Capillary Material with its superior durability can easily withstand the pressure the water beam creates and wash the sand in its place.
Homogenous mix: No other bunker liner is a homogenous mix with equal strength and durability throughout the whole bunker liner.
No certified installers: We offer you the possibility to work with either your in-house team or a contractor of your choice. The products are easy to install and can be handled by any team.
Longest life span in the market with washable sand: The bunker liner material itself has an expected lifespan of +25 years, while the sand can be washed to its original state and playing characteristics. Together, this will save you large $ in the long run.
Non-decreasing performance guarantee: Compared to other bunker liner options, our performance guarantee covers the full replacement of a failed product over 15 years, with no reduction in reimbursement value. It is not a limited warranty or manufacturer’s warranty - we offer full product replacement no questions asked.

No, you can’t. CapillaryFlow does not support the Hybrid Method and will not provide support or materials if this is adopted. If it has been installed anyway, the performance guarantee is not valid.
The single reason CapillaryFlow does not support the Hybrid Method is because it will cause more washouts. As you break the capillary action the drainage relies on, between the intersection of the Capillary Material and the fabric, more water will back up in the porous space in the Capillary Material as it can’t enter your drain lines fast enough. Putting in more drain lines won’t solve the problem. Ultimately, this will cause many more washouts and in extension wet bunker bases due to the contamination.
