Every superintendent knows that bunker washouts are one of the most frustrating maintenance challenges on a golf course. After heavy rain, you’re often left with sand that’s washed down the faces, contaminated material at the base, and hours – sometimes days – of labor to get bunkers back to playable condition. 

But why does this happen? 

If the bunker construction system underneath the sand isn’t designed for optimal drainage and moisture control, rainwater quickly erodes sand from faces, pools at the bottom, and contaminates clean sand with surrounding soil and silt. This not only impacts playability but also leads to ongoing maintenance costs and sand replacement. 

A Proven Solution: Capillary Bunkers 

. 

Capillary Bunkers is a bunker liner and drainage system engineered to eliminate washouts, maintain sand placement on faces, and reduce sand contamination.  The system combines a strong, durable liner with capillary action technology to ensure: 

• Rapid drainage after rainfall 

• Consistent moisture levels in the sand, improving playability 

• Significant reduction in maintenance hours post-storm 

• Less frequent sand replacement due to reduced contamination 
  

Capillary Bunkers is trusted at some of the world’s top courses, from Ryder Cup venues to PGA Tour stops, where performance, durability, and playability are non-negotiable. 

Cleaning Your Sand with the Capillary Wash Box 

 
 
Over time, even well-protected bunkers accumulate silt and organic debris. The Capillary Wash Box allows you to clean bunker sand efficiently, removing contaminants while keeping your sand in place.
